Reman Alternator Line Details

Denso Reman Alternators are processed through testing and inspection steps that include high-voltage validation of stators, rectifiers, and rotors, along with bearing checks to OE standards. Slip rings are finished to a fine surface specification to reduce brush wear, and premium lubricants are used in the bearing system. The result is a remanufactured charging unit built to meet the electrical and thermal demands of late-model vehicles.

This part cross-references Remy 22058 and 22060 for the same application.

What This Alternator Helps Address

• Battery warning light caused by weak charging output
• Low system voltage during idle or accessory use
• Charging instability in start/stop vehicle systems
• Noise or wear related to alternator bearing condition
• Poor fitment from non-OE-style replacement units
