Injection Nozzle Replacement EFI/MFI

Tools Required

J 39664 Nozzle Socket

Important: When removing an injection nozzle, use the J 39664 Nozzle Socket. Remove the nozzle using the 30 mm hex portion. Failure to do so will result in damage to the injection nozzle.

1. Remove the negative battery cables. Refer to

   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.

2. Remove the fuel line clip.



3. Remove the fuel return hoses (1) from the nozzle (2).
4. Remove the fuel injection line.
5. Cap the nozzle and the lines.
6. Remove the injection nozzle (2) using J 39664 Nozzle Socket.

Important: When installing an injection nozzle, useJ 39664 Nozzle Socket. Install the nozzle using the 30 mm hex portion. Failure to do so will result in damage to the injection nozzle.

1. Install the injection nozzle using J 39664 Nozzle Socket (apply anti-seize compound to threads of nozzle that contact the cylinder).
2. Tighten the nozzle.

Tighten
Tighten the nozzle to 70 N·m (50 lb. ft.).

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.

3. Tighten the fuel injection line.

Tighten
Tighten the nut to 25 N·m (20 lb. ft.).




4. Install the fuel return hoses (1) on the nozzle (2).
5. Install the fuel line clip.
