Taking care when replacing a Fuel Injector will protect its electrical connector pins and nozzles from damage. Refrain from submerging fuel injectors in cleaning agents since this could cause harm. Fuel injectors from the 5.3l (L59) e85 application by denso lack o-ring and retaining clip independence for service therefore requiring a complete replacement of the Fuel Injector when either component suffers failure. Be mindful that leaking fuel injectors lead to contamination of the engine oil. Start by removing the
Fuel Rail followed by removing both Fuel Injector retainer clip and the Fuel Injector . The machine should discard both the Fuel Injector retainer clip and the Fuel Injector O-Ring seals (2, 4). Check that your selected new fuel injectors match the requirements of the vehicle application you need them for. Each new Fuel Injector receives two markings from the manufacturer showing its unique part number and its production month , day and year along with production shift . Clean engine oil should be used to lubricate new Fuel Injector O-Ring seals (2, 4) before installing them onto the Fuel Injector. Insert the Fuel Injector into the Fuel Rail injector socket so that the electrical connector faces outward while inserting the retainer clip onto a flange on the Fuel Rail injector socket. Finally, reinstall the Fuel Rail.
