Spark Plugs
65D180
You should inspect spark plugs periodi-
cally for carbon deposits. When carbon
accumulates on a spark plug, a strong
spark may not be produced. Remove car-
bon deposits with a wire or pin and adjust
the spark plug gap.
To access the spark plugs,
1) disconnect the coupler while pushing
the release lever,
2) remove the bolt, and
3) pull the ignition coil out.

EXAMPLE
CAUTION
• When servicing the iridium/plati-
num spark plugs (slender center
electrode type plugs), do not touch
the center electrode, as it is easy to
damage.
• When installing the spark plugs,
screw them in with your fingers to
avoid stripping the threads.
Tighten with a torque wrench to 25
Nm (2.5 kg-m, 18.0 lb-ft). Do not
allow contaminants to enter the
engine through the spark plug
holes when the plugs are removed.
• Never use spark plugs with the
wrong thread size.
CAUTION
When replacing spark plugs, you
should use the brand and type speci-
fied for your vehicle. For the speci-
fied plugs, refer to the
“SPECIFICATIONS” section at the
end of this book. If you wish to use a
brand of spark plug other than the
specified plugs, consult your SUZUKI
dealer.
