INSPECTION AND MAINTENANCE

Spark Plugs

65D180

You should inspect spark plugs periodically
for carbon deposits. When carbon accu-
mulates on a spark plug, a strong spark
may not be produced. Remove carbon
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 con-
taminants 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.
