Boy you can say that again. I replaced my heater core in my 93 S-10 blazer 4x4. Even have the factory shop manuals that I bought when I purchased the blazer. Used to be a mechanic back in the 70's. And even though the manual requires the complete removal of the dashboard just like that 😖. I was able to do it without removing the whole dashboard. Six hours later got it in but ended up with at least a dozen fasteners left over 😒. And Luckily no rattles at all still working great to this day. That was about six years ago. Still have her as she was literally a garage queen as I had a company car. Just over 100k on her now and will be the last Brand new car I'll ever buy. And that's exactly why I became a engineering technician. Because they don't engineer cars anymore that people like me that use to love working on their own cars PERIOD. And to think I almost got an avalanche loved the concept of the vehicle Whew.

The Avalanche reminds me of a car I owned in the 90’s called an Eagle Premier. The core went bad and at least three radiator shops refused to even discuss the job. Finally found one who tackled it. It took four days and cost almost $900 after they found a new core. I figured that when they built the car the first item on the assembly line was a heater core hanging on a hook. The car was then built around it.

You can't make every part of every machine easy to get to quickly. Techs complain about engineers because this 1 thing that they're trying to do didn't magically fix itself, while Engineers complain about the constraints and parameters they're having to design to. Specifically on the subject of this HVAC unit; where else would you put it?

I wish I'd had a boss like the Car Wizard when I was in autobody repair. Every place I worked was "rush, rush, rush". That led to dozens of needless comebacks over the years. Man, that made me nuts! Although I've never worked as a mechanic full time I've built a few hot rods over the years. That got my phone ringing as a few auto businesses would call on me to do work the regular mechanics didn't want to do. What do many mechanics not want to do? Heater cores, or any job that requires pulling a dash. So, that's where most of my experience lies - heater cores. They suck to replace but I enjoy the challenge. Never had one as bad as the Avalanche though. I think the worst ones took maybe six hours. Thank God I never had to do one in a Range Rover! The easiest by far was in a 1979 Bronco.

"After the vehicle is out of warranty, it's not their problem anymore" I call this the Airbus attitude. The European plane maker is clear that they do not think that their airplanes should be in the air after about 25 years, despite the number of hours/cycles. Their reasoning is that technology moves forward and older less efficient equipment should simply be replaced. This isn't limited to Airbus; ALL car manufacturers are doing this now. They know that nobody works on their car anymore, and when they get a few years on them, most people simply replace their cars. Or if a major malfunction occurs, they simply trade it in. Thus serviceability takes a backseat to cheaper production costs, and as a result it takes 15 hours of labor to change out a $40 heater core on a modern car, versus 1 hour on "Great Grandma". Great video!

I drive a 2000 Chevy S10 2.2L with 200k on the clock and never, repeat never have I had to replace the heater core. Why? Because I flush the coolant on a regular basis. I also use a quart of lime-away and water every 100k and drive for 100 miles before flushing.

RESPECT to you CarWizard...What a tough job you have sometimes !!!

Great video. I always told my dealer that I am willing to pay even the additional hours, as long as it is done properly. Once they ran in a similar issue and wouldn't charge me the extra costs. I gave it to them via their tip jar. I really appreciate honest work.

I worked on auto assembly line for 19 years for a foreign transplant. Most all vehicles are built this way. Manufacturing expediency. If you saw how the assembly line works, it makes sense, though later service work on a part that goes in first is a nightmare. The body is bare coming out of the factory paint shop. First thing that goes in is the body wire harness. Somewhere early on the line, the heater box goes onto the firewall. The Instrument panel is subbed up somewhere else typically and then goes in all in one piece usually. All the little trim parts then go on. If you are lucky, a few trim covers can be removed and the whole IP can be dropped out intact (after the steering column is out) making it a whole lot easier--less parts to break or have buzz/squeak/rattle problems with later. This truck looks pretty hard. Not seen how this vehicle goes together at the factory to know if it can come out in a less disassembled form. Dealer wanted $1100 to change the heater in my wife's Hyundai Accent. Was more than the car was worth. Stop leak every season when you could smell the coolant for four years kept it at bay until we dumped it. There was a non-authorized work around that meant cutting the tubes that went behind the IP and yanking it out the side of the console where it was mounted, but was too lazy to do it. This is a pretty good example of why it is a good idea to change the coolant frequently--helps prevent the corrosion that kills heater cores and radiators. They got almost 20 years out of theirs--pretty good.

Compare it to on a VW Rabbit, you unsnap two spring steel clips under the dash and voila, the heater core. That’s about the only positive thing about the heater. The fan is very noisy and the heat is lukewarm on a good day.

20 seconds in and I’m anticipating an Avalanche of problems.😳

If it were my car, I would get Bars Leaks Block seal and put it in the cooling system. That has always fixed my internal core leaks. But if that didn't fix it, I would just bypass the core and get a few electric heaters. This is a 2002 vehicle; not worth the cost of repairing it.

I had to replace the Evaporator in my 2000 Silverado. I took my sawzall to the bottom of the dash lol. It worked 🤷‍♂️

I did the heater core in a 98 Ford Expedition. The level of disassembly was pretty much the same as this vehicle, although there wasn't much in the engine compartment. In all, it was about 2 solid days of work to replace it. It's obvious that the heater core was the first thing they installed when they built the truck.

My first real education in car repair was a heater core in an 88 Ford ranger. It taught me the valuable lesson, "some things are worth paying a real mechanic. "

I'm glad you mentioned breaking the plastics because I recently did a similar job on my Avalanche and that plastic is so cheap and brittle. It's nearly impossible to not break anything.

No room under the hood.

You don’t have to completely disassemble every single part in the dash…. It goes in as an assembly, it can be removed as an assembly.

As a shadetree mechanic, *every* job makes me cry 😅

The car companies care about how quickly and cheaply the vehicles can be assembled on the line. As long as it outlasts the warranty, they're good to go.

You are so right about some mechanics doing a rush job and either breaking parts or not tightening screws and bolts or correctly fitting trim back properly. I did just what you said 'NOT' to do. Lol. I purchased all my own parts. My '98 Grand Marquis had a broken flap inside the HVAC box. It had been bad for almost 3 yrs. 2 yrs ago I took it to what I thought to be a reputable garage for repair. At the time the car had just a little under 200,000 miles on it. Since I knew that they would have to remove/loosen dashboard to install the new box that I had provided, I decided to also have the mechanics replace the heater core in my car (the current one was original to vehicle and still working). I also had them replace the HVAC actuator which sits atop the box as well, because it is a pain to replace otherwise. I furnished all the parts and decided since they were going to drain the antifreeze to go ahead and have all new coolant and upper/lower radiator hoses replaced too. I was happy when it was finished because then I could feel heat on my feet through the floor vents for first time in years. But there were numerous clips missing from trim, some trim pieces were not fitted properly, and some parts of dash panels were cracked. I know old plastic can dry out and be brittle. I would not have been too upset about it but I told them there was no rush and that I did not need it back soon. They had it for six days. And when they told me it was ready there was dirt and grease on door padding, carpeting, and on the seats. I would hope more mechanics take pride in their work than these guys did. Overall they fixed the problem and all that I had asked....but I was disappointed with the condition they had left my car in when I picked it up. You NEVER get a second chance to make a good FIRST impression.

My 2001 Tahoe started fogging the windshield, and I smelled that sweet vapor of doom. I looked up what it takes... Snap off some plastic pieces, row of screws for more plastic pieces, row of screws under that for more plastic pieces, more plastic pieces, removing the box, discharging A/C, recharging, reassembling... I remembered how easy my 89 GMC was (10 minutes to remove a row of screws and drop a flexible plastic tray to undo a couple clips and hose clamps). Then I said NOPE, looped the heater hoses and made the Tahoe a summer vehicle 🙃

How in the hell do you guys remember how to put all that stuff back together again.I'm more than happy to pay someone to do that work as long as it's put back together correctly!.

@@KalebKronic yeah. I think in the '95 or when they updated the Ranger the heater core is mounted vertically so the entire dash has to come out 🤣

Just had to do a job just like this. The problem was ignition power, power at firewall and passenger seat, but not in the drivers footwell! After the dash structure was removed (including the aluminum dash plate!) there was a chewed wire. That was on an 05 Monte Carlo, it’s amazing to think that I did all that myself in the second year of Highschool.

But wait there's more. Right on brother. I always enjoy your videos. I like how you are authentically yourself. Hope you and your family have a good Christmas. I just booked a trip to Florida. And I'm going to cycle up the West Coast. After I locate a bicycle, because it's too much of a hassle to ship my own.

That looks like a nightmare! I did my 04 Dodge Ram last summer in our driveway and it was bad enough even with just laying the dash back into the seats. I still can’t believe they build them like this and think it’s acceptable, I guess it’s because most of the cars are out of warranty by the time they fail.

I’d like to see you do a video on catastrophic failures. What leads to failures on major components that makes them practically unrepairable? Are they more common in old or new cars, some brands vs others?

Lack of maintenance is the largest thing that kills cars or reduces the life. Some parts are designed poorly/cheap so it is important to CHANGE THE OIL! Keep things clean. Owners manual service periods should always be considered "severe usage".

Wow!!!! A new respect for what mechanics do-It’s like putting a gigantic model kit back together- extremely detailed- and everything is there but you’ll be there a while

Car wizard that was a really great video. I knew you had to pull the dash but I didn't realize that it was that much work. Really insightful and scary thanks for this video

To be fair there is somewhat of a shortcut for the heater core. If you hook up a hose and flush your heater core out, that can possibly buy you an extra few months or sometimes even a few years before it needs replacing. And you can keep flushing it repeatedly as well. I know this is a trick used by MK4 GTI owners and it can save you a few grand on a cheap car. Definitely a bandaid and it may not work on all cars, but its a hell of a lot better than nothing

To change the blower motor on like a BMW e60 you need to remove the upper part of the dash, but still it's bullshit when Wizard says that 'you have to remove the dash to change the heater core on modern cars'. And fuck that Avalanche is ugly as hell.

Great video! 🙂 Kudos for taking the job on - that's one that I would "nope" out of real quick. Maybe offer to bypass the heater core 😁 I've only done a dash removal once (on an older W126 sedan), but it was my first time and my last time. If you're DIY, you need to have foam, fabric tape, zip ties, and similar interior trim parts ready to go when you reassemble or it'll be jiggling around.

And ya dexcool eats aluminum, plastics, silicone most rubbers so flush that crap out and put green conventional in

You would think because it's a large truck, there would be lots of room and you remove a couple of thing and you got it. Guess not.

The manufacturers also weren't forced to fit in 20 airbags, backup cameras necessitating a screen, be able to roll over 100 times and get smashed by a semi and keep the passengers alive, etc. People like to blame the manufacturers but there are so many mandates on things that vehicles have to have, while achieving better and better fuel economy. That's also why they cost so much more. They have to fit more and more stuff in the same size package. However, I'm not sure why GM specifically made it so hard to get to the heater cores, the F150s of this era and even the newest aren't this bad.

your 1970's car doesn't have nearly this level of content and likely requires significantly more regular upkeep to just keep moving. I took both of my last new cars to 100,000 miles with only oil changes and tire rotations/replacements as the service items. if you told someone in 1970 that you did that they'd think you were lying.

I just replaced the head gaskets and timing set on my v10 Excursion after the thermostat stuck and exploded the radiator. My grandpa came out while i was taking it all apart (engine stayed in and body stayed on) and though it would never run again. 2 weeks later (waiting on parts to come in) fired right up, put a 7500# trailer on it and drove 500 miles problem free. He told me he was extremely impressed because there would have been no way he would have gotten it back together, let alone run lol.

You can thank the misery of this job on the fancy automatic a/c systems and other electronics found on newer cars. One of the things I do when repairing my cars is to make some modifications to make the job easier for the next mechanic (which will likely be me).

As long as the part is at or below the dealer MSRP I see no problem marking up the price I pay as a professional mechanic or shop owner. I am with Car Wizard on this one... if you want to supply the parts then the *only* thing I will warranty is that they are installed correctly. If your part fails then I will charge you the same shop time rate to replace it again. If your part fails, say a timing belt, and it takes out the entire engine... guess who is gonna pay for that engine. Most every shop I ever worked at or ran had this policy. Another thing to keep in mind is most electrical and electronic parts will have a no return policy (depends on local state/consumer protection laws) at all from the dealer. Some discount retail parts suppliers have the same policy. If your mechanic/repair shop supplies the part it will have a warranty. People who insist on shopping around and buying their own parts can be a particular nuisance to a shop. Say you bring your car in for a repair or service but you didn't get all the parts and supplies yet. Do you think that shop is going to wait while you shop around town for the best deal on whatever it is? If your vehicle is taking up a lift or bay most places I know will slap it back together (running or not) and put it in the parking lot. If it sits there more than a coupe of days they will charge you storage.

I'd have to do that job nonstop while it's fresh in my mind.

The easiest one I have ever done was a 1981 Delta 98 that came originally equipped with the 350 Diesel engine. Three screws that hold a cove on under the hood, the two hoses and that was it.

I used to be able to do these and h3's with my eyes closed when I worked at the dealer... I always wished they made the dash come out more like a dodge... not taking every single component out to remove the dash... but after having to lift out a new dodge dash, and how heavy it was(and needing to wait for someone to come help me), I feel like taking out all the individual pieces helped keep me from injuring my back and let me do the job without needing any assistance.

This is stupid because vehicle engines are at best about 40% efficient, most 30ish % efficiency. This means most of the power in the fuel is wasted as heat. You can use some of that heat to heat the cabin, using your alternator to run an electric heater will burn more fuel and burn your alternator up faster than it would have otherwise.

Supply chain issues that you mention are very real for builders of industrial machinery as well. Many custom machine builders currently have their shop floor filled with projects that are 99.9% complete. The problem is that the missing 0.1% is the difference between getting paid for a completed project or warehousing a few of tons of expensive scrap metal.

I'm glad mine was done under warranty! Still had to wait six weeks for the part to arrive, and the mechanic had to put my truck outside with all of the pieces of the dashboard inside the truck. I only saw it because I needed a few things left in the truck and could not wait six weeks. It took one comeback as there was a weird glitch after it was reassembled. The radio speakers would intermittently lose all sound at random times, or whenever I released the foot operated parking brake.

Avalanche's were junk the dealer i was working at replaced a engine or two a week on them first few years. the number of customers screaming in the service lane and at a gm master tech who insisted a quart of oil every 1500 miles was acceptable to chevy guidelines and not a warranty issue. Gm hated to warranty the engines even though they were going through them like crazy. Some just blown up from head gaskets others from the massive sudden oil consumption from first time towing. Sometimes with like 10k miles towed first time bam engine junk.

Designing these modern hvac systems into one module like they do probably saves the manufacturer a few bucks, plus maybe an hour in assembly time. Unfortunately somewhere along the line it is the customer that eventually ends up having to spend 20 times more than what the manufacturer originally saved by designing the units that way. Ease of repair is not even on the list when it comes to modern cars, the engineers that design them don't seem to take that into account. It is all about making it easy, thus quicker and cheaper to manufacture the car. I cannot even imagine just how many modern cars and trucks have ended up down the scrap yard early, simply because a heater core let go. It's simply the modern world we live in. And give it another 20 years it will be so much worse with things like EV's. Battery packs going bad - time for the scrap heap, main control screen and computer go bad - time for the scrap heap. I reckon a EV will only have a life span half of what the older cars had. Does not take a genius to work out that will mean the world will need to produce twice the amount of cars than it used to over say a 10 year period.
