the fact that I didn't hear a single curse word throughout this entire series is absolutely commendable

[@FakeLegGreg]

LOL, Thanks for watching.

[@oneyplayes465]

Brother, you are a legend and if no one ever tells you this before, you are legend!!!! We have a 2004 chevy avalanche and a leaking evaporator core; and this process is almost entirely the same except for the airbag sensor location, certain radio wiring and engine bay config. We followed your video second by second. We made it all the way to the actual box removal but then we had to stop for the day. For a break as night had fallen. Just two more screws on the right side, lol.. We will tackle the remainder of the job later on. Thank you so much for being there for the little guys in this world filled of chaos. You are a good man. Love from the caribbean brethren...

[@FakeLegGreg]

Thanks for your kind words. It makes it worth it to know that I have helped you and others with these videos. I hope your repair goes smoothly and everything works as you want it to.

[@autofixer222]

Great job on all aspects including the video. Thanks for putting in the time to pass it on.

[@FakeLegGreg]

Glad it helped. Thanks for watchiing.

[@zackde8795]

Thank you! Saved me much $ and it was cool to do myself. Not perfectly done and few extra screws after. But it worked out. 👌

[@missouritraveler6401]

A tremendous job well done!

[@FakeLegGreg]

Thanks MT. It was a journey. LOL

[@brianwolf1336]

I cut a whole in the firewall from the engine compartment. It exposed the core. I took the hoses off and hooked them up to e new heater core and bi passed the old one. I then put the wall back on using new hardware and sealant. I then put the new core on the firewall, wrapped it in insulation and was done. It took an hour and a half. This is an old ranchvtruck used for feeding and never leaves the property. It would be junked before it's ever sold.

[@tonyflores5882]

Great Job! This looks like a pain! I have to do mine as well. Thanks for the walk through and tips.

[@FakeLegGreg]

I am glad it helps. Thanks for watching. Good luck with your heater.

[@daddyrabbit835]

Man, you deserve a Purple Heart after seeing this nightmare.

[@FakeLegGreg]

LOL. Thanks for watching.

[@eddyalcantar755]

Thanks so much 🙏for your video's..helping me alot

[@FakeLegGreg]

Thanks for watching. I am glad they helped.

[@lifelover2301]

Good Job , but I think I would have changed the evaporator while I had everything out just to be safe !!

[@FakeLegGreg]

Good point and I agree. I had mine replaced the year before by an AC shop. Should have had the heater core done at the same time. Live and learn. Thanks for watching.

[@RaulLopez-qf2zq]

You did amaising job bro thank you I'm also doing mine the only thing I forged to do first was take the ac freon out now I'm thinking how to continue the job dash olmost out but freon still in.

[@FakeLegGreg]

Thanks for watching and the kind words. Yeah the freon thing kinda sucks. Good luck with your project.

[@michaelblew6019]

You sir deserve a metal of honor!

[@FakeLegGreg]

Thanks. I hope it helped you.

[@MrBowNaxe]

Wowza! That was quite the ordeal. Great job...hopin' mine doesn't leak anytime soon! Just curious, did you replace the blower motor while you were in there? Thanks for sharing, that was very detailed and I'm adding to my library for when the day comes for my '99 Suburban.

[@FakeLegGreg]

Thanks for watching. No I decided not to do the blower motor. It will probably bite me later. I hope your heater core lasts forever. Good luck.

[@05molinatsx]

Just a quick tip time saver if you disconnect the harness from the fuse box and wiper motor under the cowl push the harness thru the firewall you can take out the whole dashboard out with almost everything intact just unplugging the doors and body plugs

[@FakeLegGreg]

Thanks for the suggestion. I hope I never have to do this job again. LOL

[@05molinatsx]

@@FakeLegGreg lol I have to do one today for a good buddy if not I wouldn't do it at all lol

[@pinepurvissr.6417]

What else hold the AC box in place?? Texas Fastlife, if I disconnect the harnesses will I be able to get the box back far enough to take the heater core out??

[@05molinatsx]

@@pinepurvissr.6417 yes thats usually what let's it not come out far enough

[@pinepurvissr.6417]

@@05molinatsx I didn't end up takin any harnesses loose under the hood. I just took my air box, battery, ac dryer and the six screws/nuts. That let me get it out far enough to remove and replace the cores.

[@wegottafishdude]

Yep I’m bypassing my heater core

[@9856CB]

Kudos brother, you’d think those fools at GM WOULD HAVE BEEN SMARTER. I have a 2006 2500 GMC if this happens to me and clamp and the hoses and connecting my Honda generator in the bed with wires to a portable heater inside the cab. On your episode six I had a locked and loaded with a double barrel and remove that heater assembly piece by piece🤬. And those engineering knuckleheads created a water pump that you have to remove the harmonic balance to remove one nut that holds water pump it.

[@FakeLegGreg]

Yep, this is one of the worst heater core designs I have ever worked on. Good luck on your project.

[@fishlifeknives7429]

They do it on purpose so you dont work on it yourself. And make the shops money.

[@anthonys1965]

I would like to find the engineer who designed this and take him deep sea fishing and push him overboard 🤦‍♂️

[@FakeLegGreg]

I agree

[@Kotaztrafee]

Ha, good thing they have quick connectors or that job would be a pain in the ass.

[@FakeLegGreg]

Ha ha! Great point. Thanks for watching.

[@tristanthechristian3661]

If you put it in first gear, the dash can come off. Offers much more wiggle room to maneuver.

[@johnsmith6368]

WOW ... I hope I never have to do this to my gmc truck.

[@FakeLegGreg]

Nope, I wouldn't wish this on anyone. Thanks for watching.

[@douglasmueller4684]

I have not done one of these in a new truck before. Only watched 5 seconds of the video. O m g. Easier to put in a coat for the drive.

[@FakeLegGreg]

Yep. Except when windshield freezes. Good luck.

[@douglasmueller4684]

@@FakeLegGreg yes you are correct. A little history. I owned a 73 super Beatle . no heat and drove it all year long. Central ill . lol had a window scraper for the inside too. And yes you are correct , till it freezes on the inside. Thanks for yhe video. Looks like a lot of work. Guess I am most worried about the air bad. Was a fire fighter for years . and they were always a chance for injury or death. 👍

[@douglasmueller4684]

@@FakeLegGreg lol am two days into this and haven't remover the bolts from heater box. Wow could remove engine easier than this.

[@FakeLegGreg]

@@douglasmueller4684 I agree. Bummer.

[@douglasmueller4684]

Ok followed your tutorial and at this time it is going back together. The bolts in the engine bay were a little tricky to find but once I did not to bad. To anyone out there this is a very good description of the work involved. Thanks for the video.

[@Kotaztrafee]

I would have probably had a bunch of busted plastic. I smell antifreeze outside my truck. I sure hope I don't have to do this!

[@FakeLegGreg]

It is definitely a pain. Last I heard it costs about $1700 to have it done.

[@GregoryJohnston77]

Why did you take the whole evap box out? All you had to do was take the top lid off to remove heater core

[@FakeLegGreg]

Did you even look at the beginning of the series of these videos? I am no rookie at this. This heater core is not that easy. You have to remove the dash and the whole box to get the heater core out. Last time I checked it was a $1500+ job and the parts are only about $75. I have done a lot of heater cores in my 45 years of wrenching. This was the worst I have seen so far. Thanks for watching.

[@GregoryJohnston77]

@@FakeLegGreg I wasn't saying anything bad, you did great, but you don't have to remove the box. Just slide it back. I own an automotive shop and I've changed several of these. Granted they're not as easy as a dodge those yoy can change in 45 minutes.

[@FakeLegGreg]

@@GregoryJohnston77 Gotcha. You are probably right about sliding the box back. I wasn't trying to flat rate the job and it is more difficult to get camera angles and lighting inside the truck. Thanks for your input though, there are always more than one way to skin a cat.

[@royquesada5295]

You do not need to remove box. Done it several times.

[@michaelblew6019]

I WANT TO BE A MECHANIC WHEN I GROW UP!😅,,

[@FakeLegGreg]

Thanks for watching.

[@zachosburn2166]

Get a head cam dude

[@FakeLegGreg]

I have one. They don't work as well as my tripod mount because I can't monitor camera angles and lighting with the cam on my head.

[@Chinunit22]

Interesting video, but it looks way too difficult, there's a reason of why auto repair shops going to charge over 1200$ in just labor

[@FakeLegGreg]

It is a difficult job and you are right, $1200 labor.

[@str8goon11]

😅😅 why he took the whole dash off?

[@FakeLegGreg]

That is the only way to get the heater core out unless you cut up the firewall.

[@dickmick5517]

GM designer should be in jail for this design. Kidding for course but at least they could have made the heater core of better, i.e. thicker, material so one wouldn't have to total the truck because of a heater core. Bast***s.

[@FakeLegGreg]

You have a good point. Thanks for watching.
