As you know, the heater motor penetrates through the firewall and is visible from inside the engine compartment. My question... is there supposed to be a doughnut-shaped gasket or a housing of some sort that fits around the motor from the engine side? What is it made of and what does it look like. Where can I find one? I don't believe I've seen such a thing for sale by vendors or e-Bay. The motor is not centered in the firewall hole, and it looks a bit funny from the engine side. Thanks. | | | | | Joined: Sep 2001 Posts: 29,269 Bubba - Curmudgeon | | Bubba - Curmudgeon Joined: Sep 2001 Posts: 29,269 | There was a rubber seal attached to a metal ring that was screwed to the firewall. The motor projected through the seal. The motor should be close to centered in the hole in the dash. I think this has what you are looking for. I would call them to be sure that the large round seal is right. | | | | | Joined: Oct 2006 Posts: 9,671 'Bolter | | 'Bolter Joined: Oct 2006 Posts: 9,671 | Tim pointed out the gasket set if you want to order it. But I would just cut it out of a sheet of 1/16" rubber, maybe even an old inner tube. it is 4.75"od x 3.125"id or a tight fit to the motor. The metal retainer ring is 1/16"tk x 4.75"od x 3.75"id. it is retained by three clutch head screws from the engine side.
