CHARGE COOLER INSTALLATION

A. Remove the screw from the front of the pas-

senger side head. Remove the 10mm nut

located between the middle coil packs on the

passenger side valve cover, below the white

electrical connector. (See Figs. 8-a, 8-b.)

B. Install the charge air cooler support bracket

using the fasteners supplied. (See Figs. 8-a,

8-b.) Apply adhesive foam to the top of the

support bracket where the charge air cooler

rests. Make sure all hoses and wires are

clear from the bracket edges.

FROM BRACKET

C. Slightly bend both the transmission and

engine oil dipsticks up and away to give

clearance for the charge air cooler.

D. Install the nickel plated 1/2"NPT x 3/4 90°

and straight brass fittings into the charge air

cooler using thread sealant on the threads.

(See Fig. 8-d.)

E. Install a 20-inch piece of 3/4 hose to the 90°

fitting and secure with a nylon clamp.

F. Attach the long 90° formed hose to the

straight barbed fitting on the charge cooler.

(See Fig 8-c).

G. Set the charge air cooler on the support with

the 90° brass fitting in the upper left corner

facing toward the passenger’s side. Using the

2-3/4" sleeves and #44 hose clamps, connect

discharge tube “A” to the discharge of the

supercharger and to the inlet of the charge air

cooler (See Fig 8-e).

NOTE: On later model trucks there will be no EGR assembly. Use the

supplied 10mm x 1.5" screw, washer and .975" spacer in its

place. (See Fig. 8-a.)
