1. PREPARATION/REMOVAL

A. Disconnect the negative battery cable.
B. Remove all of the components that lead to the

throttle body including the mass air flow (MAF)
sensor, air filter assembly and rubber bellows.
Separate the MAF sensor from the air filter
assembly and set aside.

C. Remove the air temperature sensor from the inlet

duct.

D. Remove the factory accessory drive belt.
E. It is necessary to remove the refrigerant from

the air conditioning system. This should be
performed by a qualified technician using a
refrigerant recycling system. Releasing refrigerant
into the atmosphere is environmentally
irresponsible and should be avoided.

Unplug the A/C compressor and the A/C line

electrical connectors. Using a springlock
disconnect tool, disconnect both ends of the A/C
line that runs from the condensor to the firewall-
mounted canister. Remove the screw mounting
the A/C line junction block to the compressor and
remove the line from the vehicle.

G. Remove the A/C compressor from the factory

bracket.

H. Using a T55 Torx bit, remove the belt tensioner

from the factory bracket.

Remove the factory A/C bracket including

mounting hardware from the engine.

(1999-2000 Models Only)

Remove (if equipped) the exhaust gas recirculation

(EGR) tube (one end connects to the passenger
side exhaust manifold). Note the orientation of
the pressure differential sensor.

K. Remove the passenger side front kick panel from

the interior of the vehicle. Remove the sound
deadening material (if any) that is covering the
ECM. Remove the plastic ECM hold-bracket.

Using the 10mm socket or wrench, remove the

harness and plug from the ECM (as you loosen
the screw, the connector will slowly release).
Remove the ECM from the vehicle.

M. Contact the Vortech Sevice Department for a

return authorization number. Send both ECM
and supplied credit tag to Vortech using the
enclosed shipping box.
