Checking the spark plug

The spark plug is an important engine
component, which is easy to check.
Since heat and deposits will cause any
EAU19253
spark plug to slowly erode, the spark
plug should be removed and checked
in accordance with the periodic main-
tenance and lubrication chart. In addi-
tion, the condition of the spark plug
can reveal the condition of the engine.
To remove the spark plug
1. Place the vehicle on the center-
1
stand.
2. Remove panel A. (See page 6-7.)
3. Remove the spark plug cap.
