1. PREPARATION/REMOVAL

A. Disconnect the negative cable at the battery.
B. Jack up the front of the vehicle and secure with jack

stands or use a lift.

C. Crank the engine over just until the arrow on the

crankshaft pulley points in the 6 o'clock position
(straight down).

D. Disconnect and set aside the anti-roll bar.
E. Drain the radiator completely by removing the radiator

cap and opening the petcock on the lower passenger's
side. Catch the coolant in a clean container to reuse
or dispose of properly.

Unplug the intake air temp sensor connector. Remove

the sensor from the intake elbow. Unplug the MAF
sensor located between the intake elbow and air filter.
(1993 models are not equipped with MAF meters.)
Remove the unit and set aside, taking care to protect
the wire elements inside. Remove the intake elbow/
resonator assembly. (On 1995-1997 models, the
5/32" hose must be removed from the inlet elbow.)
Using an upholstery fastener removal tool, remove the
entire air intake assembly including the air box and
filter.

G. Remove the factory air pump from the vehicle.
H. Unplug the ignition coil and ignition module

connections along with the attached ground wires and
set aside. Remove the coil and related hardware.

If the vehicle is equipped with an engine oil cooler,

remove the upper radiator hose assembly (driver's
side) from the radiator, water pump and intake
manifold. Set the complete assembly and clamps
aside for future reassembly.

Remove the 5/8" oil cooler hose from the water pump.

Remove the rubber 5/8" hose (on the bottom driver's
side of the radiator) that connects to the oil filter/cooler
assembly (do not remove the entire cooling line from
the vehicle).

K. Remove the accessory drive belt.
L. Remove the three (3) bolts that attach the harmonic

balancer to the crankshaft hub (do not remove the hub
or center bolt) and remove the balancer.

M. Label and disconnect the four (4) driver's side spark

plug wires from the distributor module.

N. Removing the driver's side radiator fan eases

supercharger mounting somewhat, but is not
necessary to complete installation.

NOTE: On models equipped with factory "ram air"

induction, remove the air inlet system entirely and
reinstall the fuel rail bolts originally securing the
air filter box.
