Fuel Injector: Service Precautions

CAUTION:
^ Color of Service Parts identification clip may differ from color of Production identification clip. Verify identification using part number and parts catalog.
^ Do not interchange fuel injectors. Improper injector installation can cause severe engine damage.
^ Remove all oil and fuel from the cylinders before installing the fuel injectors. Failure to do so can cause hydrostatic lock, resulting in severe engine damage.
^ Do not strike the top of the fuel injector to seat the injector in the cylinder head fuel injector bore. Damage to the fuel injector will occur. Use hand pressure on the top of the fuel injector until the fuel injector hold-down plate is flush with the cylinder head.
