Fuel Injector and Fuel Rail Replacement: Notes
WARNING: This page is about a different car, the 2006 Pontiac Montana SV6, 2006 Chevrolet Uplander, and 2006 Buick Terraza. However, it is still accessible from the selected car via links, so may be relevant.
An 8-digit identification number is stamped on the fuel rail. Refer to this number if servicing or part replacement is required.
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 brown), be sure to install the black O-ring in the upper position and the brown O-ring in the lower position on the fuel injector. The O-rings are the same size but are made of different materials.
NOTE:
Cap the fittings and plug the holes when servicing the fuel system in order to prevent dirt and other contaminants from entering the open pipes and passages.
IMPORTANT:
If the fuel injectors are found to be leaking, the engine oil may be contaminated with fuel.
