Removal & Installation

  1. Disconnect negative battery cable. Unplug connectors at ignition module. Disconnect spark plug wires from coil pack. Remove ignition module from engine block. Remove coils and assembly plate.
  2. On 2.5L engines, inspect crankshaft sensor "O" ring for wear, cracks or other damage. See Figure. Replace if necessary. Lubricate new "O" ring with engine oil before installing. To install, reverse removal procedures.
NOTE: If spark plug boots adhere to spark plugs, use Boot Remover (J-36011). Twist first and then pull upward. Boots must be in place on housing prior to ignition system assembly installation or damage may result.
