Heater Core Seal

[cliffyp]

I've had my heater core out for a while, it was leaking and I don't need heat. I'm tired of the extra noise coming through the open holes on the firewall, so I've finally gotten around to replacing it. Local parts store had the core, but nobody knows anything about the seal.

The -20 lists part # 6273325

I searched online and the places that came up all said, "not available".

Does anybody know where I can find the seal, know an alternate part number that the parts stores might have, or is there another option if I can't locate the seal?

I used some camper seal from "Frost King". It has stick'um on one side and just trim it with a razor knife when mounted.

Did you just apply it to the firewall, or did you wrap it around the inlet & outlet pipes of the core?

I stuck it on the heater box itself. The original stuff is a soft putty like stuff that seals around the cores inlet and outlet pipes and heater box it self. If you can find that stuff that would be the thing to use. maybe the dealer..?? Good luck!!

I put some around the holes on the firewall and then wrapped the inlet an outlet pipes. It seems to work well, thanks for the suggestion. It came in a big roll, so I might go back and put some on the box itself.
