    Q:
    How to Remove the Alternator on Chevrolet Avalanche,Silverado,Suburban,Tahoe,GMC Sierra,Yukon,Yukon Denali and Yukon XL? Posted by Customer
    A:
    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.

    Q:
    How is the process different for the 2013 Chevrolet Silverado? Posted by Customer
    A:
    For a V8 model, instead of detaching the clip and bolt for the air conditioning compressor and condenser hose bracket, you simply peel back the weather boot from the B+ terminal and disconnect the battery cable from the alternator. Then, remove the electrical connector and two alternator mounting bolts before removing the alternator.
