Denso 210-5381 Alternator

Denso 210-5381 Reman Alternator Overview

The Denso 210-5381 reman alternator is a 12-volt, 160-amp charging component built for vehicles with demanding electrical loads. It is engineered for direct-fit service on select Cadillac, Chevrolet, GMC, and Hummer applications, including Escalade, Silverado 1500, Tahoe, Sierra 1500, and Yukon models.

Denso reman alternators are processed and tested to OE-level standards, with internal components validated for electrical performance and bearing durability. This reman alternator uses an internal fan, internal regulator, and clockwise rotation for the specified Delco OE family applications.

Key Features

• 12.0-volt alternator with 160-amp output
• Internal fan and internal voltage regulator
• Clockwise rotation
• Built for Delco Remy OE family applications
• Remanufactured to support reliable charging performance
• First Time Fit design for proper mounting and alignment
• Compact, lightweight construction for modern electrical systems

Product Details

Denso reman alternators are rebuilt with attention to OE assembly benchmarks and electrical durability. Stators and rectifiers are tested to 300 volts, rotors to 600 volts, and rotor slip rings are finished to a fine surface standard to reduce brush wear. Bearings are validated to OE standards and lubricated with premium OE-grade lubricant. For drivers and technicians, that means a charging system component built to restore stable output in vehicles that rely on multiple electronic systems.

This part cross-references Bosch AL7599X for the same application. The Denso 210-5381 is a direct replacement choice for many 2007-2014 Cadillac Escalade and Escalade ESV models, as well as select Chevrolet Silverado, Suburban, Tahoe, GMC Sierra, Yukon, and Hummer H2 applications.

Common Problems This Alternator Can Address

• Battery warning light caused by low charging output
• Dim headlights or fluctuating electrical performance
• Slow battery recovery after starting
• Charging system noise related to worn internal components
• Voltage instability in vehicles with high accessory demand

Installation Notes and Fitment Tips

Verify the 156 mm (6 1/8 in.) case diameter and Delco unit configuration before installation. Confirm 12-volt system requirements, clockwise rotation, internal regulator setup, and 160-amp specification against the original unit.
