BBB Industries 11021 Alternator

Remanufactured Alternator for GM Minivans

BBB Industries 11021 is a remanufactured 12-volt alternator built for charging-system replacement on select GM minivans. It delivers 105 amps and uses an internal voltage regulator, internal fan, and air cooling for standard serpentine-belt applications.

Compatible with 2005-2007 Buick Terraza, 2005-2007 Pontiac Montana, 2005-2007 Saturn Relay, and 2005-2006 Chevrolet Uplander, this BBB Industries REMAN ALTERNATOR is built around OE Valeo specifications for direct-fit service. The 11021 part number is also a useful reference when matching the correct charging unit for these vehicles.

• 12-volt alternator with internal voltage regulator
• OE manufacturer reference: Valeo
• Serpentine belt drive with 6-groove pulley included

Product Details

BBB Industries 11021 is a remanufactured alternator for vehicles that use a conventional pulley and serpentine belt setup. The unit is configured with a 6-groove pulley, internal fan, and internal regulator, making it a direct replacement choice for charging-system service on the Buick Terraza, Pontiac Montana, Saturn Relay, and Chevrolet Uplander. If you are replacing a failing alternator on a 2005-2007 Buick Terraza or a 2005-2006 Chevrolet Uplander, this part number helps confirm the correct electrical and pulley configuration.

This part cross-references OE-style numbers such as 15201678 and TG10S012 for the same application.

Common Problems This Part Can Address

• Battery warning light caused by low alternator output
• Weak charging performance during normal driving
• Dim lights or electrical instability from charging-system wear
• Noise or pulley-related issues from a worn alternator assembly
• Failure to maintain proper system voltage on GM minivans

Installation Notes

Verify pulley groove count, plug clock position, rotation direction, and amperage rating before installation. This alternator uses a serpentine belt drive and an internal regulator, so the vehicle’s charging connector and belt routing must match the OE-style configuration. Confirm fitment by year, make, and model before ordering BBB Industries 11021.
