levering in the recess in the lower part of the door after
removing the screw.
- Disconnect the spark plug high voltage cable cap;
- Unscrew the spark plug with the spanner provided;
check the spark plug to see if the insulator is cracked,
the electrodes are worn out or excessively sooty.
Also check the condition of the sealing washer and
measure the electrodes gap with a suitable thickness
gauge.
Electrode gap: 0.7 - 0.8 mm
- If necessary adjust the gap by carefully bending the
side electrode. If the spark plug has any of the defects
mentioned above replace it with a plug of the recom-
mended type;
- Insert the plug into the hole with the proper inclina-
tion, screw it in fully by hand and then tighten it with
the specially designed spanner.
Tightening torque: 10 N·m (1 Kg·m)
