4. Inspect the spark plug. Replace it
if the electrodes are worn or if the
insulator is cracked, chipped, or
fouled.
5. Measure the plug gap with a
wire-type feeler gauge. Correct as
necessary by carefully bending the
side electrode.
The gap should be:
0.028—0.031 in (0.7—0.8 mm)
6. Make sure that the spark plug
sealing washer is in good condition,
and thread the spark plug in by hand
to prevent cross-threading.
7. After the spark plug is seated, tighten with a spark plug wrench to
compress the washer.
If installing a new spark plug, tighten 1/2 turn after the spark plug
seats to compress the washer. If reinstalling a used spark plug,
tighten 1/8 to 1/4 turn after the spark plug seats.
TORQUE: 18 N∙m (1.8 kgf∙m, 13 lbf∙ft)
The spark plug must be securely tightened. An improperly tightened
spark plug can become very hot and may damage the engine.
