Denso 210-1120 Alternator

Denso Reman Alternator 210-1120

This Denso reman alternator is built for 12-volt charging systems and delivers 140 amps with an internal fan, clockwise rotation, and an external regulator type. It is a direct-fit charging solution for select Jeep Liberty applications, including 2007-2008 Jeep Liberty and 2009 Jeep Liberty models.

Denso Reman Alternator 210-1120 is part of the DENSO OE family and is remanufactured to support modern vehicles with multiple electronic loads. The unit is engineered around OE assembly benchmarks, with testing and finishing steps focused on electrical reliability, bearing performance, and reduced brush wear. This makes it a practical choice for Jeep Liberty owners who need stable charging performance from a reman alternator that matches the original application.

Fitment Details

Fits 2009 Jeep Liberty, N/A. Fits 2007-2008 Jeep Liberty, N/A.

This part cross-references Jeep (e.g., 56041693AE) for the same application.

Charging System Performance

Denso reman alternators are tested to verify stator and rectifier integrity, while rotor components are evaluated under high-voltage conditions. The slip rings are finished to a fine surface specification to reduce brush wear, and the bearings are validated to OE standards with premium lubricant. For Jeep Liberty charging system service, Denso 210-1120 supports consistent output for vehicles with factory electronics, lighting, and accessory loads.

What It Helps Address

• Battery warning light caused by alternator output loss
• Low charging voltage during driving or idling
• Electrical system instability in a Jeep Liberty
• Noise from worn alternator bearings
• Fitment issues from a mismatched replacement alternator

Installation Notes

Verify the vehicle year, engine configuration, and charging system layout before installation. Confirm pulley alignment, connector style, and mounting points against the removed unit. Because this alternator uses an external regulator type, the vehicle’s charging control setup should be checked during diagnosis and replacement.

Quality Assurance

Denso reman alternators are produced to OE-style standards and undergo electrical and mechanical validation before release. The DENSO OE line is known for precise fitment and dependable charging performance in demanding automotive applications.
