Under dash insulation

[Dave K.]

There is a blanket of pink fiberglass insulation against the upper firewall inside the car above the heater box. Insulation appears to extend from the pasenger outer side to just beyond the wiper motor on the driver's side. While taking the four hex head screws out that attach the wiper motor to the firewall, some of this insulation was damaged. It actually covers over the motor and it appears my motor was never removed before. This insulation is 35 years old and easily tore as I moved it to get access to the motor screws. I'm assuming that it is there to thermally insulate the passenger compartment from engine heat? Should I be concerned about the insulation tears and try to repack the torn insulation back against the wiper motor after I refurbish it, maybe by using a spray on glue or something.

Thanks,

Lets see? 2002 less 35 = 1967. Can I assume we are talking about a 67? At any rate there is no Owens Corning pink fiberglass insulation in a midyear, so I would assume that it is not original stuff.

Wayne,

It's a 66 roadster. This insulation appears to be original. It's about 1 in. thick w/o a paper vapor barrier reinforcement.

Re: Under dash insulation

Dave, when I had occasion to pull the dash on my April built 66 I had brown colored fiberglass(?) insulation that was glued to the firewall. Since I am not anywhere close to being the original owner, I can only state that it APPEARED original. It came out in chunks and appeared very old and beat up.
Btw, I think Dr. Rebuild sells this stuff in his catalog. I am relying on memory here on that issue.

Gery/Wayne,

Wayne may be right. I'm going to check the AIM to see if there is any reference to original insulation installation under dash. My car's insulation was definitely pink, unless I'm color blind!

Re: Under dash insulation

Hi Dave
I just replaced the insulation on my 67 and it was like a felt ,yellowish in color and did not cover the wiper motor, It had cut-outs for the mouting screws and was secured by glue
