C. Water Cooler Installation
1.
Using the supplied hardware, loosely attach
one supplied bracket to each side of the water
cooler as per Fig. 11-h. Using sealant, insert the
90° fittings into the inlet and outlet of the water
cooler and point them towards the passenger’s
side of the vehicle. (See Fig. 11-i.)
2.
With water cooler inlet and outlet pointed
up, insert bolts through the brackets into the
existing holes at the lowest mounting point in
the vehicle’s radiator core support.
3.
Tighten the bolts securing the bracket to the
water cooler. Tighten the bolts securing the
brackets to the core support.
4.
Using the brackets as a guide, drill a 1/4” hole
on each side of the water cooler. Insert the
supplied 1/4” bolts through the brackets and
into core support on each side of the water
cooler.
5.
Connect the outlet of the water pump to the far
side of the water cooler with 3/4” hose. Clamp
each end.
6.
Route the 3/4” hose from the remaining fitting
on the water cooler, in front of the radiator, next
to the passenger side upper engine mount,
under the hoses and wiring and next to the
throttle body.
D. Aftercooler Installation
1.
Locate the coolant hose that connects to the
throttle body. Remove the metal tube assembly
and all connected hoses. Install the supplied
1/4” hose and clamps between the thermostat
housing and the throttle body.
2.
Using sealant, install the supplied 90° fitting into
the 1/2” NPT hole in the aftercooler core near-
est the air outlet. Install the supplied straight
fitting in the remaining hole. Connect the hose
previously routed near the throttle body, to the
90° fitting installed in the aftercooler.
3.
Install the supplied 150° hose elbow onto the
straight fitting on the aftercooler so that the
free end will be routed near the distributor.
CAUTION:
In the following step, use
extreme care when drilling
through the core support. If the
drill bit slips or goes through
the hole too far it will damage
the radiator or the A/C con-
