Part number 210-1157 is a remanufactured OE-style replacement that supports vehicles with internal regulation, internal fan design, and clockwise rotation.

Key Features

• 12.0-volt alternator with 130 amp amperage rating
• Internal fan type and internal regulator type
• Clockwise rotation direction
• Denso OE family reman alternator construction
• Built for OE-style fitment on Toyota charging systems
• Part number 210-1157 for direct reference

Product Details

Denso reman alternators are rebuilt to OE standards with attention to electrical performance, bearing quality, and fitment accuracy. Internal components are tested during the remanufacturing process, including high-voltage validation of stators, rectifiers, and rotors, while slip rings are finished to reduce brush wear. For Toyota Tundra and Toyota Sequoia owners, this alternator provides a direct replacement option for vehicles that rely on stable charging output for modern electronics and engine management systems. The Denso 210-1157 is also cross-referenced with Toyota 27060-0S010 for the same application.

What It Helps Address

• Low charging voltage or battery warning lights
• Alternator noise caused by worn internal bearings
• Charging instability in Toyota Tundra and Toyota Sequoia electrical systems
• Failure from worn brushes, slip rings, or rectifier components
• Poor OE-style fitment from mismatched replacement units

Installation Notes and Tips

Verify the vehicle year, model, and amperage rating before installation. This alternator uses an internal regulator and clockwise rotation, so matching the original unit is important for proper charging performance. Confirm belt alignment, pulley condition, and electrical connector fitment during replacement on Toyota Tundra and Toyota Sequoia applications.

Quality Assurance

Denso reman alternators are built around OE assembly benchmarks and validated for demanding electrical and heat conditions. Bearings are checked to OE standards and lubricated with premium OE-grade lubricant, supporting reliable operation in daily driving and heavy electrical loads.
