2010 Cadillac STS Fuel Injector Parts Questions & Experts Answers

• Q: How to replace the fuel injectors on 2010 Cadillac STS?

  A: The high side fuel system pressure must be relieved before replacing the fuel injectors. The correct positioning of injectors must be noted to achieve alignment when installation occurs. Secondly you need to separate the fuel injection Fuel Rail assembly from either bank 1 or bank 2 units based on necessity. Remove the three Fuel Injector retaining rings after which detach the combination of direct fuel injectors with their harness by disconnecting the electrical connector. The j 2619-01 with j-37281-a should be used to evenly remove the injectors if required. The technicians should eliminate upper o-ring seals, plastic spacers, retaining rings, isolator cups, and teflon seals before proceeding. The j 39313 and en-47909 should be used to clean Fuel Rail injector bores during inspection. Apply gm p/n 12345610 silicon-free engine oil or its equivalent to a new o-ring then install a new sequence of upper o-ring seal, plastic spacer, retaining ring, isolator cup and teflon seal on the fuel injectors. Little by little insert the en-48266-1 to the injector tip while installing a new teflon seal across its groove inside the injector. Drop the en-48266-1 from the injector tip and put the en 48266-2 on instead while using proper torque to resize the teflon seal through tool rotation. After proper routing of electrical wiring to prevent damage you should install the direct fuel injectors together with the harness as one assembly while connecting the electrical connector. The service requires replacement of the fuel injection Fuel Rail assembly either on bank 1 or bank 2.
