72 Heater core replacement

Hello I'm new to the forum,

I have a 1972 Chevelle with a bad heater core. Are there any threads with advice or instructions on how to take on this project. Photos would help. Thanks

Not really, it pretty much sucks. You are better off doing a google search that brings you right back here. Maybe it's just me, but I have little luck finding stuff on this site using their search function.

A no air car is pretty easy. A car with A/C is much harder.

You're just jealous because you can't hear the voices!

Re: 72 Heater core replacement

I just pulled mine out of my ‘68. Basically the same. Unbolt right inner fender so you can drop it enough to get your arm in there. Remove glove box. Disconnect control cables from the heater box. Remove all of the nuts & screws from the engine compartment side. The whole contraption drops down onto the passenger floor. You’ll see how the core is held by a clip with two screws on one side. Replace & reverse for assembly. If you’re good, you can knock it out in about four hours.

Eek! You’re right. I was assuming a heat-only car.

Yes, I agree with you, I was thinking more along the lines of the OP signing up for this site solely to ask a question that's been covered plenty of times, and if he would have just taken the time to search (as you say on Google) he'd save us from having to spend time re-answering questions that we've already answered already before. I can't type and doing so is a hassle that I'm too old to endure.

Since he's posted twice, I assume he's here to mooch off Dean and not to contribute! Oops, that's not PC is it. Sorry.

Re: 72 Heater core replacement

Don't use aluminum. I'm not sure they even make the Chevelle heater core in aluminum anyhow but if they do don't use it. One nice thing about aluminum is when it springs a leak that aluminum hole patch up powder works real good with the aluminum core...

I used an aftermarket aluminum heater core in my 69 el Caminos home made heater system and it springs up a leak every spring lol.. Hey! spring! LOL!!

Buy a GM service manual. If you are inclined to go more advance get a GM Overhaul manual. There is even a Fisher Body Service manual. All with specific info for the given model year. Lots of information for the entire car. Lifetime references. I still have all of mine.
