Thanks for telling people not to get rid of the constant tension clamps. Lots of people think that they are doing an upgrade when converting to screw type clamps which is a big mistake.

@TimmyTheToolman

Yep, I can't remember who first told me about the constant tension clamps but it really does make sense how they are superior because as the rubber ages and shrinks a bit, a constant tension clamp will keep a tight clamp on the hose while the screw type will need to be tightened to achieve tightness again.

Good job Miles. Great to hear our video helped you out. You're very welcome and Happy Wrenching!

Since filming this video, I've learned you only need the heater temperature control knob turned to full hot, BUT you don't need to have the fan on. Turning the temperature control knob to full hot fully opens up the valve and lets the hot coolant flow through the heater core. With the fan on, it draws heat away from the engine and might not allow the thermostat to open fully because the engine isn't reaching full operating temperature. SO, I SUGGEST KEEPING THE FAN OFF FOR THIS PROCEDURE. Update 06/2023 - As part of the cylinder head replacement we did on Sean's 2002 4runner, we did a cooling system flush. When we drained the coolant out of the radiator, we only got out around 5.5 - 6 quarts. The system holds over 8 quarts. So, we did loosen the block drain on the passenger side of the engine block. We accessed the drain through the passenger side wheel well with a long extension and 14mm socket. When we opened it up, a lot of coolant drained out. So, if the same thing happens to you and you don't get close to 8 quarts out from the radiator drain, I suggest opening the block drain to get most of the rest out.

Did you use the block drains to drain the block? If you do, does that get you down to nearly empty on the coolant before a fill?

@TimmyTheToolman

6 жыл бұрын

Winslow273 No, we didn't bother with draining the block. On a T4R.org, a guy showed a picture of how much he got out from draining the block. It looked like at most a half pint to me so I personally don't think it's worth the trouble to drain. Draining the block will still leave residual in the engine, heater core, heater core lines and rear heater lines. So no, draining the block doesn't get you down to empty.

Hey really great video man. Do you think it would be a good idea to remove the thermostat for the flush?

@TimmyTheToolman

6 жыл бұрын

Jason Ramkishun Hey Jason, some people do remove the thermostat to expedite the flush procedure. But, removing the water neck, pulling the thermostat and then putting it back in takes some time as well. So, what you have to figure out is the time you're saving waiting for the engine to reach operating temperature so the thermostat opens on each round of flushing worth the extra labor of pulling the thermostat and replacing it after the flush procedure. I decided I didn't want to pull the thermostat and would just deal with the extra time needed to get the engine to operating temperature each time.

Hi Timmy. Your advice at the end of the video is exactly how I keep the engine cooling system of my 2010 Mazda 5 in great condition. I just drain the used coolant and put new coolant every year. Coolant is cheap. The procedure is very easy. No need to flush with water. It's like having a regular oil change. Preventive maintenance is the key. Also, your video is very clear because you mentioned the right way to calculate the ratio of coolant and water since there are still water left inside the engine block after draining. Other guys here at YT failed to mention it. I am now a subscriber on your channel. Cheers from Japan.

Thanks for the link. The aluminum radiator looks nice. I wonder if there would be less of a chance of a transmission cooler failure with one of these radiators. Do you think the trans cooler is somehow superior to one that would come in a Denso radiator?

Excellent video! Thank you very much for going into detail for us newbies who have never done this. I have a 2001 Toyota Corolla and the coolant I think had 80k miles on it and it was looking black. It took 4 flushes before it came out clear. The cooling system capacity for the 2001 Toyota Corolla is 6 quarts. And exactly 4 quarts came out of the radiator. So 2 quarts left in the engine block and heater core. So I added 2 quarts of the full strength red and then did 50 50 mix with distilled water after. Thanks for explaining the math part of it. Other videos on this subject didn't do that. I didn't have the fancy drain kit which I wish I had looking back. I used a cheap $1 funnel and the issue with that was after adding about 2 quarts to radiator it backed up and then I had to slowly add the final two quarts a little at a time while gently shaking the radiator to get the air bubbles out. The brackets that are holding my radiator are broke and need replacing but it made it easier to shake the air bubbles out. My overflow reservoir is under the battery and I didn't want to take that out, so I got some 3/8 inch tubing from Home Depot and a turkey baster and siphoned the old stuff out and flushed it with distilled water and then siphoned that. The Toyota parts guy said for Toyotas 2004 and older use the red long life, not the pink super long life. But then I have a mechanic neighbor who said that is bs. So I don't know about that. I have a couple of questions. I think I got all the air bubbles out but if I didn't, is it that big a deal? Basically they will work themselves out of the system while driving and then I'll just have to add a little more fluid right? Also you were saying that if you regularly flush just the radiator then you don't have to do the whole system flush. After how many miles do you do a radiator only flush to avoid having to do the whole system? Anyway, thank you very much for this video, made this project totally doable for someone like me who has never worked on anything under the hood. Cheers!

First of all, we're glad you found our video helpful and it enabled you to complete this job on your own. In regards to the compatibility of the pink and red coolants, there is a TSB (Technical Service Bulletin) saying they are completely compatible but the link I provided in the video description isn't working anymore. I think it's next to impossible to get all the air bubbles out of the system on the first try. Every time I have renewed my coolant, the level in my reservoir always drops when I check it a day or two afterward letting me know more air worked it's way out of the system. Just top off your reservoir to the appropriate level based off whether your engine is cold of hot. I usually wait until the engine is hot and then top off the reservoir level to the upper or hot mark. To keep the cooling system in good shape, I like to renew my coolant every 30,000 miles. I know some coolants have higher mileage ratings but I don't feel comfortable waiting 50k or 100k to renew the coolant. Plus, it's super easy to do. Just open up the valve at the bottom of the radiator, preferably drain it into a container with graduated level marks so you know how much came out, and then refill it with a 50/50 mix. If you keep your coolant in good shape, you'll never have to perform a full flush again. Happy Wrenching!

Replaced the radiator on my 1997 Toyota Tacoma yesterday using this process. 2.7 liter. No air. Did 4 flushes with distilled water and the discharge water became clear. Ran the front end up a ramp which raised the front 6 inches higher than the rear. The same type funnel. Drained the system and got 6 quarts of liquid. The total capacity of the system according to the owners manual is 8.8 quarts so added approximately 2.8 quarts of concentrated antifreeze (equal to the 2.8 quarts of liquid remaining in the system after it being drained [ 8.8-6]). And filled the remainder with 50:50 mix. This process worked well but I paid too much for the funnel (from O'Reilly), about $45. Had some trouble finding a decent radiator and had to wait about 5 days for the hoses. About $55 for the hoses. About $165 for the radiator (NAPA). All things included in this replacement cost between $400 and $500. The old hoses appeared to be in excellent condition. The engine nozzles that the hoses slide onto were corrosion free. The truck is not driven in the winter so everything is pretty much pristine in regard to corrosion. Slightly over 300K and going strong. MANY things live in the water. Insects, amphibians, reptiles, mammals, avians, fish, bacteria, and a wide variety of aquatic plants. The "scum" you referred to is probably algae (Perhaps the stuff even in your system. Amphibians live both in the water and on land. Thanks again for the video. It made this an easy process.

@@TimmyTheToolman Thanks. I've been using Prestone for years (close to 60 years actually) and have never hand any issues with it. Of course today's vehicles are in general longer lived than old ones. My manual says, "Your coolant must contain ethylene-glycol antifreeze.", so, by God, who am I to not listen to the manufacturers of the best vehicles on the planet? I think that when I bought my Yota it had green coolant in it and the pink is a relatively new product. A friend told me the pink is organic. I think he meant it's more environmentally friend and less toxic to critters like kids and cats (and groundwater, surface water, etc.) Don't know for sure what the chemical components are and the parts lady didn't know either. Anyway it'll be Prestone green for me for a while. Thanks again for an excellent video. I appreciate someone being able to communicate well. I found the use of distilled water interesting. It makes sense but for years, again about 60, I''ve been using well water to mix with the anti-freeze. And I know most of the water I have used has some calcium in it. I never noticed any issues but today's vehicles last a lot longer than they used to. And Prestone advertises that their coolant "Instantly protects against rust and corrosion" but also states "Water quality matters. Use only distilled water.". So it looks like I'll be using distilled water for at least the last flush.

Hi Timmy, Thank you for the video. A quick point - 50/50 mix will *not* get you to 50/50 final if there is any water in the system. Sienna coolant capacity is 3 gallons. So, let's say for discussion you can drain 2 gallons. 1 gallon of water remains in the system. There is no amount of 50/50 solution you can add to get the final system to 50/50 since it has no extra concentration (beyond 50/50) to treat the 1 gallon of water remaining. You can drain and fil ten times with 50/50 and you still would not get to 50/50 - though you would be close. I suggest you use 50/50 to top off. Use concentrate to drain fill with the use of the hydrometer to get to your final 50/50. Concentrate is typically cheaper per gallon (of actual coolant product). I realize you made your own 50/50 mix out out concentrate. If someone decides the 1 gallon of water is fine not to be dealt that is up to them. However, I politely suggest people need to understand they can not get the system back to 50/50 after adding/flushing distilled water by pouring 50/50 coolant in.

@TimmyTheToolman

3 жыл бұрын

I agree with everything you said. This is why we figured out how much distilled water was left in the system and then added that same amount in concentrate into the radiator first to make the residual left in the system a 50/50 mix. Then we finished by topping if off the rest of the way with a 50/50 mix. The problem for some people is they can't buy an OEM concentrate for their rig. The newer Toyota rigs that call for the pink 50/50 coolant can't buy a 100% pink coolant concentrate. But, what I've told these people is to not worry about it. If they flushed the system, just fill it with a 50/50 mix and call it a day. There's not enough distilled water left in the system to lose sleep over it. Now, for people who live in cold climates, they might want to run an aftermarket concentrate so they can get the ratio to a 50/50 or possibly higher coolant to water ratio in extremely cold climates. But, for most people, a mix close to 50/50 is going to be just fine.

Good to hear. Yeah, this DIY flush would work for any vehicle that uses a radiator and coolant to maintain the proper operating engine temp. Happy Wrenching!

Thank you Timmy, I will follow your advice. One last point please. Should I drain the engine block before the radiator, or will that introduce problematic air into the system ? I know it’s extra cost, but would it be a good idea to flush the old coolant using a 50:50 mixture of red and distilled water instead of flushing with only pure distilled water. If a 50:50 is used to do the flush, then you know that after a few flushes the coolant will be close to 50:50. Also, unsure if distilled water in contact with metals at high temperature can cause corrosion, but if a 50:50 is used to do the flush then we know corrosion inhibitors help to prevent corrosion during the flush procedure.

I doubt it caused much issue using so little of the concentrate, but from what I've learned is that the Long life (concentrate you used) and super long life 50-50 are actually different coolants. The concentrate is Toyota red and the 50-50 is Toyota pink. The chemical makeup is a bit different. For whatever reason Toyota doesn't even sell the pink in a concentrate, but I ended up buying a different brand with the same ingredients/purpose as the pink in a concentrate

excellent vid. just completed a full system flush, thermostat replacement and refill using these steps. the lisle funnel is an excellent product. thanks for recommending it and demonstrating its use. something i noted is how the burps trail off as the engine temp rises, and then start anew once the thermostat opens. this should be obvious with any scrutiny, but the funnel makes this trivially easy to follow if you're in the driver's seat looking at the coolant temp rising via a scangauge. thanks for posting this and all your vids!

You will find prestone cooling system flush kits at almost every car parts store in America. make this the job much easier once installed and completely fully flushes the cooling system. Fittings include a t-shaped tubing insert that gets installed and the pressure hose for the heater core. It has a cap to seal it off when not in use. When flushing the kit includes a anti-siphon fitting that you attach the garden hose to.

I know these kits exist but what I don't like is using municipal tap water to flush it out. The whole reason why you use distilled water is it's void of minerals that can corrode your cooling system. So, I would never recommend people use one of these kits. I know it takes more time the way we do it but our way only uses distilled water and not tap water.

The prestone radiator flush actually worked pretty damn well for me. Mine flushed clear after two rounds of distilled water. I didn't really have to run my system all that long.

Hey Timmy I just completed coolant flush as per your video...your videos are sweet and easy to follow much appreciated...one thing I noticed is that black/grey particles would bubble up into the lisle spill free funnel as the distilled water flowed into the radiator...I would wipe out the funnel with a paper towel each time I ran 2 gallons of distilled water through and it would smear like ash onto the paper towel...I also noticed some of the particles in the reservoir which I rinsed out with some distilled water...hopefully this is nothing to be concerned about...any thoughts or experience as to what the particles might be from? I had a shop do a coolant flush when I purchased the vehicle at 181,000 miles and I did the flush myself today at 239,000 miles...I used Prestone which is what the shop must have used as well because of color...when I drained the coolant it came out the swamp green color, but I didn’t notice any of the particles as the coolant drained out as it would only bubble up into funnel. Overall everything went great!

Hey Joshua, Great to hear you have found our videos helpful. The reason why your coolant looked swamp green is you basically went twice the recommended interval for a coolant renewal. There are now different coolants that supposedly last longer, but in the past, the suggested interval for a coolant renewal was every 30k miles. You pretty much renewed it after 60k. I think that black gunk you're seeing is sludge/sediment that formed in the cooling system from not keeping the coolant in better shape. From here on out, just drain and refill your radiator every 30k and your coolant should stay in really good shape. You could also convert to Toyota coolant which is what I will end up doing with my 2000 4runner. When I purchased it, the cooling system had Prestone Green and I have just kept it that way for the last 6 years and 70k miles. But, I now have a 98 4runner that has the Toyota Red. To simplify things, I'm going to flush the cooling system on my 2000 when I'm next due for an renewal and run Toyota Red in both. There's big debates on the right coolant to run in our 3rd Gen 4runners and people swear that the only coolant to run is Toyota coolant. I don't necessarily buy into this but we obviously can't go wrong with using a coolant from the manufacturer of our rigs.

love you brother, its time consuming so i guess most garages dont bother, they just drain and fill the radiator with new coolant. Which is the better coolant for my toyota corolla d4d 2.0 litre, 131k mile s and 2004 model. Iam in the UK. Much appreciated, especially the non splash funnel idea.

Great video Timmy. Interesting about the heater core valve you mention because on Suburbans for instance coolant flows to the core all the times - at least that's what I believe. There is no valve - for the heater control just modulates the blend door so when you have the control on cold all heater core heat vents to the outside but the coolant flows to it all the time. For my Highlander's I don't know of any valve(s) that are inline to the core and cut off flow. Has anyone validated presence of valves cutting off flow or does the blend door work like described above and coolant flows all the time. Thanks again!

You bring up an interesting point. The method we share in this video is something we borrowed. Take a look at the center of the firewall in your engine compartment near the top. You will see a cable actuated valve that the heater core lines connect to. The way I understood it, the temperature control knob turns this valve adjusting how much of the coolant flows through the valve from the engine to the heater core. So, if your theory is correct, where exactly is the vent that allows the constant stream of hot air to escape outside?

Great videos! Friendly criticism, consider pulling the thermostat if you have to do a flush. You won't have to bring it up to temperature.

Doing the distilled 4-5 times is what I do. But you have to know and understand the amounts so you can figure out how much pure concentrate is needed. In almost all other video I have seen they mistakingly use 50/50 pre-mix not knowing what you point out. In almost all cases you MUST use 100 % concentrate to adjust for the distilled water in the block/core and ultimately achieve ~50/50 mixture for the overall system.. great job!

I've never bothered with draining the engine block on any vehicle I've owned. Some guys like to go the extra mile by doing it and maybe I would too if I had a vehicle with really bad looking coolant. If your coolant is in good shape and you do a drain and refill of the radiator at regular intervals (every 30,000 miles), I don't think the block draining is necessary because you're renewing the bulk of the system capacity by draining and refilling the radiator.

All kinds of chemicals go down the sewer system to a water treatment plant so some water with traces of coolant in it doesn't seem bad to me.

Hey Curtis, I don't think so. The water pump's ability to move coolant through the system is dependent on it receiving water so it can create the pressure necessary to move the coolant throughout the system. If the water pump is sitting there dry, it's not going to be able to "suck" the leftover coolant that's remaining in the engine block, heater core, heater core lines and rear heater lines (if you have a rear heater).

My 1994 3.0 which was SO HORRIBLY neglected and abused had so much rust that the small coolant hose from the block to the back of the throttle body was COMPLETELY PLUGGED for three inches with mud, rust flakes, fibers from the crumbling hose. No wonder the throttle body couldn't keep a good idle. I will close the heaters, drain the anti-freeze, run water thru, etc. Will flush heaters separately to avoid further gunk getting in there.

I didn't know how deionized water compares to distilled water so I looked it up. It seems the deionized process also removes most of the minerals out of the water which is what you want so I'm guessing it's fine to use in coolant. I'm surprised you can't find it in the UK. Almost every grocery store in the the US sells distilled water. Have you tried to find it for sale in the grocery stores? After some further research, deionized water is what some coolant manufacturers suggest using to make the mix. I now remember Toyota recommends using deionized with their Red concentrate to make the coolant mix. But, I have no clue where to find deionized water. What I do know is most people choose to use distilled water because it's readily available and lacks the minerals that tap water has that will corrode your cooling system. So, long story short, the deionized water you used is fine. Screw down clamps do work. What makes a constant tension clamp superior is it's ability to keep the connection tight over time. The rubber either shrinks or loses elasticity over time and the connection can become a little loose with the screw down clamp. The constant tension clamp can self-adjust to the changing hose while the screw down clamp will need to be tightened. With all that said, I think you're fine leaving the screw down clamp in place. Maybe just swap it out the next time you're due for a flush.

If the hoses still look good visibly and are still soft and compliant, they're probably ok at the mileage you're at. When you get over 100k miles, I'd maybe start thinking about it and time the hose replacements with another coolant flush or other big job like a timing belt because you usually remove the radiator out of your way when you're gaining access to the timing belt. Or, if you had the unfortunate situation of springing a leak in your radiator, replacing the upper and lower radiator hoses along with the radiator and radiator cap would be the smart preventative maintenance way to go.

Hey Timmy. Thanks for the great video. I read your description about recommendations for which coolant to use. So how would you recommend going about doing the flush using only pink 50/50 OEM mix? Since after the flush with distilled water there will still be a quart or two remaining water and when you add in the pink coolant the ratio won’t truly be 50/50. I’ve seen one other mechanic girl on KZread named Faye who finishes at the end by doing a flush of only pink 50/50 after a distilled water flush. Then she drains it and pours in pink fluid again. Thoughts? This way just seems so much more expensive

@TimmyTheToolman

Жыл бұрын

Hey Mike, just top off the system with 50/50 when you're done and it will be fine. You will have a slightly less than 50/50 mix but that's OK. Most of the system capacity is held in the radiator. Doing a final flush with actual 50/50 antifreeze to water mix like Faye did is a waste. If you lived in sub-freezing temps for long periods of the year, you might want to run an even heavier ratio of antifreeze to water for the added freeze protection. Water has better cooling properties than antifreeze so your engine will actually run a little cooler with less antifreeze and more water.

A few things I have learned from owning Toyota's; use Toyota Red, do not mix the red with any green coolant as it can cause problems. That is probably why he is replacing his radiator. You can also drain the block on Gen3 4Runners, guessing you can on this one.

Draining out what's in the radiator gets most of the coolant out of the system, so unless I'm doing a flush, I just drain the radiator and overflow container, fill it up with a fresh 50/50 mix, burp the system and make sure the level is good in the overflow and call it a day.

Hi Timmy. Great video. Thank you so much for doing it. Very detailed which I loved. A couple of questions please. I flushed the system a few times. The 3rd time after one gallon came out it seemed to drain very slow even with the cap off. I checked it in the morning, however, and two gallons was the total. Any ideas why? My last flush I drained it (while it was still hot) and by accident left the radiator cap on and it all flushed out nice and quick. After one gallon drained I removed the radiator cap and the rest still came out quick. Must all have something to do with pressure? Lastly, is the overflow bottle included in the total capacity of the system? Have not found that answer anywhere. At this point I have 4.75 quarts of pure red in the system (2002 4runner) so I wasn't sure if this means there was less water left in the system so I should add only distilled water in the overflow or if the bottle is counted separately and I should add 50/50 in the overflow? Thanks again.

@TimmyTheToolman

The reason why the coolant drained out slow is maybe there was an air bubble slowing the draining like it wasn't venting properly for the coolant to drain quickly. I would say you don't factor the reservoir capacity into the equation. Minus the amount you drain out of the radiator from the total system capacity and then add coolant concentrate equal to the amount of distilled water you have left in the engine. When you're all done burping the system and the engine is at operating temperature, top off the reservoir to the full mark with a 50/50 mix. Glad you like the video and you're very welcome.

Fun fact about distilled water is that it's corrosive because of it's high reactivity. You'll never see a metal pipe that runs pure distilled water through it because it will eventually just eat straight through the pipe. It absorbs phenols from plastics, nickel from stainless steel, and aluminum. And it'll absorb carbon dioxide from the air to create carbonic acid which further makes it acidic. Semiconductor manufacturers use DI water in chip manufacturing but they use specially treated and coated pipes all routed through open pipe spaces so they can be routinely inspected. In other words, don't leave straight distilled water in your engine. But it does make a good flush, as you can see in the video, it's binding to all the nasty bits clinging to the inner surfaces of the cooling system and pulling it out of the engine. Once you mix the DI water with the coolant, the coolant stabilizes the mixture, making it inert.

Great video Timmy, it was a huge help! One question, I'm planing on putting a new radiator into my 2006 4Runner with 250K+ miles on it. Should I do the flush before I replace the new radiator, after, or does it matter? Thanks again for the great videos, I'm a novice at all this and you are making my life a lot easier!

I'd do the flush first so you're not potentially getting any crud from the old coolant stuck in the coolant channels of your new radiator. Great to know our videos are helping you out. Good luck with the job.

Hey Timmy,,,is there a benefit/advantage in using Toyota pink/red as opposed to prestone green...if so wht is it...about to do this myself and would like ur input plz, Thank you!

Supposedly the Toyota pink or red has a different chemical make-up than Prestone green and is better for the cooling system for the Toyota vehicles. However, the early year 3rd Gens supposedly came with a Prestone green and then Toyota came out with their proprietary coolant. If Prestone was good back then, why wouldn't it be ok now? My truck came with Prestone green and I just stuck with it. If it had the Toyota red or pink, I probably would have stuck with that. I personally don't think you need to go with the Toyota coolant. My recommendation would be to stick with whatever coolant you currently have. If your coolant isn't looking really bad, just do a drain and refill of the radiator. If your coolant does look really bad, then you probably should do a flush and you can decide at that point which coolant you want to go with. The benefit I see with Prestone green is it's available everywhere. If I have a hose break in the middle of nowhere and I get towed to the nearest small town that has an automotive store, I doubt that small town store is going to carry Toyota red or pink coolant but they most certainly with have Prestone green. So, you'd be forced to just fill it with straight distilled water until you can find a dealership or store that carries it.

Now tht u can look bak on ur work,,,how much time did u let the engine run in between flushes, would help to one, thanks!

Israel Rodriguez I can't exactly remember. It does take a while for the engine coolant to get up to operating temperature to open the thermostat and get the coolant flowing through the whole system. If I had to guess, I'd say we ran the engine around 10 minutes every flushing round.

Tim, called Toyota and they said we should not be mixing the LLC (concentrate) with the SLLC (pre-mixed) because the LLC is for older engines (pre-2004) while the SLLC is for newer engines with aluminum. So if we don't then how do we fix the 1.5 qt of distilled water remaining in the system?

@TimmyTheToolman

If you figured out based off the cooling system capacity of your rig that you have 1.5 quarts of distilled water left in the system, you'd first add 1.5 quarts of pure concentrate if you have an older model and then finish by topping it off with a 50/50 mix. If you have a newer vehicle and all you have at your disposal is a 50/50 concentrate, you're just not going to have a perfect 50/50 mix when you're all done and that's perfectly fine.

Hello, thanks for the informative vid. About to do my first flush on a '06 tacoma. A couple questions: How are you getting the specific temp readings and what is the target temp for getting all areas flushed properly? I have a infrared thermometer if that is helpful. Do you recommend any add in solutions for cleaning/protecting from rust when doing the flush or putting fresh coolant in? Thanks in advance if ya reply!

You can just use your analog needle gauge to figure out if you're at operating temperature to get the thermostat to open. You could use either a scan gauge tool or OBD II Bluetooth reader sending info to a phone app like Torque Pro to get an exact coolant temp. In this video description, I have links to the reader and on/off switch I bought for my rigs. kzread.info/dash/bejne/ZKKKxNmeYteYhJs.html The reader is specific to Android devices. If you have an iPhone, you'll have to choose a different reader. The Torque Pro app is also specific to Android devices but there are apps for iPhones too. You would also need to turn your temperature controls to hot to get the coolant to flow through the heater core and lines. I have never used any other cleaning or protecting products in the cooling system so I can't advise you on that. I would suggest just flushing the system with distilled water and refilling the system with a 50/50 Toyota Coolant/Distilled Water solution.

Timmy The Toolman, This is a great video on how to flush the cooling system when filled with Preston coolant. I have a 2008 4Runner V6 and I the systems is filled with the correct pink Toyota coolant the only problem is that it's old and no longer cooling that well. Do you recommend flushing the system as many times as you did even though I have the correct pink Toyota coolant? I figure you did all those flushes to remove all the green Preston coolant. I would appreciate any recommendations, thank a bunch.

If your engine isn't cooling well, a simple flush might not be enough. You might want to replace your radiator, upper and lower radiator hoses and the thermostat. If you don't want to replace the radiator just yet, I would drain the radiator, fill the system up with distilled water, run it for a while and drain it again to see if you can get more gunk out of the system. The fact that it's not cooling well leads me to believe some of the cooling channels in the radiator are blocked up and a flush might not be enough.

Dude this looks like so much work. Don’t get me wrong, engine maintenance is very important but hoesntly there’s gotta be a faster way. Great video tho, it was very informative. Alright I’ll be waiting for a hater to show up.

It is a laborious process, but the way we do it is the safest bet. Back in the day when I worked at a Chevron gas station, we would cut into one of the heater hoses and install a plastic T that we could hook a garden hose up to. We'd put a directional spout into the radiator to direct the flow away from the engine and turn on the hose. We'd let the coolant/water rain down onto the shop floor and down the sewer drain. When the water looked clean, we'd turn off the hose, drain the radiator and then add a 50/50 mix of tap water and coolant. Knowing what I know now, that method isn't great for the cooling system. Tap water has minerals in it that can corrode the cooling system components. Some people take out the thermostat to expedite the process we do so you don't have to get the engine up to operating temp each flush cycle to get the thermostat to open. If you take out the thermostat, make sure you put it back in with the jiggle valve pointing downward at the 6 o'clock position. Also take a good look at the water neck and water pump housing for a build-up of corrosion where the thermostat seal contacts. You might have to clean it up with some emery cloth or whatever you have, so you don't end up with a leak at the water neck after you're done with the flush procedure.

Do you recommend flushing the heater core with a garden hose by taking the outlet and inlet hose off? And THEN doing this entire process? Or does your process eliminate the need for flushing the core I ask this because I have the wrong color coolant (yellow) in my 01 4runner so I need to flush the entire system.

@TimmyTheToolman

No, I would not suggest using a garden hose. You don't want tap water in your cooling system because the minerals in the water could cause corrosion. Just follow what we show in the video and use several rounds of distilled water. If you turn the heater controls to full hot, that will allow the distilled water to flow through the heater core and heater core hoses.

I ised a green coolant type recently to top off my coolant but after some research, ive found that most people say its not good to mix red & green coolant It was a Prestone Antifreeze concentrate and said it was safe to mix with any other coolant but i dont wanna risk it I was planning on doing a complete coolant flush of ALL the coolant in my system (radiator, engine block, heater core, water pump, Idk if im missing anthing) Im new to working on cars & wanted some advice on what i need to do to get all the old coolant out of my car & replaced with the new 50/50 red Also, how do i know if i have a REAR HEATER or not.

If you watch the video, you'll know how to do a complete flush of your cooling system.

This video was great, thanks! I only had one hiccup though. The job is all done for now but I have a question and maybe someone could explain it. I have a 2004 Toyota Sienna that calls for a coolant capacity of 12.4 quarts. When following these steps as in the video, inbetween flushes… I was able to only drain 4.2 quarts each time (basically 1 gallon) .. not the full 12.4 quart as I had hoped. I ended up having to flush it 8 rounds to get it down to as close as water as possible. It was the longest day ever. Then came down to the final fill.. I had one bottle of full concentrate toyota red and one bottle of 50/50 of the red.. my logic was that if 12.4 quarts (~3gallons) was the total coolant capacity for my vehicle and I was only able to drain 1 gallon.. I had 2 gallons of water in the system after the several flushes. Since there was 2 gallons of pure DI water in the system already.. it would make sense for me to fill up the gallon, in the radiator, with the full concentrate toyota red to make a 2/3 water 1/3 concentrate at best. After the final run through with the car on and removing the bubbles, I noticed the coolant system was still all concentrate. I went ahead, took a half gallon out to replace it with water to make a 50/50 gallon mix of the remaining gallon. My question now is.. why didn’t the full concentrate of 4 quarts mix with the rest of the 8 quarts (total 12 qts) even after starting the car and turning on all the heat on max? Did this mean I only did the radiator and not the whole coolant system? Why wasn’t all in one? or why could I flush all 12 quarts like they we able to in this video? or is this all normal and doing the gallon flush and full just fine ? I appreciate any insight on this ✊🏼✊🏼

I'm not sure what happened with your flush and why so little came out when you drained the radiator. It might be just the way your vehicle is. You did the math and figured out how much water was left in the system so adding an equal amount of concentrate should have made what's in the system a 50/50 mix. On that last round, did you get the vehicle to operating temp with the heater control valve open so the thermostat would open flowing through the engine and through the heater core and heater core lines? This is the only logical reason why I could see that your coolant looked like full concentrate and not a 50/50 mix after you added the concentrate.

1. Do you turn the heater on in order to allow otherwise stagnant coolant to flow? 2. Why is the hose clip so much better than the hose screw down?

@TimmyTheToolman

Жыл бұрын

You open the heater control valve so air bubbles can work their way out from the heater core and heater core hoses. Constant tension clamps can adjust for hose aging and shrinking limiting the chance for a coolant leak at the connection. Screw-down clamps can't do that without manual intervention.

Timmy, I have a 1997 4runner with the 3.4 L V-6. It has approximately 211,000 miles. I bought this vehicle a few months past. The heater wasn't blowing hot air, so I: 1) Flushed the antifreeze, 2) replaced the thermostat. The heat situation did not improve so I 3) replaced the heater core (removing the dash etc). When I removed the heater core I checked the heater water control valve. Looked Ok, opened and closed, no leaks. The heat has improved a bit but not by much. The vehicle will eventually heat-up after its been driven for a while. Could you give me some ideas as to how to improve my heating situation and what may be causing the heater to not work at optimal? The vehicle does not overheat and I don't see and scaling in the radiator, so I'm thinking the radiator is ok. I was thinking maybe there is a flap that isn't opening on the heater box???

Don't know what you would do next. My first thing would suspect a problem with the heater control valve but you said you checked it and it seems like it's operating correctly. When your rig is at operating temp and you have the heat on full blast, is the air coming out of the vents with decent force? Just wondering if it's a blower problem. Does you AC work fine? If the blower is pushing air fine, I'm wondering if there's some type of constriction in the piping that's not allowing a good flow of coolant to the heater core. When we did a recent engine swap, there's a coolant bypass pipe that travels under the intake manifold that the heater hoses attach to on the back of the motor. If there's a blockage in that pipe due to corrosion, I could see how that would cause your situation because not enough coolant is able to flow through the piping to reach your heater core. Check out this video kzread.info/dash/bejne/c6p82M1yfpDOhKQ.html and start watching at play time 26 minutes, 16 seconds. You'll see how the heater hoses attach to the piping I mentioned. If you watch further in the video, you see us lift off the intake manifold and remove the coolant bypass pipe.
