WARNING:
It is recommended that the engine be cool or
cold when changing the spark plugs. If the
engine is hot, you could burn yourself on the
insulated connector, the spark plug or the
engine itself.

4. When preparing to remove the old spark
plug, guide the socket down over the spark
plug, being careful not to damage the ce-
ramic insulator.

3. To remove the spark plug cable, pull straight
up on the insulated connector, not the cable.
Pulling on the cable may damage the carbon
core conductor.
NOTE:
Spark plugs should be tightened firmly. Over-
tightening can damage the threads in the
aluminum cylinder head. Also, leaving them
too loose can cause the spark plugs to get
very hot and possibly result in damage to the
engine.
7. Replace the cable by pushing the insulated
connector directly down onto the electrode.
Check to be sure it has snapped into place
and can't fall off.
