J 43094 Spark Plug Boot Puller

REMOVAL PROCEDURE




1. Remove the fuel injector sight shield.
2. Disconnect the ignition control module electrical connector.
3. Remove the 7 bolts (2) retaining the ignition cassette to the cam cover.




4. 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. DO NOT insert the screwdriver far enough to tear the perimeter seal on the cassette.
5. Lift the cassette straight up off the spark plugs.
