Ignition Cable: Service and Repair

REMOVAL




CAUTION: Do not pull on the spark plug wire as it may separate from the spark plug wire connector inside the spark plug wire boot.




1. When removing spark plug wires from spark plugs, use a spark plug wire remover. Grasp and twist the spark plug wire boot back and forth on the spark plug insulator to release the connector.



2. Disconnect the spark plug wire from the ignition coil by squeezing the locking tabs and twisting while pulling upward.
3. Open spark plug wire separators and remove spark plug wire.

INSTALLATION

CAUTION
- Proper installation of spark plug wires is critical to vehicle operation. If one spark plug wire is not properly installed on spark plug or ignition coil, both spark plugs connected to that segment of the ignition coil may not fire under load.

NOTE
- when a spark plug wire is removed for any reason from a spark plug or ignition coil, or a new spark plug wire is installed, Silicone Brake Caliper Grease or Dielectric Compound must be applied to the spark plug wire boot prior to insulation.

1. Use a small, clean tool to coat the entire interior surface of the boot with Silicone Brake Caliper or Grease Dielectric Compound.
2. Squeeze locking tabs on coil retainer and push down on boot with a slight side-to-side twist to connect spark plug wire set on the ignition coils. Each of the terminals is identified on the ignition coils. The firing order of each coil is 1-3-4-2. Check that each of the spark plug wire is fully seated and both locking tabs are engaged.
3. Remove the ignition wire separator from the spark plug wire set and reinstall it in the same relative position on the new set.
4. Route the spark plug wire set toward the spark plugs.
5. Connect each spark plug wire set on the proper spark plug.
