Great video no time wasted right to the point just made my day I was so upset I have to replace my heater core and thought it was going to be a nightmare under the dash and everything thank you so much for sharing this video
Thank you so much! I've been working on my 81' El Camino and somehow managed to break one of the stock brass tubes on the heater core. I bought the part today and I was laying in bed tonight and came across this video; I jumped out of bed, got my shoes on and went and replaced the heater core and just now (12:45am) got back to bed without the dread of having to change it tomorrow. Thanks a million!
Thank you so much I am so glad that you post this stuff. Really helps me fix stuff myself on my 85 El Camino. My heater core (or something) in my AC/Heater unit broke and I have a coolant leak issue. This should help me find the problem, replace the part, and do it right. Thanks a bunch man!
Thanks for this video! I'm in the process of getting my grandad's 86 ElCamino back to glory. Even if I don't do the work myself, it's good to know what needs to be done. Appreciate you.
thank you so much ! I have a 1983 Buick Regal 4 door and my heater core started leaking from the bottom of the car I thought it was going to be a nightmare to change but you made it look so easy!
Thank you for this. I started to experience water on my floors after rains. Friends who own Gbody's told me I need to clean that drain by the blower motor right away because its clogged and letting rain water enter my cab through the floor vents which will eventually rot out my floor. I have been trying to figure out how the hell I have been getting water in my car for months now. This video helped me see exactly where I need to get my hand in to clean that flapper valve. Thank you so much brother.
Excellent job on how to video Brian . I just Took my cover off to change the heater core which has been in there for 37 years in my 84 GP. It was the original factory core! I would like to add an additional step which was left out. You have to remove the brackets for the chrome valance because they are in the way. They are 7/16 nuts 😁
Damn lol I've been working on my dad's 1979 Chevy Malibu wagon and this video is exactly what I was looking for. Thank you so much man. Amazing video and help. You're angel sent from heaven for this lol
This video was very well executed and full of good information. It's always a good thing when you watch a video on how to properly do something without hearing someone say" This thang there sits right next to that thingamajigs!
Excellent video! I have seen many of them and this video is clear, easy to understand, and covered all the information to do the job in a very efficient manner. Keep up the excellent work!
gonna tackle hearter core replacement as mine is leaking.... loved the video however i wish you could have showed the blower motor removal.. just undo some wires and some screws im guessing and squirrel cage comes out? never done one of these change outs but have done lots of my own work on this car,,, thanks for your time,,, df
Excellent explanation. Thanks. I have a 78 El Camino and I want headers. That's a big evaporator box. So close to the exhaust manifold. But the heater core is bad and I have to do this anyway. Thanks again
Creat videos!.. my dad owned a 79 oldsmobile cutlass and I found one similar last fall and im trying to get it working properly to pass her on to my son one day

Very helpful. I actually changed the heater core in my '80 Monte about 4 years ago. Darn thing must've been a cheap make because it just stared leaking again. I'll be going back under the hood soon. Watched your video to refresh my memory. Appreciate the butyl tape suggestion. I like that better than the silicone goop stuff I used the last time. Thanks for posting.
This process is very similar to the C body, and probably B body. It’s actually a little simpler on the C body; no chrome trim plate to remove. Watching this helped me change the heater core on my 83 Coupe deVille.
Man bro I got to say you're videos are really helpful a big thumbs up! love you're videos ben wachn them for a long time now. I love the fact that u make tutorial videos on g bodys that's how I lern how to do things to my 1983 cutlass supreme. keep the good video's goin and keep thos g bodys rolling! like u say! much love and respect from way out here in FRESNO. CA
Well I have a clue. The book attempts to cover too many Models, and addresses only those that are not equipped with A/C. The book directs removal of the "Front Module" then removal of the Heater core. What you worked on is a match for what I'm looking at. Thanks !
Excellent tutorial Brian! It has just helped me get to my heater core and evaporator. Couple of things I would add - on my 1986 Monte Carlo SS, there's two more small screws holding the top half of the airbox lower down in the center of the top half, as well as all those around the circumference. Also, after removing the scuttle trim panel, I also had to remove the two brackets on the passenger side to make enough room for the top half of the airbox to clear when removing it upwards. Lastly, @9.15 when fitting the evaporator, there is this black goop that is being used to seal the inlet. What is this black goop and where can I get it from?
A couple of questions: Is your cover broken and if so, did you reinstall as is? It looks like there are pieces missing. (You can see this at 11:20 in the video.) Second, did you remove all the old butyl sealant before laying down the new? I have a leak into the passenger side footwell of my 1983 Caprice whenever it rains or I wash the car, and I think this seal is where it is coming from.
This was a while ago and do recall the cover being broken as someone was in there prior. I left is as is and added more butyl in those places to seal off any cracks etc. Yes I clean off the old sealant. Many times the actual heater box is leaking where it seals to the firewall but can come from other places. Door hinge bolts, the rubber boot for the power options, windshield. Just need to hunt it down. Its not easy.
Great video. My heater core just started leaking on my 87 cutlass supreme. I noticed my passenger carpet became damp. Would old coolant beneath the carpet causes any long term issues to carpet or surrounding areas? Why would it leak beneath the carpet instead of just leaking beneath engine bay?
i must have blinked and missed you showing how to replace the heater core. And didn't see how you used the black sealant goo for the cover of the box. i wish you would have shown it.
im working on an F body. my a/c is getting to a good temp but it isn't blowing well. I think the evaporator may be dirty. im planning to pull the top cover and clean it. I appreciate the video
Hey my ac evaporator is intact and full of refrigerant but I think the evaporator has a crack because with the ac on u can feel a lot of cool air blowing from the heater box into the engine bay under the hood… my question is do I need to drain the refrigerant before removing the old evaporator or do u think that the evaporator is fine and I need to seal up the heater box better?
Are the small vacuum lines that attach to that ball shaped canister available? I have a small pink one specifically that has crumbled but I might as well replace them all.
I'm just finding your videos and they so far have been a major help in some Areas right now I am actually thinking about removing my AC/heater box in my 78 el Camino the lines (similar to yours) were cut off as we'll I'd like to just put one of those delete panels how much more/ what else would have to be done to completely remove it?
Thanks for watching and glad my channel has helped you. You need to just remove the rest of the bolts that hold the lower portion on. Need to remove the inner well. Remove the glove box so you can access everything behind the dash.
Hello there! I bought an 88 cutlass supreme classic and there's a white mist coming out of the heat vents when the heat is on. I did a little bit of research and from what a gathered, I think it might be the heater core. What do you think?
just found your videos and you know a lot and watching are going to be very helpful. I'm about to buy a 79 Cutlass but no gauges are working on the dash, the aftermarket radio was flickering on the test drive.. any ideas on troubleshooting?
+Matthew Estrada Thanks for watching. I have videos on the gauges on how to swap or fix them. Go here: th-cam.com/play/PL_N4pjeYIeLtMUpNBRhMtKNcRcwYdaDAO.html
I have a coolant leak that's dripping down behind the front passenger tire. This is on my 83 Cutlass. Do you think that's indicative of a bad heater core? Someone mentioned to me, to bypass the heater core. See if the leak stops, and that would tell me it's bad.....
Mr.g.body man . I have a 82 cutlass 4door my heater is busted ,n they did a bypass...im trying to connect my holese back .but i dont have a clue witch holes goes to the left n witch holes go to right. One holes is attach to the waterpump.n another to the intake..i just dont know witch one to connect to the heater core.i dont wanna connect them wrong...help..i want my heater back...
Never seen that done before. One day i may try to install the AC back into my Trans am. Very informative thanks! How you learn all this are you a mechanic?
Just did my heater core last oct. 87 monte ss.. I got a open air. Cleaner like yours but every time I put it on and I got t is vacuum lines that run from the carb in the old air cleaner i plug them. And my car runs like shit.. I don't have any other lines to plug cause I got long tube headers put in and got rid of shit I didn't need.. My car is very well taken care of just broke 99,000 engine never beat up on.. Got a elderbrock intake manifold hedmen headers long tubes and true duals into flows now bout to put comp cam with lifters push rods springs and double sprocket timing chain heavy duty high performance..
Unfortunately my cover broke into many pieces. Do you have any ideas on where I can get an OEM or aftermarket replacement? I would think an aftermarket parts manufacturer would have seen the value in producing a 2-piece cover so the piece caulked to the firewall wouldn't need to be removed.
Great information. I have one question. I noticed in top of the heater coil that a ground wire (green) was there. Where is it grounded too. Seconded I took my box out 3 months ago to clean, new evap, and heater core. I sealed it up yesterday but I know I didn’t place that ground back on there. Is it another location to ground the system (box)? Need a response please. Thanks,
I recently purchased an 87 Camino with a ZZ4 350 crate engine. When the engine was installed they evidently hit the heater/ ac box cover and broke a piece out it behind the core. Does anyone sell a replacement, new or used? Your videos are very helpful.

Whats the best aftermarket brand heater core to get for a 87 cutlass supreme? I see autozone and oriley have them but Im not sure on how long they will last
D'ANGELO the problem I had with O'Reilly's and AutoZone heater cores in my 78 Regals were the heater core was a 3/8 of an inch to tall and my top cover couldn't bolt back down tight because of it. I had to put the original back in. I was going to change it too since I was replacing everything dealing with the a/c with brand new parts. I'm going with RockAuto if mine starts to leak. Really I have no choice because of the height issue with the other parts houses heater cores.
How do I put the new open Air cleaner on With out it running like shit.. Running hard.. I got two. Nice ones.. Eldebrock chrome and a nice like flat black one that say chevy in red with the bow tie as the nut.. Help brother please.. Thanks sorry for the big ass comments lol..
Viarella You just need to plug off the unused lines that go from your current air cleaner to the carb etc so you don't cause any vacuum leaks when you unhook it all.
Would you be able to do a video on troubleshooting the vacuum system that controls the vent doors for the AC/heat system? I have a 1984 El Camino and the air will only blow out at the floor. I believe I may be missing a vacuum reservoir under the hood that the plastic lines should be hooked to. However, I'm not exactly sure how the vacuum lines should be hooked up.
Hi,, just found ya'lls vids and fb too.. Just bought an 88 olds cutlass supreme classic brougham last week from Ohio. One owner only 17,000 miles. Just arrived yesterday, took it out for a little 5 mile drive and parked it in (heated) garage and looked underneath car 2 hrs later and have a nice 1/2 a cup of anti-freeze on the floor.... its dripping from near the right front wheel near where the cat converter attaches up to engine... Ive ruled out leaky fill jug,, ruled out radiator, ruled out visual hoses not leaking,,, so my question is heater core? I put the heater on in idle got it to temp and had windows up, the windows fogged up and did smell a smig like anti freeze inside,, faint smell,,, wouldnt it be leaking in the floorboard on the passenger side??? which its not..... thanks for any help,, df.
@@ClassicGBodyGarage yep,, i bypassed the heater core and running now with no heat which really is not a problem as I dont drive it in 40 degrees or below or rain,,, ha ha,,,, bypassing core solved the problem for now,, thanks
@@ClassicGBodyGarage Nobody seems to! My Mom has a 95 Cutlass Supreme with 80,000 miles on it and it is like brand new. She had the AC replaced last year and now the evaporator needs replacing. My brother is a mechanic and can fix it, but he is just trying to find a video or someone who can help him out a little before he has to take out the whole dash.
I recently bought an 85 Olds Toronado as my first car earlier in February. I have a battery drain issue. I've done many checks from the alternator to fuses to all the electrical appliances on the dash. Haven't found a single thing that could be the cause. I could use some help. Also I'm trying to remove my heater core without having to ripping off the entire dash. Any tips?

Great video i learned alot Thanks. I have a 84 monte carlo ls i put a 350 in it what all wires work the heater core ?
There are no wires that work the heater core itself. Wires will run the fan but hard plastic vacuum lines will run the vents in the dash.

Do you use the window butyl tape all around the box or just up against the firewall where the screen goes
Use it anywhere its needed. Top of box, screen etc.

Ground wire goes from the heater core bracket to the firewall. The ground wire must be on the heater core somehow.

I have an 83 cutlass....is the heater core in the same location as the one on this video???
Hi do y'all have a video on how to put the vacuum hoses back in their proper place on an 86 olds cutlass that has a 307v8??
Mark Mullen You can look up the emissions diagram on line.
3M Strip Calk works well for this too. It's a smaller diameter. The butyl tape can be kinda thick to compress at times.
Is it common for the hvac box seal that is inside cab to leak? Is there away to re seal without removing entire box
Yes it is common and you can use RTV if you want but still not the proper fix.
@@ClassicGBodyGarage thanks i already starter rippi g it apart. Want to do it correctly ONE TIME
All done. Box out fender and hood back on. Just waiting on block off plate. Awsome videos
thank you
Whats the best aftermarket brand heater core to get for a 87 cutlass supreme? I see autozone and oriley have them but Im not sure on how long they will last
Buy the top quality through RockAuto
D'ANGELO the problem I had with O'Reilly's and AutoZone heater cores in my 78 Regals were the heater core was a 3/8 of an inch to tall and my top cover couldn't bolt back down tight because of it. I had to put the original back in. I was going to change it too since I was replacing everything dealing with the a/c with brand new parts. I'm going with RockAuto if mine starts to leak. Really I have no choice because of the height issue with the other parts houses heater cores.
How do I put the new open Air cleaner on With out it running like shit.. Running hard.. I got two. Nice ones.. Eldebrock chrome and a nice like flat black one that say chevy in red with the bow tie as the nut.. Help brother please.. Thanks sorry for the big ass comments lol..
Viarella You just need to plug off the unused lines that go from your current air cleaner to the carb etc so you don't cause any vacuum leaks when you unhook it all.
Is there a difference between driver and passenger side wiper arms?
yes
Would you be able to do a video on troubleshooting the vacuum system that controls the vent doors for the AC/heat system? I have a 1984 El Camino and the air will only blow out at the floor. I believe I may be missing a vacuum reservoir under the hood that the plastic lines should be hooked to. However, I'm not exactly sure how the vacuum lines should be hooked up.
robofuzz Yeah will do. I have been asked that a few times. Thanks for watching.
Classic G-Body Garage Thanks! I enjoy your videos and they've been very helpful with working on our El Camino!
+Alitas de Bufalo Will make it happen!
I really need this video as well. I have the same problem and heat isn't that hot.
I replaced the blower motor and relays. Still did not fix the problem.
Hi,, just found ya'lls vids and fb too.. Just bought an 88 olds cutlass supreme classic brougham last week from Ohio. One owner only 17,000 miles. Just arrived yesterday, took it out for a little 5 mile drive and parked it in (heated) garage and looked underneath car 2 hrs later and have a nice 1/2 a cup of anti-freeze on the floor.... its dripping from near the right front wheel near where the cat converter attaches up to engine... Ive ruled out leaky fill jug,, ruled out radiator, ruled out visual hoses not leaking,,, so my question is heater core? I put the heater on in idle got it to temp and had windows up, the windows fogged up and did smell a smig like anti freeze inside,, faint smell,,, wouldnt it be leaking in the floorboard on the passenger side??? which its not..... thanks for any help,, df.
Not all heater cores leak inside the car. All signs point to a bad core.
@@ClassicGBodyGarage yep,, i bypassed the heater core and running now with no heat which really is not a problem as I dont drive it in 40 degrees or below or rain,,, ha ha,,,, bypassing core solved the problem for now,, thanks
Ok, so how do I replace the evaporator on a 95 Old Cutlass Supreme?? Can't find a video anywhere.
I don't know anything about a 95
@@ClassicGBodyGarage Nobody seems to! My Mom has a 95 Cutlass Supreme with 80,000 miles on it and it is like brand new. She had the AC replaced last year and now the evaporator needs replacing. My brother is a mechanic and can fix it, but he is just trying to find a video or someone who can help him out a little before he has to take out the whole dash.
Is it the same process on a 88 G-Body SS
All Gbodys
I recently bought an 85 Olds Toronado as my first car earlier in February. I have a battery drain issue. I've done many checks from the alternator to fuses to all the electrical appliances on the dash. Haven't found a single thing that could be the cause. I could use some help. Also I'm trying to remove my heater core without having to ripping off the entire dash. Any tips?
Check glove box light that was my drain
what about the A body 1977 cutlass, does that one year make a difference lol?
