mended spark plug type and gap for your vehicle. Torque spark plugs to

Spark Plug Inspection
Spark plug condition is indicative of engine operation. Check the spark
plug firing end condition after the engine has been warmed up and the
vehicle has been driven at higher speeds. Immediately check the spark
plug for correct color. See page 107.

protective gloves when removing a spark plug for inspection.

2. Using the special wrench provided in the tool pouch, rotate the
spark plug counterclockwise to remove it.

cation.
