There ain't no best way nor easy way. The only model avialble requires more cussin.

recently, I took out the inner fender-well on a 70 camino for exhaust manifold replacement without removing the fender. While peering up under the fender, I could see the blower motor and the nuts to the heater core cover. I think, although i've not done this, that the easiest way to change the heater core would be to remove the inner fender well; it's about 9 or 12 bolts, but first take out the battery. I believe once the nuts are removed from the heater core cover in the engine compartment, then the heater core enclosure could be removed on the inside of the car and the core then replaced (drain and disconnect hoses first no doubt - oh yea, remove rim).

Ok, granted I've not done this yet, but maybe someone could agree or disagree with my theory.

You didn't say if you had Air or not. If you have Air, It'll take you about an hour. without Air, about a half hour. All work is done without removing the inner fender. (unless you need to remove the AC box for other reasons.) Core without Air, about $20. with Air about $35 as I recall. I changed two of my Elcamino 5 th gen this past year, one with Air, one without. For more info on the 'how to's ', check out the 'Search' here on the site. Hope this helps Bob

Try typing "heater box" into the search engine

On a 5th Gen do not remove the fenderwell. The job is pretty straightforward and consists of removing the top part of the HVAC box.
Some tips: be careful about prying off the top of the HVAC box because there are some screws that are hidden and hard to find. Three large nuts that hold the top to the firewall are accessed by removing the wiper arms and lower windshield trim. Good luck.

Hmmm. I guess my theory is all wet, but wait, is it true for 70 that the inner well does not have to be removed to get to the nuts holding the cover of the heatercore. I ask because I can't see some of the nuts until I remove the inner fender well.

Oh yea, the reason I removed the inner fenders to replace the exhaust manifold was because I wanted to repaint the sides of the engine without the manifolds attached, and it was far easier without the inner fenderwells.

Winter is a great time to remove those inner fender wells and clean them up and repaint. If you've got them out, now is the time to do so. You won't believe the difference it makes in your appearance. You can see the before and after in my photo album on the third page. A real low cost improvement, for sure.

Your OK 396driver, the original post here was for a fifth gen. and for those, you don't need to pull the inner fender to replace the core. Only if your going to pull the whole AC box. Hope this clears that up. Bob

That's right. It's all been discussed here previously. Biggist tip I can give is: If you're absolutely positive you have removed all the screws, and the top still won't budge, don't try to pry the top off, find the rest of the screws holding it down. BTDT Good luck.
