Can anybody tell me where I can purchase a good quality aftermarket heater core. I am getting tired of replacing them. Thanks, Gary
I gave up on repro heater cores. My original Harrison heater core was rebuilt by R&R Radiator in Superior, Wisconsin. Used USA materials, and the workmanship is flawless. If you think the repro cores are equivilent, think again. The rebuilt unit weighs about 30% than a new repro unit.
Thats what I figured. Now I am stuck having to buy something. Does anybody have any suggustions on what to buy?? I won't hold you to it I promise!! Gary
Maybe you just had a run of bad luck with the repros. I bought one at the local Autozone for my Ford and it has lasted for years. Is there something about your engine or car (such as lots of vibration or super-high coolant temps) that is rough on heater cores? When I messed up the original core on my GS, I took it out and re-soldered it. Not a fun job, but it's holding up so far. If you have your original, you might try repairing it.
I think I just wasn't keeping up on the ph. Before I knew it I saw a big crusty area around the bottom hose where it connects to the front cover. When I took off the hose so I could clean it up I found half the aluminum nipple completely corroded away. Since then I got a huge leak in the heater core and just the other day I now have a leak in the radiator. I think I will just hang myself!! Gary
You can buy new ones through NAPA that are real good... I have never had any problems with NAPA heater cores... This one is for w/o ac, you can look through NAPA's webpage to look up the correct one, I wasn't sure what you have... http://napaonline.com/Catalog/CatalogItemDetail.aspx?R=NHS6603027_0237269038
Thanks, David. I want to order one of those for my 1969 GS 400 with no A/C. Is the part number you linked the right one for my car as well? I am having trouble using NAPA's car application software.
Yes that would be the same, 68 -72 Skylark and 68 - 69 Special That should be the one for you, Part # 6603027 http://napaonline.com/Catalog/CatalogItemDetail.aspx?R=NHS6603027_0237294952 I had to look it up as a Skylark as they don't list the heater core for the GS400, parts places are funny like that sometimes, you have to look it up as the base vehicle... I worked at a parts place for a few years and I still remember some of the tricks :TU:

Thanks again for that info, David. Now I will be able to drive without fear of the old core cracking and hot, greasy, smelly antifreeze leaking inside on to the new carpet.
Your welcome... I have to replace mine also, I've had it for a year or so now, I just don't feel like pulling the hood, fender and all that BS that go's with replacing it
I bought mine at Advance Auto. The joints look weak where the old one was leaking so I re-solder all the joint. No leaks yet.
