• Q: How to replace the alternator on 2004 GMC Envoy?

  A: You must begin by taking off the negative Battery Cable and Drive Belt before proceeding. You must raise the vehicle to a suitable height that allows access to the A/C Compressor through the wheelhouse before removing the left front wheel and left wheelhouse liner. The A/C Compressor electrical connector should be disconnected from its bracket but removal of a/c refrigerant is optional. Thankfully the A/C Compressor's upper bolt needs to stay on the compressor unit through the removal process of its mounting bolts (2, 3). The next step requires lowering the vehicle while moving the protective boot that covers the generator output bat terminal to gain access. Begin by unscrewing the generator output bat terminal nut to disconnect the generator lead from the generator before removing the generator wiring harness connector . Before removing the generator secure clearance by removing three mounting bolts and the engine lift bracket. Place the A/C Compressor in front positioning to access the generator better before removing the generator from the engine compartment. Placement of the generator should be on the engine and installation of the engine lift bracket follows next. Place generator mounting bolts and ensure sequential torque at 50 n.m (37 lb ft). Install the generator output bat terminal nut by tightening it to 20 n.m (15 lb ft) torque specification. Thread the protective boot over the generator output bat terminal before connecting the wiring harness connector to the generator. Lift the vehicle once again to reach the A/C Compressor and set the compressor in place on the engine before screwing in the mounting bolts (2, 3) at 50 n.m (37 lb ft). Install the wheelhouse liner and front wheel on the left side before securing the compressor electrical connector to its bracket. Follow this procedure for Drive Belt installation while you lower the vehicle and reconnect the Battery Cable's negative terminal.
