Evaporator Installation

Place the evaporator on the passenger side floorboard. Insert all hoses through the firewall hole (See Photo 1,
below).
OPTIONAL STEP:
Remove the heads from (2) 1/4-20 x 1 ¼” bolts (not supplied) and insert them into the
evaporator firewall bracket. These studs will help align the evaporator bracket with the holes in the firewall
during installation (See Photo 2, below).
Lift the evaporator unit up under the dashboard. Using a 1/4-20 x 1” bolt and 1/4” washer, install the bolt
through the firewall cover and into the weld nut on the evaporator bracket.
NOTE: Clear away the insulation
from the bolt holes on the firewall (See Photo 3, below).
Temporarily install a bolt into the top hole above
the hoses on the firewall, and into the evaporator bracket. This will help hold the bracket to the firewall while
the rubber boot is being installed over the hoses.
Insert all four hoses through the provided rubber boot, pushing the boot 4” to 6” from the firewall (See Photos
4 & 5, below).
NOTE: Soapy water may be used to ease installation of the hoses through the boot, but
ensure the A/C hoses are capped to prevent water from getting inside.
NOTE: To ensure a watertight seal between the passenger compartment and the vehicle exterior, for
all bolts passing through the firewall, Vintage Air recommends coating the threads with silicone prior
to installation.
