PERIODIC MAINTENANCE 2-7
ELECTRODE’S CONDITION
• Check the condition of the electrode.
• If it is extremely worn or burnt, replace the spark plug.
Replace the spark plug if it has a broken insulator, damaged
thread, etc.
INSTALLATION
• Screw the spark plugs into the cylinder head with fingers, and
then tighten them to the specified torque.
Spark plug: 11 N·m (1.1 kgf-m, 8.0 Ibf-ft)
09930-10121: Spark plug wrench set
• Connect the spark plug caps.
Confirm the thread size and reach when replacing the
plug. If the reach is too short, carbon will be deposited
on the screw portion of the plug hole and engine dam-
age may result.
Do not cross thread or over tighten the spark plug, or
such an operation will damage the aluminum threads
of the cylinder head.
