    Q:
    How to remove and install an alternator on an engine for Chevrolet Astro? Posted by Customer
    A:
    Removal begins with disconnecting the cable from the negative terminal of the battery. On CMFI and CSFI engines, the air cleaner assembly is removed. On carbureted TBI engines (and CMFI engines, if necessary), the upper fan shroud is removed. The electrical connectors are then detached from the alternator. If necessary, the drivebelt is removed from the alternator pulley before the alternator mounting bolts and braces (if used) are removed. Finally, the alternator is removed from the engine. Installation is the reverse of removal. On models equipped with multiple V-belts, the drivebelt adjustment procedure is performed.

    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.

    What steps should be followed for the engine for the 2005 Chevrolet Colorado? Posted by Customer
    A:
    Raise and support the vehicle, remove the left front wheel and fenderwell liner. Unbolt the refrigerant line from the engine lifting bracket (without disconnecting it) and remove the engine lifting bracket. Disconnect the electrical connector at the air conditioning compressor, remove the compressor mounting bolts, and lower the compressor for access to the alternator bolts. Move the electrical harness out of the way if necessary, then remove the alternator mounting bolts and the alternator.
