Ignition Cable: Service and Repair
REMOVAL
Fig.55 5.7L Spark Plug Cable Routing
Spark plug cables on this engine are paired on cylinders 1/6, 2/3, 4/7 and 5/8. Before removing or disconnecting any spark plug cables, note their
original position. Remove cables one-at-a-time. To prevent ignition crossfire, spark plug cables MUST be placed in cable tray (routing loom) into
their original position. The cable retention clips must also be securly locked.
Before installing spark plug cables to either the spark plugs or coils, apply dielectric grease to inside of boots.
If cable tray removal is necessary, release the 4 tray-to-manifold retention clips.
Refer to Spark Plug Cable Removal for information.
INSTALLATION
Install cables into the proper engine cylinder firing order sequence. Refer to Specifications.
When replacing the spark plug and coil cables, route the cables correctly and secure them in the proper retainers. Failure to route the cables properly
may cause the radio to reproduce ignition noise. It could also cause cross-ignition of the plugs, or, may short-circuit the cables to ground.
When installing new cables, make sure a positive connection is made. A snap should be felt when a good connection is made between the plug cable
and the distributor cap tower.
