How to replace the Fuel Injection Fuel Rail Assembly for Bank 1 (LLT) (3.6L) on Chevrolet Traverse?

Question

Accepted Answer

The first step to replace the fuel injection Fuel Rail assembly for bank 1 (LLT) (3.6L) requires using ch-48027 or without it to relieve fuel system pressure before beginning the work. The first step includes removal of the fuel pipe shield followed by removing the Intake Manifold. First you should detach the high pressure fuel pipe then throw it away alongside the Fuel Rail crossover pipe. Start by extracting the foam insulation from between the fuel rails before unconnecting the Fuel Pressure Sensor wiring link and severing the harness tie straps. The procedure to remove the Fuel Rail requires taking off its mounting bolts together with the Fuel Pressure Sensor while discarding all direct Fuel Injector hold down clamps since these injectors need rebuilding when separated from their Fuel Rail position or cylinder head placement. Rebuilding fuel injectors should be performed after removing the Fuel Rail. Rebuilt direct fuel injectors must enter the cylinder heads while new direct injector hold down clamps need installation. A new Fuel Rail requires lubrication of its injector cups with gm p/n 12345610 (Canadian P/N 9931930) silicon-free engine oil or equivalent before proper placement. Begin installation by securing the outer Fuel Rail bolts followed by the inner bolts while finishing the installation by hand tightening them. The bank 1 Fuel Rail bolts should receive initial torque of 12 nm (106 lb in) and final torque should be 23 nm (17 lb ft). The installation process starts with introducing a new high pressure fuel pipe along with a new Fuel Rail crossover pipe. Mount and connect the high pressure fuel sensor while joining the Fuel Injector wiring harness electrical connector to the fuel injectors and Fuel Rail and Fuel Pressure Sensor. Check for fuel leaks during an ignition turn-on and turn-off procedure. The last step involves both reinstallation of the foam insulator along with the Intake Manifold along with the fuel pipe shield along with the low side fuel pressure service port cap and the fuel tank cap.
