Spark Plug: Service and Repair

REMOVAL
When replacing the spark plugs and spark plug cables, route the cables correctly and secure them in the appropriate retainers. Failure to route the cables properly can cause the radio to reproduce ignition noise, cross ignition of the spark plugs or short circuit the cables to ground.

Always remove cables by grasping at the boot, rotating the boot 1/2 turn, and pulling straight back in a steady motion.

1. Prior to removing the spark plug, spray compressed air around the spark plug hole and the area around the spark plug.
2. Remove the spark plug using a quality socket with a foam insert.
3. Inspect the spark plug condition.

INSTALLATION
When replacing the spark plugs and spark plug cables, route the cables correctly and secure them in the appropriate retainers. Failure to route the cables properly can cause the radio to reproduce ignition noise, cross ignition of the spark plugs or short circuit the cables to ground.

1. To avoid cross threading, start the spark plug into the cylinder head by hand.
2. Tighten spark plugs to 17.5 Nm (13 ft. lbs.) torque.
3. Install spark plug cables over spark plugs. A click will be heard and felt when the cable properly attaches to the spark plug.
