A. Clean the front of the driver side head of
debris.
B. Slide the supplied M10 x 25mm screw and
washer into the mounting bracket hole behind
where the power steering pump is to mount.
Install the 180° end of the supplied 5/8" mold-
ed hose through the two holes in the mount-
ing bracket. Trim the straight section for best
fit (See Fig. 8-a). Install the supplied #8 hose
clamp over hose and install the power steer-
ing pump onto the supercharger mounting
bracket using the original hardware and sup-
port plate. Tighten hose clamp. Gently secure
hose away from the pulley using a zip tie
routed through the two holes in the mounting
bracket. (See Fig. 8-b.)
C. Install the supplied gilmer (toothed) belt
around the pulley on the mounting bracket
assembly. The belt can not be installed after
the mounting bracket is installed
D. Install the supplied 3/8-16 x 2" screws and
washers in the middle two supercharger
mounting bolt positions. These bolts can’t be
installed after mounting bracket is installed
onto the engine. (See Fig. 8-b.)
E. Bolt the supercharger mounting bracket to
head with previously installed M10 x 25 mm,
the supplied M10 x 35 mm and one of the
factory power steering pump bracket bolts
(Should be about 75 mm long). This is very
difficult with the power steering pump
installed. Try starting the two upper bolts very
loosely so that the mounting bracket is still
free to move. Start the 25 mm bolt by hand if
possible or with a thin (16 mm) open end
wrench.
F. Make sure that mounting bracket is seated
directly on machined surface on head, that no
wires are pinched and that the power steering
hose is routed in the recessed portion of the
mounting bracket. (See Figs. 8-c, 8-d.)
G. Tighten the three mounting bolts in steps to
37 ft·lb (50 N·m).
H. Attach the factory power steering high pres-
sure line to the pump and tighten. Install the
power steering pump pulley. Verify that the
NOTE: The mounting bracket and power steering pump can be
installed in the manner in which the stock mounting
bracket was removed. The following steps apply to a
2002 ZO6, which has the ABS module directly in front of
the power steering pump. For vehicles with the ABS mod-
ule mounted elsewhere, it may be easier to leave the
power steering pump connected to the power steering
hose but loose until after the mounting bracket is
installed.
