SPARK PLUG
DESCRIPTION - PLATINUM PLUGS
The V6 engine uses platinum resistor spark plugs. They have resistance values of 6,000 to 20,000 ohms when checked with at least a 1000 volt tester.
Do not use an ohm meter to check the resistance of the spark plugs. This will give an inaccurate reading.
CAUTION: Cleaning of the platinum plug may damage the platinum tip.
Apply anti-seize compound to spark plug threads only at point (1).
When the spark plug has a single or double platinum tip (2), a thin platinum pad may be welded to both, or just the center electrode end(s).
1. Extreme care (1) must be used to prevent spark plug cross-threading, mis-gapping and ceramic insulator damage during plug removal and installation.
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. 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.
