Firewall question.

[OldRedFord]

What can I do to better seal where the heater core pipes come through the firewall?

[BobbyFord]

Take a round, thick piece of material, such as rubber, with a 5/8" hole in the center and slide it onto the heater core pipes before you put the hoses on.

ford made regular rubber seals to go around the hose holes. i dont know if you can get some from a vendor or just walk into the parts store and buy something like that. they would be similar to a protector for for electric wiring going through a piece of metal like a firewall.

Hey Tim!

I haven't tried this stuff, but you could give it a whirl. It looks easy to apply, at least.

When I worked for an AMC/Jeep dealer back in the early 70's, we used a lot of that stuff for sealing around cables, hoses, etc. It works pretty good, and is easy to use.

I would research what Fordman said about the grommets. That would provide protection against chafing of the heater hoses, where the caulk would not.

The seals are available from LMC.
