Spark Plug Wire Replacement

Removal Procedure


    Object Number: 317450  Size: SH

  1. Remove the spark plug wire from the spark plug.
    1. Twist the boot 1/2 turn before removing the boot.
    2. Pull only on the boot or use a tool designed for this purpose in order to remove the wire from the spark plug.
  2. Remove the spark plug wire from the distributor.
    1. Twist each spark plug boot 1/2 turn.
    2. Pull only on the boot or use a tool designed for this purpose in order to remove the wire from the distributor.
  3. Remove the spark plug wire from the wire separators.

Installation Procedure

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.


    Object Number: 317450  Size: SH
    Install the spark plug wire at the distributor.
  1. Install the spark plug wire to each spark plug.
  2. Install the wire to the wire separators.

    Important: Wire routing must be kept intact during service and followed exactly when wires have been disconnected or replaced.

  3. Inspect the wires for proper installation:
    1. Push sideways on each boot in order to inspect the seating.
    2. Reinstall any loose boot.
    3. Any time the spark plug wire or boot are installed on the spark plug, new dielectric grease needs to be applied inside the boot.
