An incorrect spark plug can
cause engine damage.
For good performance, the spark
plug must be properly gapped
and free of deposits.
1. Disconnect the spark plug cap,
and remove any dirt from
around the spark plug area.
2. Remove the spark plug with a
21 mm (13/16 in) spark plug
wrench.
3. Inspect the spark plug.
Replace it if the electrodes are
worn, or if the insulator is
cracked or chipped. Clean the
spark plug with a wire brush if
you are going to reuse it.
