Q: How to replace the alternator on GMC Yukon?
A:
Before generator replacement start by disconnecting the negative cable of the battery. Begin by removing the intake manifold sight shield followed by the accessory Drive Belt. Start by disconnecting the engine harness electrical connector that serves the generator before placing the generator battery jumper cable boot into position. First remove the generator bolts then unfasten the battery jumper cable terminal from the generator stud and battery jumper cable nut before extracting the generator component. Place the generator into position before securing bolts to 55 nm (41 lb ft). The generator battery jumper cable terminal should be reconnected to the generator stud followed by securing the battery jumper cable nut to the generator while maintaining torque setting at 9 nm (80 lb in). Secure the battery jumper cable boot in position while joining the engine harness electrical connector to the generator. Finalize your work by installing the accessory Drive Belt and intake manifold sight shield and reinstate the negative Battery Cable.
