A/C & Heater Hose
Installation (Cont.)
1.
2.
Connect two pieces of heater hose approximately 45 inches long to the heater hose fittings. Using a small
amount of white grease on the heater hose fittings to make slipping the hoses on easier, push the hoses past
the plane of the bracket (See Photo 5, below). NOTE: Be sure not to loosen the fitting connection nut
when pushing the hoses onto the barbed heater hose fittings. Hose clamps will be installed after the
evaporator is secured to the firewall, and the rubber boot and firewall ring have been installed.
Insulate the #10 A/C hose fitting at the evaporator with press tape, covering all metal as shown in Photo 6,
below.

1.
2.
3.
From the engine compartment, temporarily secure the firewall cover to the firewall using (2) 1/4-20 x 3/4”
bolts, (2) flat washers and (2) nuts with star washers (See Photo 1, below).
Mark and drill (2) 5/16” holes through the upper and lower passenger side mounting holes in the firewall
cover (See Photo 1, below).
Remove the firewall cover, and apply a bead of silicone to the back side of the firewall cover at the edge of
all seams and bolt holes (See Figure 1, below). Secure the firewall cover to the firewall using (4) 1/4-20 x
3/4” bolts, (4) 1/4” flat washers and (4) 1/4-20 nuts with star washers. NOTE: The remaining hole on the
firewall cover will be used to mount the evaporator unit (See Photo 1, below). Also note, paint will
not adhere to silicone.
