• Q: How to replace the fuel rail assembly on 2004 Chevrolet Aveo?

  A: A proper replacement of the Fuel Rail assembly begins with reducing fuel pressure while also disconnecting the negative Battery Cable. Start by removing the bracket bolts along with the bracket from the intake manifold before separating the Fuel Injector connectors and fuel feed line. You should remove the Fuel Rail mounting bolts while protecting the Fuel Injector electrical connectors and tips and o-rings from damage. Also plug the Fuel Rail ports to prevent contamination before excluding compressed air cleaning methods. When an injector breaks free from the rail it should be followed by replacing the injector o-ring seals and retaining clip before any other repairs. To extract the Fuel Injector you must separate the Fuel Rail along with attached fuel injectors then remove each retainer clip before pulling both Fuel Injector pieces downwards and out of the assembly while discarding the original o-rings. Before installation apply engine oil to new injector o-rings followed by installation onto the injectors before inserting them into the Fuel Rail sockets with terminals positioned outward. First secure the injectors to their retaining clips so these clips face parallel to the harness connectors before you insert the Fuel Rail into its cylinder head position. Secure the Fuel Rail mounting bolts at 25 n.m torque then link the fuel feed hose to the harness connectors by rotating each injector to prevent wiring harness strain. To complete the procedure you must install the intake manifold bracket with bolts then reattach the negative Battery Cable while conducting a leak test for Fuel Rail and injectors.
