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 92.

protective gloves when removing a spark plug for inspection.

1. Rotate the spark plug cap.
2. Using the special wrench provided in the tool pouch, rotate the

spark plug counterclockwise to remove it.

3. Inspect the electrodes for wear

and carbon buildup. Replace

worn or fouled plugs. Verify that

the gap is at specification before

installation.
