Spark Plug: Service and Repair
REMOVAL
Fig.35 Heat Shields
On these engines, spark plug cable heat shields are pressed into the cylinder head to surround each cable boot and spark plug.
If removal of the heat shield(s) is necessary, remove the spark plug cable and compress the sides of shield for removal. Each shield is slotted to allow
for compression and removal. To install the shields, align shield to machined opening in cylinder head and tap into place with a block of wood.
1. In these engines: Prior to removing spark plug, spray compressed air around spark plug hole and area around spark plug. This will help prevent
foreign material from entering combustion chamber.
2. Remove spark plug from cylinder head using a quality socket with a rubber or foam insert.
Fig.37 Cable Removal
3. In these engines: Always remove spark plug or ignition coil cables by grasping at the cable boot. Turn the cable boot 1/2 turn and pull straight
back in a steady motion. Never pull directly on the cable. Internal damage to cable will result.
4. Inspect spark plug condition. Refer to Spark Plug Conditions.
CLEANING
The plugs may be cleaned using commercially available spark plug cleaning equipment. After cleaning, file center electrode flat with a small point file
or jewelers file before adjusting gap.
