SPARK PLUGS
SPARK PLUG RECOMMENDATIONS
Refer to the Specifications section for the recommended spark plug type for your
vehicle. Always torque spark plugs to specification.

SPARK PLUG INSPECTION
Spark plug condition is indicative of engine operation. The spark plug firing end
condition should be read after the engine is warmed up and the vehicle is driven
at higher speeds. Immediately check the spark plug for correct color.
CAUTION
A hot exhaust system and engine can cause burns. Wear protective gloves
when removing a spark plug for inspection.
To inspect the spark plugs, do the following:
1. Lift the cargo box to access the spark plugs.
2. Remove the spark plug cap. Using the spark plug wrench provided in the tool
kit, remove the plug by rotating it counter-clockwise.
3. Reverse the procedure for spark plug installation.
4. Torque to specification.
NORMAL PLUG
The normal insulator tip is gray, tan or light brown. There will be few combustion
deposits. The electrodes are not burned or eroded. This indicates the proper
type and heat range for the engine and the service.
The tip should not be white. A white insulator tip indicates overheating, caused
by use of an improper spark plug or incorrect throttle body adjustments.
