Spark Plug Wiring And Boots
Notice: Twist the spark plug boot one-half turn in order to release the boot.
Pull on the spark plug boot only. Do not pull on the spark plug wire or the
wire could be damaged.
Notice: If the boot to wire movement has occurred, the boot will give a false
visual impression of being fully seated. Ensure that the boots have been properly
assembled by pushing sideways on the installed boots. Failure to properly
seat the terminal onto the spark plug will lead to wire core erosion and result
in an engine misfire or crossfire condition, and possible internal
damage to the engine.
Service Precautions
| • | When removing the boot, do not use pliers or other tools that
could tear the boot. |
| • | Do not force anything between the wire and the boot. |
| • | Do force anything through the silicon jacket of the wiring. |
| • | During installation of the boot, make sure the metal terminal
with the boot is fully seated on the spark plug terminal. |
| • | During installation of the boot, make sure the boot has not moved
on the wire. |
Correctly installed boots will be stiff. You will note only slight looseness.
If the terminal has not been properly seated on the spark plug, only the resistance
of the boot will be felt pushing sideways.
Spark Plug Wire Replacement
Keep spark plug wire routings intact during installation. Follow the
exact wire routings when wires have been disconnected or when replacement
of the wires is necessary. Failure to properly route the spark plug wires
can lead to radio noise and cross-firings of the spark plugs, or shorting
of the leads to ground. For the correct routing of the wires, refer to
Ignition System Description
