Locate the bottom left mounting hole on the firewall cover, and install a 1/4-20 x 3/4” bolt and a 1/4”
pushnut retainer (See Photo 1, below).
Apply a bead of silicone around the mating surface of the firewall cover, as shown in Photo 2, below.
Install the firewall cover onto the (2) 1/4-20 x 1 ½” studs, and secure it using (2) 1/4-20 nuts with star
washers (See Photo 3, below).
Install (3) 1/4-20 x 3/4” bolts into the remaining open mounting holes on the firewall cover and into the
evaporator firewall bracket (See Photo 4, below). NOTE: Do not tighten at this time.
Remove the (2) 1/4-20 nuts with star washers and the (2) 1/4-20 x 1 ½” studs from the firewall cover, and
replace them with (2) 1/4-20 x 3/4” bolts (See Photo 5, below).
Install (1) of the previously removed 1/4-20 nuts with star washers onto the bottom right firewall cover bolt
in the passenger compartment (See Photo 6, below).
Verify that the evaporator unit is level and square to the dash.
NOTE: To ensure proper drainage, it is
very important that the evaporator is level, both left-right and fore-aft. Check for level on the flat
portions of the case around the drain.
Tighten all of the mounting bolts at this time. NOTE: Tighten the bolts on the firewall first. Adjust the
evaporator dash bracket as needed, and then tighten the bolts on the evaporator unit. Silicone or
seam sealer may be applied around the outer edge of the firewall cover.
NOTE: To ensure a watertight seal between the passenger compartment and the exterior, for all
bolts passing through the firewall, Vintage Air recommends coating the threads with silicone prior
to installation.
