- Clean the cylinder head around the fuel injectors on bank 1 of any dirt or buildup.
- NOTE:
The 4 bank 1 fuel injection fuel rail bolts (1) are retained in the bank 1 fuel injection fuel rail and may be difficult to remove.
Remove the 4 bank 1 fuel injection fuel rail bolts (1).
- NOTE:
- In some cases, the fuel injectors may be difficult to remove because of heavy carbon build-up or other factors. If the fuel injectors are difficult to remove, apply solvent to the base of the fuel injector bores, and allow adequate soaking time, to loosen the fuel injectors.
- The bank 1 fuel injection fuel rail and fuel injectors are removed as an assembly.
- To prevent material from entering the combustions chambers make sure the area around each fuel injector is clean and free of debris before the fuel injectors are removed from the fuel injector bores.
