Spark Plug: Testing and Inspection
Procedure
1. Disconnect the spark plug cable from the spark plug.
NOTE: Pull on the spark plug cable boot when removing the spark plug cable, not the cable, as it may be damaged.
2. Using a spark plug wrench, remove all of the spark plugs from the cylinder head.
CAUTION: Take care not to allow contaminants to enter through the spark plug holes.
3. Check the spark plugs for the following:
-
Broken insulator
-
Worn electrode
-
Carbon deposits
-
Damaged or broken gasket
-
Condition of the porcelain insulator at the tip of the spark plug
4. Check the spark plug gap using a wire gap gauge, and adjust if necessary.
Standard value: 1.0 to 1.1 mm (0.039 to 0.043 in)
5. Re-insert the spark plug and tighten to the specified torque. If it is overtorqued, damage to the threaded portion of cylinder head might result.
