Product Line Details

Denso reman alternators are part of the Denso OE family and are remanufactured through a controlled process that includes electrical testing of key components, rotor slip-ring finishing, and bearing validation to OE standards. The result is a charging component engineered for proper mounting, stable operation, and consistent performance in vehicles with demanding electronic loads.

Compatible With 2009-2014 Acura TSX, N/A; 2008-2010 Honda Accord, N/A; 2011-2012 Honda Accord, N/A. This part cross-references Honda (31100-R40-A010) for the same application.

What It Helps Address

• Battery warning lights caused by weak alternator output
• Low charging voltage in Acura TSX and Honda Accord applications
• Electrical instability affecting vehicle electronics
• Noise or wear related to aging alternator bearings
• Fitment issues from non-OE-style replacement units

Installation Notes and Tips

Verify the vehicle year, engine configuration, and alternator mounting before installation. Confirm pulley alignment, belt condition, and connector match-up, and compare the removed unit to part number 210-0644 before final assembly. For 2009-2014 Acura TSX and 2008-2012 Honda Accord applications, matching the original electrical and mounting layout helps ensure a clean replacement.

Quality Assurance

Denso reman alternators are tested to OE-focused standards for electrical performance and durability. The remanufacturing process includes validation of stators, rectifiers, rotors, slip rings, and bearings to support reliable charging system operation in modern vehicles.
