Removal Procedure

NOTE: Use care in removing the fuel injectors in order to prevent damage to the fuel injector electrical connector pins or the fuel injector nozzles. Do not immerse the fuel injector in any type of cleaner. The fuel injector is an electrical component and may be damaged by this cleaning method.
IMPORTANT: The Denso fuel injectors that are installed in the 5.3L (L59) E85 application will not have O-rings and retaining clips serviced separately. Therefore, the fuel injectors will be replaced whenever an O-ring or clips needs to be replaced.
IMPORTANT: The engine oil may be contaminated with fuel if the fuel injectors are leaking.
