4. SUPERChARGER ASSEMBLy PREPARATION

AND INSTALLATION, cont'd

Remove the four (4) previously-loosened water

pump pulley screws and remove the OEM water

pump pulley. Install the included replacement

water pump pulley in its place and secure with the

OEM screws. It will be easier to fully tighten the

screws after the belt is installed below.

Align the 6-rib drive belt according to the diagram

shown at the end of this section. The belt routing

is almost identical to the OEM routing with the

exception of the portion that passes between the

water pump pulley and crankshaft pulley to drive

the supercharger. Ensure that the belt routes

smoothly over the supercharger pulley and all of

the new idler pulleys as well as the OEM engine

accessories.

Use a 15mm wrench to rotate the OEM belt ten-

sioner counter-clockwise and install the belt.

Depending on pulley size, it may be necessary to

adjust the location of the ribbed supercharger idler

pulley to achieve proper belt tension. Ensure that

the belt wraps smoothly around each of the pul-

leys and that all ribbed pulleys are properly

engaging the belt's ribs.

Locate the supplied 1.25” black anodized alumi-

num throttle body spacer. Install the included

large O-ring into the groove in the spacer -- this

O-ring seals against the throttle body, and the

smooth side of the spacer seals against the OEM

O-ring in the intake manifold. Reinstall the throttle

body,

rotated 180° from its original orientation

(upside-down), using this spacer, the four (4)

included M6 x 80mm socket head cap screws,

and four (4) included 6mm washers. Ensure that

both O-ring seals stay in place. The OEM evapo-

rative emissions tube connecting to the solenoid

on the intake manifold just behind the throttle

body will have to be slightly bent. (See Fig. 4R)

Carefully snip the strip of tape securing the throt-

tle body electrical harness to the connector hous-

ing. Reconnect the connector to the throttle body.

(See Fig. 4R)

Route the large wiring harness near the passen-

ger side valve cover, throttle body electrical har-

ness, and any other items away from moving

parts and sharp edges and secure.
