How to Remove the Alternator on Chevrolet Avalanche,Silverado,Suburban,Tahoe,GMC Sierra,Yukon,Yukon Denali and Yukon XL?

To remove the alternator on a V6 model, start by disconnecting the cable from the negative battery terminal and removing the air intake duct and accessory drive belt. Unbolt the clamp that secures the heater outlet hose to the alternator mounting bracket, disconnect the electrical connector from the alternator, and peel back the weather boot from the B+ terminal to remove the battery cable from the alternator. Finally, remove the alternator mounting bolts and the alternator. The installation is the reverse of removal. On V8 models, follow similar removal steps as the V6 models. Again, installation is the reverse of removal.
