SPARK PLUG INSPECTION
Spark plug condition is indicative of engine operation. The spark plug firing end
condition should be read after the engine has been warmed up and the vehicle
has been driven at higher speeds. Immediately check the spark plug for correct
color.
WARNING
A hot exhaust system and engine can cause burns. Wear protective gloves
when removing a spark plug for inspection.
1. Remove the left side panel and hood.
2. Remove the spark plug cap.
3. Using the spark plug wrench provided in the tool kit, rotate the spark plug
counter-clockwise to remove it.
4. Reverse the procedure for spark plug installation. Torque to specification.
5. Reinstall the spark plug cap. Verify an “audible” click is heard when installing
the plug cap.
