Detailed Description

MPA Electrical 10255 is a remanufactured alternator engineered around the listed Nippondenso configuration and OE-style mounting requirements. It is specified with a 150 amp rating, internal regulator, internal fan, and a 6-groove serpentine decoupling pulley, making it a strong match for late-model GM trucks and vans that use this charging-system layout. For buyers searching for a remanufactured alternator for a Chevrolet Silverado 1500, Silverado 2500 HD, Silverado 3500 HD, Tahoe, Express 2500, or GMC Sierra, Yukon, or Savana, this part number provides a focused fitment match.

Compatible vehicle coverage includes 2014-2024 Chevrolet and GMC applications, with fitment notes calling out 150 amp alternator requirements on several models and primary-position use on select dual-alternator HD trucks. Part number 10255 should be matched to the existing alternator’s amperage, pulley style, and connector/clock position before installation.

What It Helps Solve

Battery warning light caused by alternator output loss
Low charging voltage at idle or under electrical load
Dim lights, slow accessory operation, or weak battery recovery
Charging-system failure on 150 amp GM truck and van applications
Replacement needs for worn bearings, brushes, or regulator faults

Installation Notes and Tips

Verify the existing alternator’s amperage rating, pulley type, rotation, and clock position before ordering. This unit is listed for N/A and Primary positions depending on application, so confirm whether your vehicle uses a single alternator or dual alternator setup. For 2018-2019 Silverado 2500 HD, Silverado 3500 HD, Sierra 2500 HD, and Sierra 3500 HD, check whether the vehicle uses the primary alternator or a single 150 amp alternator configuration. Compare the original part number and connector layout to the replacement before installation.
