• Q: How to replace the fuel injector on 2004 Chevrolet Astro?

  A: Whole fuel system pressure needs relief before starting the Fuel Injector replacement procedure. Initially detach the upper intake manifold assembly and then proceed with removing the fuel meter body assembly . Carefully extract the injector assembly retainer along with the injector retainer lock nuts .

As the injectors function as electrical parts they should not be soaked in any liquid solvent to protect the components from damage since cleaning is unacceptable. The injector functions properly by pulling the tube downward while using a small tip to push down between the terminals until you have effectively removed it. Before Fuel Injector assembly installation oil the o-ring seals of the new assembly using engine oil followed by insertion into the fuel meter body . Use the required injector assembly retainer and install the corresponding lock nuts before tightening them to 3 nm (27 lb in.). Position the fuel meter body assembly.
