Start by turning off the ignition and taking off the fuel injector sight shield as the first step in
Spark Plug wire replacement. Start by disconnecting Spark Plug Wires labeled (2, 4, 6) from their corresponding spark plugs at the engine's back while making a note of their original positions. Use j 38491 Spark Plug boot removal tool to twist each Spark Plug boot 1/2 turn before removal before prying the heat shield gently up from the spark plugs. Repeat this Spark Plug wire removal procedure for the wires (1, 3, 5) positioned at the engine's front end. Note down the same wire positions and deploy the Spark Plug boot removal tool (J 38491) for this step. Pluck out the ignition wires from their coils while also pulling out each retaining clip that reaches from the
Ignition Coil to the engine's rear, front, and top points. Moving on to new Spark Plug wire installations only transfer boot heat shields with all Spark Plug wire retaining clips and conduit pieces. Follow these steps when adding new Spark Plug Wires to the engine: start installation with (1, 3, 5) at the front then move to (2, 4, 6) at the rear. After completing connections between ignition coils and spark plugs, replace the retaining clips. Reassemble first by connecting wires to spark plugs at the front then finish by connecting wires to spark plugs at the rear. The last step involves placing back the fuel injector sight shield.
