CAUTION:
Do not use any tools to remove or install
the spark plug cap, otherwise the ignition
coil coupler could be damaged. The spark
plug cap may be difficult to remove be-
cause the rubber seal on the end of the
cap fits tightly. To remove the spark plug
cap, simply twist it back and forth while
pulling it up; to install it, twist it back and
forth while pushing it down.
(3) Remove the spark plug.
Measure the spark plug gap with a wire
thickness gauge. Replace the spark plug
or adjust the gap to specification if neces-
sary.

to the specified torque.
Spark plug tightening torque:
12.5 Nm (9.2 ft-lb) (1.27 kgf-m)

NOTE:
Wipe off any water on the spark plug or in-
G
side the spark plug cap before installing the
cap. Push the spark plug cap down until it is

are installing a spark plug, a good estimate
of the correct torque is 1/4 turn to 1/2 turn
past finger tight using 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.
