Spark Plug: Testing and Inspection

SPARK PLUGS INSPECTION





1. REMOVE HIGH-TENSION CORDS AND IGNITION COILS
2. REMOVE SPARK PLUGS
- Using a 16 mm plug wrench, remove the 4 spark plugs from the cylinder head.





3. CLEAN 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.





4. VISUALLY INSPECT SPARK PLUGS
- Check the spark plug for thread damage and insulator damage.
- If abnormal, replace the spark plug.

Recommended spark plug:
ND: K16TR11
NGK: BKR5EKB-11





5. ADJUST ELECTRODE GAP
- Carefully bend the outer electrode to obtain the correct electrode gap.

Correct electrode gap: 1.1 mm (0.043 in.)

6. REINSTALL SPARK PLUGS

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

7. REINSTALL IGNITION COILS AND HIGH-TENSION CORDS
