Denso 210-1017 Alternator

Denso Reman Alternator for Cadillac XTS

The Denso 210-1017 reman alternator is a 12-volt charging system component built for select Cadillac XTS applications. It uses an internal fan, internal regulator, and clockwise rotation to match OE-style electrical and mounting requirements.

For 2013-2019 Cadillac XTS models, this remanufactured alternator is built to support vehicles with high electrical demand and sensitive onboard electronics. The Denso 210-1017 is a direct-fit charging solution for drivers and technicians looking for OE-style performance in a reman unit.

Key Features

• 12.0-volt alternator with 220 amp output
• Internal fan and internal voltage regulator
• Clockwise rotation
• Remanufactured to Denso OE standards
• First Time Fit design for proper mounting and alignment
• Built for Cadillac XTS charging system applications

Product Details

Denso reman alternators go through testing and inspection steps that focus on electrical reliability and OE-style fit. Stators and rectifiers are tested under high voltage, rotors are checked at even higher voltage, and slip rings are finished to a fine surface to reduce brush wear. Bearings are validated to OE standards and lubricated with premium OE-grade grease. The result is a reman alternator engineered for consistent charging performance in modern vehicles such as the Cadillac XTS.

This part cross-references BBB Industries 11645 for the same application.

Common Charging System Issues

• Battery warning light or charging system warning
• Low battery voltage after driving
• Dim lights or unstable electrical operation
• Alternator noise from worn bearings or internal wear
• Charging failure on Cadillac XTS 220 amp applications

Installation Notes

Verify the vehicle’s original alternator specifications before installation, including amperage, rotation direction, and regulator type.
