Firewall Cover Insulation
1.

3.
To apply insulation to the firewall cover, temporarily install the firewall cover onto the firewall using (2) 1/4-20
x 3/4” bolts and (2) 1/4-20 nuts with star washers (See Photo 1, below).
From the passenger compartment, trace the firewall opening onto the firewall cover (See Photo 2, below).
Remove the firewall cover, and apply insulation to the traced area (See Photo 3, below).
NOTE: For proper system operation, Vintage Air recommends using heat blocking insulation in the
area around the evaporator unit (firewall, kick panel, inner cowl, firewall covers). Due to tight
clearance for the evaporator unit between the firewall and dash, Vintage Air recommends an
insulation thickness of no more than 1/4”.
