PLUG INSTALLATION
Special care should be taken when installing spark plugs into the cylinder head spark plug wells. Be sure the plugs do not drop into the plug wells
as electrodes can be damaged.
Always tighten spark plugs to the specified torque. Over tightening can cause distortion resulting in a change in the spark plug gap or a cracked
porcelain insulator.
When replacing the spark plug and ignition coil 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. It could cause cross ignition of the spark plugs or short circuit the cables to
ground.
1. Start the spark plug into the cylinder head by hand to avoid cross threading.
2. Tighten spark plugs to 35-41 N.m (26-30 ft. lbs.) torque.
3. Install spark plug cables over spark plugs.
