Ignition System: Service and Repair

Spark Plug Wire

Removing


Always turn the engine off and disconnect the battery prior to servicing the spark plug wires. Do not attempt to remove a spark plug wire while the motor is running. Failure to follow these directions may result in serious or fatal injury.

Disconnect the negative battery cable.

Remove the spark plug wire from the ignition coil.

Always remove the spark plug wires by grasping the top of the spark plug insulator, turning the boot 1/2 turn and pulling straight up in a steady motion.

Installing

Failure to route the wires properly could cause the radio to reproduce ignition noise, cross ignition of the spark plugs or short circuit the wires to ground. Install the spark plug insulators over the spark plugs. Ensure that the top of the spark plug insulator covers the upper end of the spark plug, then connect the other end to the ignition coil.

Install the negative battery cable.
