Fuel Injector Replacement
Fuel Injector Replacement
Removal Procedure
Important: If the fuel injectors are leaking, the engine oil may be contaminated with fuel.
1. Remove the fuel rail.
2. Remove the fuel injector by pushing the locking tab on the fuel rail toward the center of the fuel rail.
3. Remove the fuel injector upper O-ring.
4. Remove the fuel injector lower O-ring.
5. Discard the injector O-ring seals.
Installation Procedure
Caution: In order to reduce the risk of fire and personal injury that may result from a fuel leak, always install the fuel injector O-rings in the proper position. If the upper and lower O-rings are different colors (black and blue), be sure to install the blue O-ring in the upper position and the black O-ring in the lower position on the fuel injector. The O-rings are the same size but are made of different materials.
Important:
* Be sure to use the correct part number when ordering replacement fuel injectors.
* The fuel injector O-rings should always be replaced whenever the fuel injectors are serviced. Be sure to install the correct O-ring for the fuel injector. If the O-ring is not seated properly, a vacuum leak is possible and driveability complaints may occur.
1. Lubricate the new upper and lower O-rings with clean engine oil.
2. Install the new upper and lower injector O-rings on the fuel injector.
3. Install the fuel injector on to the fuel rail.
4. Install the fuel rail.
