Spark Plug Wires


Removal & Installation

At this time the manufacturer does not provide removal and installation procedures for this component. The following procedure is a guideline and may differ from the vehicle you are servicing.

  1. Before servicing the vehicle, refer to the Precautions Section.
    Disconnecting the negative battery cable on some vehicles may interfere with the functions of the on-board computer systems and may require the computer to undergo a relearning process, once the negative battery cable is reconnected.

    If working near and/or around the SRS system and components, be sure to properly disable the SRS system. See disarming/arming the SRS system.

  3. Disconnect the negative battery cable.
  5. Remove the necessary components to gain access to the spark plugs.
  7. Disconnect the spark plug wires from the spark plugs. Be sure to mark the wires for reinstallation.
  9. Disconnect the spark plug wire from the distributor cap. Be sure to mark the wires for reinstallation.
  11. Remove the spark plug wire from its mounting.

To install:

Be sure to use new fasteners, as required.

Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread sealer are identified. Do not use paints, lubricants or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners.

  1. Installation is the reverse of the removal procedure.
    When replacing spark plug wires be sure to route them properly through the retainers. Failure to install them correctly can lead to radio ignition noise, cross firing or shorting.
