Alright, sounds good, thanks again everyone! The car it is going into had pretty much solid rust as coolant, so the heater core is dead as a door nail. I have a brand new bmw e30 heater core I may try to frankinstall.. we shall see. If I end up not being able to salvage any kind of heater core, do you guys think I could just cap the feed and return? Hopefully the small amount of cooling that it might provide is not crucial..
