Installation Procedure

WARNING: This page is about a different car, the 2004 Pontiac Grand Prix. However, it is still accessible from the selected car via links, so may be relevant.

IMPORTANT: The new SOPS comes with a position lock pin that is installed on top of the SOPS. This locks the timing gears in place. Do not remove this pin until after you have installed the SOPS and the actuator.

Keeping the position lock pin in the new SOPS, position the SOPS switch over the drive cables and press down.
If the SOPS does not slide into position, the ridges on the drive cable housings will not go into the grooves on the back of the SOPS. Lift each cable into the SOPS, and press down on the SOPS assembly.
