1. PREPARATION/REMOVAL
A. Disconnect the negative battery cable.
B. Remove the accessory drive belt.
C. Remove the plastic radiator cover and fasteners
located above the core support.
D. Remove the “question mark” shaped crankcase
vent hose with attached fittings from between
the passenger side valve cover and the air inlet.
Separate the plastic 5/8” to 3/4” adapter from
the hose and set aside for later use. Remove
the plastic tube running from the air inlet duct
to the idle air motor resonator and discard (the
plastic tube must be cut to separate it from the
resonator). Leave the resonator and U-shaped
rubber hose (connected to the upper intake) in
their factory location.
E. Remove all components that lead to the throttle
body including the rubber air inlet duct, mass air
flow (MAF) sensor, air filter assembly and intake
air temperature (IAT) sensor. Separate the MAF
and IAT sensors from the intake assembly and
set aside.
F. Drain approximately one gallon of coolant from
the radiator. Remove the upper and lower radiator
hoses from the steel water tube junction located
around the alternator. Disconnect both of the
water temperature sensor connectors located
on the water tube.
G. Remove the spark plug wire retaining bracket
and hardware located on top of the alternator.
Remove the steel water tube and retaining nuts
from the engine block.
H. Remove the two coolant temperature sensors
from the factory water tube and set aside.
NOTE: Although not necessary, temporarily
removing the strut tower brace allows
easier removal/installation of throttle
body ducting. Replace the brace when
supercharger and final inlet and dis-
charge ducting have been installed.
NOTE: ECM REMOVAL:
1. Remove the passenger side front kick
panel from the interior of the vehicle.
Remove the sound deadening mate-
rial (if any) that is covering the ECM.
Remove the plastic ECM hold-down
bracket.
2. Using a 10mm socket or wrench,
remove the harness and plug from
the ECM (as you loosen the bolt, the
connector will slowly release). Remove
the ECM from the vehicle.
3. Contact the Vortech Service De-
partment for a Return Authorization
Number. Send both ECM and supplied
credit tag to Vortech using the enclosed
shipping box.
