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.

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 cables.
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).

Notice: Replacement components must be the correct part number for the application. Components requiring the use of the thread locking compound, lubricants, corrosion inhibitors, or sealants are identified in the service procedure. Some replacement components may come with these coatings already applied. Do not use these coatings on components unless specified. These coatings can affect the final torque, which may affect the operation of the component. Use the correct torque specification when installing components in order to avoid damage.

2. Tighten the nozzle.

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

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.
