Oh, yea, the heater core is proly about cost of an oil & filter change plus a bit more. Inexpensive part and the "while we're here" rule is in play now. Just test the damn thing before you install it to check for leaks. The foam could probably be bought at the hardware store in the HVAC section. You know those bootleg foam filter blanks, 2' x1' x 1'' thick stuff they sell it as a sheet and you cut it to fit your needs. Or if it's strips, you can hi-jack the install kit from a sleeve A/C unit. I have to confess that I don't know what the foam looks like. If I could see it I can probably make a determination of where to get some as I'm sure GM don't sell it at the parts department. I'll go look in my 90's FSM and see if I can figure an answer for you.

Here is a close-up picture of the foam on the heater-core, looks like it's approximately 1/4" thick. How would I get the new core pressure tested? Are even new cores bad right out of the box very often?
