SPARK PLUGS

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.
1. Lift the cargo box. Remove the spark plug cap.
2. 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. Apply anti-seize compound
to the spark plug threads.
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.
Using non-recommended spark plugs can result in serious engine damage.
Always use DW INDUSTRIES-recommended spark plugs or their equivalent.
Always remove all cargo from the cargo box before lifting the box to access
engine components.
A hot exhaust system and engine can cause burns. Wear protective gloves
when removing a spark plug for inspection.
