6. Aftercooler Core

A. Wrap the aftercooler core with the supplied

heat blanket. Install the two supplied 1/2” NPT
x 3/4” straight barb fittings into the aftercooler
core using a small amount of pipe sealant onto
the threads.

B. Attach the supplied 90

° long rubber elbows to

the water fittings (the short leg of each elbow
must be trimmed 1-1/4" and be installed with
the short leg on the core side) on the core.
Slide a hose union into the open ends of each
elbow (see photo - 9). Connect the previously
cut 48" and 90" sections of hose to the proper
hose unions (refer to the Hose/Component
Schematic). Secure all hose connections with
the supplied nylon clamps.

C. Remove the two center driver’s side valve cover

bolts temporarily. Place the supplied aftercooler
core support onto the center of the valve cover
and secure with the factory valve cover bolts
(see photo - 10).

D. Place the aftercooler core (snaps down) onto

the aftercooler core support, in-between the
power brake booster and the intake manifold
(see photo - 11), while at the same time routing
the water lines around the rear of the power
brake booster toward the driver side corner of
the engine compartment. It may be necessary
to lightly bend the brake line cluster on the
shock tower for core clearance. Also, the
factory fuel lines must be routed down along
the side of the valve cover. Make sure that the
routing of the water lines allows for a smooth,
non-kinked path.

E. Route the water hose coming from the driver

side fitting on the core, to the previously
mounted 3/4” x 90

° rubber hose on top of the

water tank (there should already be a brass
hose union attached here). Connect the hose
to the tank at this point. Trim hose length if
necessary. Do not yet secure with the supplied
plastic clamp; the hose must be removed in
