Tools Required

J 36011 Spark Plug Connector Assembly Removal Tool

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

1. Remove the negative battery cable.
2. Turn the ignition key to OFF.
3. Remove the integrated Direct Ignition (IDI) assembly 4 bolts and connector.

5. Use the J 36011 to remove connector assembly(s) is stuck to the spark plugs. Use the tools by first twisting then pulling up on the connector assembly.
6. Remove the debris from the area around the spark plugs.
7. Remove the spark plugs using a spark plug socket.

Specification
Spark Plug Gap: 1.27mm (.050in.)

1. Adjust the spark plug gap using a round wire type spark plug gap gauge. While gapping the plug be sure to keep the platinum pads aligned to ensure maximum plug life.




Notice: 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 locking compound or sealant are identified in the service procedure. 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 in order to avoid damage to parts and systems.

2. Hand start the spark plugs into the cylinder head and tighten.

Tighten
Tighten the plugs to 19 N·m (14 lb ft).

3. Reinstall onto the IDI any spark plug boot connector assembly that stuck to a spark plug.

•	Check to be sure the spring terminal is inside the boot.

•	Reapply dielectric lubricant to the insulator boot.
