INSTALLATION OF SPARK PLUGS.
Before installing spark plugs, ascertain that the threads within the cylinder are clean and not damaged.
1. Apply anti-seize compound sparingly on the threads and install gasket and spark plugs. Torque 360 to
420 inch-pounds.
—CAUTION—
Make certain the deep socket is properly seated on the spark plug
hexagon as damage to the plug could result if the wrench is
cocked to one side when pressure is applied.
2. Carefully insert the terminal insulator in the spark plug and tighten the coupling unit.
