Title: Sealant for A/C Box on Firewall
Post by: ehjorten on January 22, 2011, 05:58:00 pm

Anybody know what kind of sealant the factory used to seal the a/c box to the firewall and around the tubes of the evaporator coming out of the box?  Or a better modern day equivalent?

I used a roll of foam tape in between the firewall and ac box, but I have the ac delete box. as far as the tubes, use butyl tape.
