does it really test how much cold and heat the antifreeze can withstand or does it only measure how much antifreeze you have ??

An engine cooling system consists of cast iron, steel, aluminum, and in some cases, copper. When these metals are submerged in water, electrolysis occurs, basically making a weak battery. The electrolysis is what attacks the metal in the cooling system causing rust and corrosion to occur. The ability to prevent electrolysis and corrosion are some of the first properties lost by the coolant as it ages. Just because the coolant tests well enough to prevent freezing or boiling does not mean that it is still working as a corrosion inhibitor. Different antifreezes have different life spans. Always flush and replace the coolant according to the manufacturer stated coolant life, regardless of how it tests.

This 💯 accurate…. This device claimed my coolant is still perfect… my multi meter test said otherwise.

Just do a drop and refill of antifreeze every 2 years and change water pump, thermostat and hoses every 5 years or 100K is what I have done. And never have had a failed radiator, water pump or heater core in 34 years of driving. About 1.2 million miles during that time. Never an overheat issue. $50 in fluid and 1 hour every 2 years and $200 every 5 years and 3-4 hours labor in my home shop. Good maintenance is the key. Not taking away from your video but I have never bought one of those testers. Spend the money on new antifreeze. When I get a new car to me, I change all fluids...100% all fluids. Even the window fluid. Brakes, diffs, trans, transfer, steering, cooling, oil, A/C refrig and compressor oil. $300 early saves thousands later.

KEEP THE OLD BURBAN VIDEO'S COMING !!!! Love them and I have been fixing my '93 along with you.

Gotta tap it a few time against something. there are bubbles on your arrow. You can see them in the video which makes it way over.

I like to any time I buy a used car to flush the coolant, spill and fill trans fluid, change oil and diff/trans case fluid if they have them. Nothing like a fresh start so you know when it needs done again next.

Heads up people be careful if you're useing the smaller bubble style with the small clear tubeing you may lose that clear tubeing in your radiator/coolant system . Mine fell off and was never able to recover the part. Just thought I'd share my experience. Be safe out there my fellow garage warriors ( SAFTY KEY AND COMMEN SENSE IS KEY )

Major points for showing the water and old coolant!

I’m working on a 2 door 94 Yukon and a 94 2500 suburban your videos are perfect 👌🏾

Freeze/boiling protection isn't the only thing to worry about with old coolant. Part of the additive package is to prevent electrolysis where you can have electricity running through the cooling system and cause corrosion and break down of metal. Especially when you look at all the dissimilar metals the coolant touches, without those additives, you've made a battery. A good way to test it is to take a DVOM, put the pos lead on the pos batt cable, and the neg lead in the coolant. If you register any voltage reading, time to change the coolant out. And this is on top of lubrication properties that dwindle as well.

Thanks, have never checked the Fluids with the tool you are using. Seen it a million time had never used it! With your excellent information sharing, I will get one and start checking my older car/ Suburban. Really enjoy your videos!!

Thanks for posting! A couple observations.....when performing a drain & flush (not a drain and fill), using the concentrate is not only cheaper, but in my eyes a must to acheive a balanced system. The key is knowing the full capacity of your cooling system before adding the new concentrate. So after the system is clear of the old coolant, do a final flush with distilled water (I prefer doing this twice). Then button up the cooling system and add 1/2 of whatever your system holds with the new concentrate. Example, system capacity is 14 qts, add 7 of the concentrate, then top off with distilled water. This gets you very close to the desired 50/50 mix. The other thing about over concentrating your coolant mix, is this can actually hinder the cooling system efficiency and for those of us that live in hotter environments like the southwest desert, that could become a big deal. Coolant is not as efficient at cooling as water. This is less of an issue in the cooler environments.

Hello. in the beginning I did not like your videos but now I like them and watch your videos 👍🏻

Those testers are horendously inaccurate. They usually err on the safe side. To test the coolant accuratly you can purchase a refractory tester from amazon.

Great Job Jimmy We use Calgon Soap with water in the cooling system it's the only home product that we found works in Tractor Trailer And Heavy Duty Diesel engines when OIL is in the coolant we mix 2 cups of soap crystal or more with hot water pour it in the rad and run the equipment with heater on The oil will destoy the hoses and seals if left contaminated in coolant system This flush with Calgon has been used for more then 40 years and taught in the Apprentice programs for mechanics Flush the system with fresh water. Multiple times or open any engine drain cocks if possible We also use a garden hose TEE cut into heater hose top line as it's the highest point in most equipment and run fresh water through the system Then find the manufactors specifications for system fluid amount and add straight coolant first with knowledge some water is trapped in the system and then a simple math calculation tonser at what desired coolant protection you want set Your videos are great

I like to have slightly more water than antifreeze in the system. like 55/45 .. water supposedly transfer heat better than antifreeze does.

very detailed video thanks subscribed

With Dexcool, Flush every two years. Dexcool is great but if air gets in the system, the famous Dexcool sludge will appear. I had to replace the radiator and overflow tank due to the sludge. Clogged up the heater core too but luckily I could salvage it. I still use Dexcool but flush every two years no matter what.Two gallons of Dexcool is WAY cheaper than a radiator and overflow tank.

Sorry to be the barer of bad news Jimmy but you are wrong. It is not good for your coolant to be over concentrated and by you tester yours is way over. Anti-freeze is not as good of a coolant (heat transfer agent) as water and it has a higher viscosity. Anti-freeze is to keep your coolant from freezing and it has anti corrosive additives plus water pump lubricant. Being over concentrated will make your engine run warmer to the point of not being able to run cool enough at all in the summer in a traffic jam. If you live near LA you should be at 50/50 concentration and no more because it doesn't get that cold there. Even in Alaska or Maine you should never be over 70% AF/30% water. You need to drain all your fluid out, get it down to the temp range for 50/50 mix and put it back in. I saw you refill your radiator in a previous video were you poured in pure anti freeze and then water. Big mistake. Always mix anti-freeze and water to the correct ratio before pouring into the radiatoror topping off the overflow tank. You are far from the first person to make this mistake but it IS A MISTAKE. Also, there is another way to check your anti-freeze... by it's electrical resistance. There are KZread's on it. I prefer the little gadget you have, mines about 30 years old and it is my second one.

I remember a long time ago reading that you don't want to over concentrate with antifreeze because at a certain point your engine will start to actually run hotter than using the recommended 50/50 mux.

Refractometer are more accurate tool. So this is not the only measuring method.

NOTE: This hydrometer is only accurate with ethylene glycol coolant. For any newer organic coolant like HOAT you need to use a refractometer.

Saw your video because I need to buy a new tester. Just want to mention that Dex-Cool can be problematic if it's not regularly maintained. I do mine every 2 years. If you leave it in there too long it becomes acidic and starts eating your head gaskets. Also it is not a good idea to mix it at higher concentrations than 50/50 for the same reason. Unless you live in eskimo land and it's really damned cold, 50/50 is good to -34 F So you have a 1995? That's when DexCool started. I have a 2003 and long for the days of the green stuff. Also don't ever mix green & orange, or start using green in a DexCool vehicle. Your cooling system and engine will become something like sludgy brown _ hit.

I haven't used one of those testers for years.

Thank yu in the video aiam from saudia arabia

That engine bay, on a vehicle that old, is so clean it’s giving me anxiety 😥 😂

I could never got my prestone antifreeze tester to work. The tester is sitting somewhere in my tool box. On my Caterpillar they make a product to renew the antifreeze coolant.

do a ph test on coolant

The Jiffy lube I used to work at I did a lot of coolant flushes. The coolant flush machine gets 100% of the old coolant out and adds brand new coolant. The coolant flush machine is connected by disconnecting the upper radiator hose when vehicle is cool enough to not have a stiff hot upper radiator hose. Then connected to the hose with a fitting and the radiator. Then there is small suction hose to suck the old coolant out of the reservoir. Then the machine has the proper anti freeze/coolant and water mix of the correct antifreeze and amount to fill the coolant system of the specific type of vehicle. Then the vehicle is started and allowed to run until the new coolant is pumped in and the old coolant is pumped out, which simultaneously! Then the reservoir and radiator are top off with coolant once machine is disconnected and the upper radiator hose is reconnected. This ensures a 100% antifreeze coolant replacement with new coolant. The starting cost when I worked at Jiffy Lube was $49.99 plus tax. Prices may vary depending on the oil change place and type and amount of coolant also.

Sounds good, but then you have to put the trust in Jiffy Lube employees to actually be competent enough to do their job correctly. And since the 1 time I went there they started my car without any oil I’ll never go back again.

Does it test for acidity? Dexcool as it gets old becomes acidic.

You do not want to be over concentrated. If you have too much coolant to water your coolant will freeze easier and boil easier than if it was properly mixed 50/50. You can also check coolant with VOM. It is not just about color, boiling point and freeze protection! Cheers!

Sorry if this has been asked already, but I doubt it has because I can't find the info anywhere. I'd like to test my coolant, but I'm finding it difficult to understand why everybody is checking the fluid not from the radiator itself, but from the reservoir. From my understanding from what I have read, the expansion reservoir does not actually circulate coolant through the system, it only acts as to 1.) not allow overflow from spilling onto the ground, 2.) does not allow air to enter the system, and 3.) maintains 100% fill in the system if there is a leak, or other issues, such as burn off, or whatever. If what I'm reading is correct, the only time the liquid in the overflow tank could actually be sucked into the system is possible during the expanding / contracting process, or if there is a leak / burn off of the liquid within the circulatory system. So, if people are checking the reservoir for proper concentration of the liquid within the system, isn't that completely incorrect? Please learn me here... I'm dumbfounded and probably wrong.

My truck is about at 146k and it's my second 95 Silverado. I have to agree the glycol cannot transfer as much heat as water will and it's counterintuitive at concentrations over 50%. With a stock tune I switched to a 180° thermostat which is slightly less fuel efficient than the 195° stock. But the engine temperature now stays in a area that I'm now comfortable with some wiggle room for Texas heat. Have you looked into datalogging or using a OBD1 adapter to view engine stats in realtime or get a base profile to compare to for diagnostics? Like 1Road I sometimes get into unexpected expenses trying to "maintain" my truck, but sometimes been surprised like finding my timing was slightly off and adjusting it to 0° and having a better idle.

Yep 96 was the first year for dexcool in these trucks. I have a 99 and only use green all makes all models coolant. Dexcool is too much of a gamble.

antifreeze doesn't cool as effectively as water will....

The antifreeze tester looks really inaccurate. Just testing the density of the liquid doesn't give much information. Heck, even the boiling points given by it are misleading as different impurities change the boiling point by different amounts.

Not the only way. You could always taste it.

Make sure your radiator is grounded. Since the coolant conducts electricity stray voltage will travel through it to find a ground. And because aluminum is the softest metal in the system it is the most vulnerable to damage. To prevent this from happening make sure the engine and frame are properly grounded to the battery. I added a ground from the battery to the radiator. You get electrolysis when you have a potential difference and a bad pathway to ground in your cooling system. The radiator sits on rubber grommets which isolates it from the chassis. If you have current in your coolant then you will be conducting electricity through the radiator. You want the current to go to a ground somewhere else. Some people will disagree but adding a ground to the radiator cannot hurt or cause damage. If anything, it adds another ground to the front of the vehicle.
