- 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.Posted by GMPartsGiant Specialist
- Q: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.Posted by GMPartsGiant Specialist

- 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 drivebelt. Then, detach the clip for the engine wiring harness from the air conditioning compressor and condenser hose bracket and remove the bolt from the bracket that secures the air conditioning compressor and condenser hose. 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 push aside the heater outlet hose and air conditioning compressor and condenser hoses to remove the alternator. The installation process is simply the reverse of removal. For a V8 model, the process is similar, but 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. The installation process is again the reverse of removal, with a reminder to tighten the alternator mounting bolts securely.Posted by GMPartsGiant Specialist
