Measure the spark plug gap a with a
wire thickness gauge. Replace the spark
plug or adjust the gap to specification if nec-
essary.
Spark plug gap:
0.7–0.8 mm (0.028–0.031 in)
To install a spark plug:
1. Clean the gasket surface.
2. Wipe any dirt from the threads of the
spark plug.
3. Install the spark plug, and then tighten it
to specification.
Spark plug tightening torque:
12.5 N·m (1.25 kgf·m, 9 ft·lb)
4. Install the spark plug cap.
NOTE:
@
G Wipe off any water on the spark plug or
inside the spark plug cap before installing
the cap. Push the spark plug cap down
until it is securely installed.
G If a torque wrench is not available when
you are installing a new spark plug, a good
estimate of the correct torque is 1/4 turn to
1/2 turn past finger tight with the spark
plug wrench included in the tool kit. Have
the spark plug adjusted to the correct
torque with a torque wrench as soon as
possible.
