Tools Required

J 43094 Spark Plug Boot Puller

1. Remove the mounting nuts retaining the injector sight shield.
2. Lift the injector sight shield off the mounting studs by lifting at the front (4) of the cover.



3. Disconnect the electrical connector from the ignition control module.
4. Remove the 7 bolts (2) retaining the ignition cassette to the cam cover.




Important: Do not insert the screwdriver far enough to tear the perimeter seal on the cassette.

5. Gently pry the cassette (2) away from the cam cover (3) using a screwdriver. Protect finished surfaces from scratches with a shop cloth. Pry a small amount in several locations around the edge of the cassette in order to lift the assembly as evenly as possible.

Important: When servicing the ignition system components, use the following recommended procedures:

1. Install the ignition control module (2) on the ignition coils.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

2. Install the ignition control module retaining screws (1).

Tighten
Tighten the retaining screws to 1.1 N·m (10 lb in).
