Spark Plug: Testing and Inspection

ON-VEHICLE INSPECTION

NOTE: "Cold" and "Hot" in these sentences express the temperature of the coils themselves. "Cold" is from -10 °C (14 °F) to 50 °C (122 °F) and "Hot" is from 50 °C (122 °F) to 100 °C (212 °F).

INSPECT SPARK PLUGS




a. Disconnect the 3 high-tension cords.

b. Remove the 3 ignition coils.

c. Using a 16 mm plug wrench, remove the 6 spark plugs.




d. Clean the spark plugs.
If the electrode has traces of wet carbon, allow it to dry and then clean with a spark plug cleaner

Air pressure: Below 588 kPa (6 kgf/sq.cm, 85 psi)

Duration: 20 seconds or less

HINT: If there are traces of oil, remove it with gasoline before using the spark plug cleaner.







e. Visually check the spark plug for thread damage and insulator damage.

If abnormal, replace the spark plug




f. Adjust the electrode gap.
Carefully bend the outer electrode to obtain the correct electrode gap.

Correct electrode gap: 1.1 mm (0.043 in.)

g. Using a 16 mm plug wrench, reinstall the spark plugs.

Torque: 18 N.m (180 kgf.cm, 13 ft.lbf)

h. Reinstall the 3 ignition coils.

i. Reconnect the 3 high-tension cords.
