Removal (3.5L)

WARNING: This page is about a different car, the 2002 Oldsmobile Intrigue and 2002 Oldsmobile Aurora. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: The ignition coils/ignition control module assembly is also referred to as an ignition cassette.

Turn ignition off. Remove mounting the 2 mounting nuts from the injector sight shield (top engine cover). Lift the injector sight shield off the mounting studs by lifting at the front of the cover. Disconnect the electrical connector from the Ignition Control Module (ICM). See Figure.
Remove 7 bolts retaining the ignition cassette to the valve cover. Gently pry the cassette away from the valve cover using a screwdriver. Protect finished surfaces from scratches with a shop cloth. Pry a small amount in several locations around the edge of the ignition cassette in order to lift the assembly as evenly as possible.
Do not insert the screwdriver far enough to tear the perimeter seal on the cassette. Lift the cassette straight up off the spark plugs. Remove the secondary boots from the spark plugs or the ignition coils using a twisting motion to break the seal. Do not use pliers, screwdrivers or any unauthorized tool to remove the boots. Remove the cover from the ignition coils. Remove the ICM screws. Remove the ICM.
