A. Place car on vehicle lift.

B. Raise hood and use appropriate fender covers for paint

protection.

C. Unpack the new accessory drive belt to let the “bends” relax. This

is best done in a warm room rather than a cold shop.

D. Locate the hose coming from the firewall that leads to the air filter

resonator system and disconnect at the first 90° fitting near the
firewall. Cap fitting with supplied 5/8” cap. See Fig. 2A.

E. Disconnect the opposite end at the resonator. Remove the entire

assembly from the vehicle, as it will no longer be used.

F. Disconnect the crankcase breather hose from the 90° plastic

fitting in the rubber air inlet duct.

G. Unplug the Mass Air Flow (MAF) connector from the MAF sensor

located on the air filter lid. Disconnect the rubber inlet duct from
the throttle and remove it with the air filter lid and set aside.
Unfasten the air filter box at the three mounts and remove.
Remove and save the rubber cushion mount assemblies and
hardware for reinstallation in a later step. The duct and other air
filter box components will not be reused.

H. Remove the plastic belt covers from both the alternator and the

A/C compressor. Set aside covers and mounting hardware for
re-installation in a future step.

I. De-tension the belt tensioner and remove the accessory drive belt.

The belt will not be used with the supercharger system.
