Ok, its my turn to do the heater core. I used a GM core last time I did it in 2000. Any suggstions for a good non-chinese one? Thanks all

Dealership or any AC DELCO part. And test it prior to putting it in to ensure it is not a leaker, as it has probably been sitting on the shelf for a while. Just my 2 cents.

Mine came from NAPA probably 7-8 years ago. (knocking on wood)

I picked up one from my local AC Delco store two years ago when I did that job on my '88 IROC-Z.

I bought mine at Oreillys last week and no leaks yet. I followed a write up on here and just removed the ECM, Support brace and heater door actuator. I was done in about 2 hours. Top housing bolts on the housing are a pain in the rear but you can get to them. GL

couple months ago, i checked my local chevy dealer for a 84-96 GM/delco heater core replacement, and they indicated it was discontinued. went to NAPA for a new core. like most everything else, it's probably made in china.

Yup.
There is a misconception that AC-Delco is GM. It is not. Ac-Delco is a re-boxing company, and does not make any parts.
They may make their boxes, but I doubt that too.

Thanks for that info. My guess they all come from china. Hey Pete, she has GM as manufacture. Probably china?

Mike,
I don't know where Proliance is made now but they use to be a GM supplier back a few years and were made in the USA..Thepartsladi usually had good stuff, that is probably your best bet...WW

Actually, most are made in Mexico. NAPA, CarQuest, and O'Rielly's all came from the same place when I had to get one lately. Pretty hard to buy American anymore, Mexico seems to the closest you can get.

Got my "new" heater core at Advanced (says "made in Mexico" on the box....not sure if this marking is for the box or the core though) for ~$30.....it is still sitting on the shelf in my garage......I'm waiting to see if it will install itself

"Harrison" used to make the heater core for the corvette.

I recommend that you test the new unit before installing. You can cut a thin bicycle tube and clamp it to the inlet and outlet and then inflate to about 10 psi. You might need to use a sleeve -- use whatever works. One of our mates installed a leaky core -- I would have been upset! This is not a job that you want to do twice. Hold everything underwater and under pressure to insure that any leaks are coming from the clamp fittings and not from the core. I also got pleasure from testing the core I removed to verify that it was at fault.

The result has been outstanding. There was a point in the process when I benefited from employing my son's smaller hands and arms. My best advice is to walk away from the project whenever you become irritated. I did it in 3 or 4 sessions over a weekend and, while not enjoying it, did not mind it all that much.
