Detailed Description

This Bosch alternator is engineered for charging-system service on GM platforms that use a 6-groove belt drive and a 12-volt electrical system. The remanufactured design supports OE-style replacement needs for Chevrolet C1500, K1500, Tahoe, Astro, Blazer, S10, Express, and GMC C/K truck and van applications, along with Cadillac Escalade and Isuzu Hombre coverage in the listed years. The AL8706X also cross-references Bosch-style replacement numbers used for the same application, including 10463651 and 10463652.

Compatible With 1996-2000 Chevrolet C2500, 1996-2000 Chevrolet C3500, 1996-2000 GMC C2500, 1996-2000 GMC K3500, 1999-2000 Cadillac Escalade, and other listed GM fitments where the vehicle calls for a 100-amp or 105-amp alternator configuration. Use the fitment notes to confirm whether your vehicle is equipped for a single alternator or dual alternators, and whether the application calls for the 100-amp or 105-amp version.

What It Helps Solve

• Low battery charge or repeated battery drain
• Dim lights or unstable electrical output
• Charging-system warning lights
• Alternator noise or bearing-related charging issues
• Failure of the original alternator on GM truck, van, or SUV applications

Installation Notes and Tips

• Verify amperage, pulley groove count, plug type, and rotation before installation.
• Confirm the vehicle’s alternator setup matches the fitment notes, especially 100-amp versus 105-amp applications.
• Check belt condition and charging-system wiring during replacement.
• Inspect battery state of charge and test the charging system after installation.
• Fits 1996-1999 Chevrolet C1500, 1996-1999 GMC K1500, and 1999-2000 Chevrolet Express 3500, with the listed alternator configurations.
