vehicle has been driven at higher speeds. Immediately check the spark
plugs for correct color. See page 99.

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.
3. Reverse the procedure for spark plug installation. Torque to specifi-
