Spark Plug: Service and Repair
Installation
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. Coat threads of spark plug with anti-seize. Be sure not to get anti-seize ANYWHERE BUT ON THE THREADS OF THE SPARK PLUG..
2. To avoid cross threading, start the spark plug into the cylinder head by hand.
3. Tighten spark plugs by referring to the Torque Specifications chart.
4. Install spark plug cables over spark plugs. A click will be heard and felt when the cable properly attaches to the spark plug.
