CRANK PINNING & OIL COOLER INSTALLATION
CRANK PINNING NOTE: Some of the following steps,
while not strictly related to installing the supercharger,
detail the process required for installing a lock pin between
the harmonic balancer and the crankshaft nose. The
factory design uses a press-on balancer that does not
include an anti-rotation mechanism to prevent the balancer
from loosening. The additional torque of the E-Force
system increases the likelihood of this occurring. Any
damage caused by failure to follow this procedure will not
be covered by the optional warranty. If you have already
had this procedure performed on your vehicle, skip steps
72-106 and 124-139.
OIL COOLER NOTE: Installation of oil cooler is explained
with in the crank pinning procedure as It is easiest to install
once the crank pinning procedure has been completed, but
before the steering rack and other parts are reinstalled.
If you have already had the crank pinning procedure
performed on your vehicle, then the Oil cooler installation
(Steps 107-123) can be performed after the supercharger
installation has been completed, albeit with a greater
degree of difficulty.
72. Use a hand siphon to drain the power steering fluid
reservoir.
73. Disconnect the alternator electrical connector.
74. Use a 13mm socket to remove alternator power wire.
75. Use a 15mm socket to remove the two alternator
support bolts, and then remove the alternator.
WARNING: With the wheels of the vehicle facing straight
ahead, secure the steering wheel with a steering column
anti-rotation pin, steering column lock or strap. Failure
to do so may result in damage to or a malfunction of the
airbag deployment system.
76. Use an 11mm socket and an extension bar to remove
the bolt securing the steering column to the rack then pull
the intermediate shaft off the gear. Do not attempt to turn
the steering wheel until this bolt has been reinstalled.
