2005 Chevrolet Express 2500 Fuel Injector Parts Questions & Experts Answers

• Q: How to replace the fuel injector on 2005 Chevrolet Express 2500?

  A: The first step in Fuel Injector replacement consists of fuel meter body assembly removal. The next step involves removing both the injector assembly retainer together with the lock nuts. Push the poppet nozzle tube downward while using small tip punches between injector terminals to remove the injector without harming its electrical terminals. The complete injector assembly operates as one unit thus remaining out of any liquid cleaning solutions since immersion may lead to damage while no cleaning techniques are advisable. New injectors need proper matching with their corresponding applications because each injector has flow-rate-specific calibration measurement. Start by applying clean engine oil to fresh o-ring seals for the new injector then place the seals onto the injector unit. Place the Fuel Injector assembly into the socket and fasten it with retainer assembly and retainers-to-lock nut connections while tightening nuts up to 3.0 n.m (27 lbf in). Install the fuel meter body assembly when the task is complete.
