Heater Core Foam?
i have my truck schedualed for getting the heater core replaced in a few days...and the core i bought came with no foam insulation...so now im a bit worried. looking everywhere...every picture has different sizes of foam around the edgs of the cores...has anyone done this? id like to know what you used and the tickness of the foam you used (if possible) also reading...o rings need to be replaced as well? of course i dont have those either. so sizes for those would be needed as well. i drive a 01 dodge ram 1500. any help would be greatly appreciated.
