Spark Plug: Service and Repair
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.
Never Wire Brush Spark Plugs. The spark plug insulator tip is harder than the bristles of wire brushes. Bristles of wire brushes can leave a conductive,
metallic film on the insulator which could lead to conductive deposits. Conductive deposits can cause spark plug failure and engine misfire. Use a
jewelers file to remove deposits from the electrode gap or use a spark plug cleaning machine to clean spark plugs.
Setting Spark Plug Electrode Gap
Use the proper gapping tool when setting the electrode gap.
REMOVAL
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
1. To avoid cross threading, start the spark plug into the cylinder head by hand.
2. Tighten spark plugs to 28 Nm (20 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.
