Detailed Description

This BBB Industries REMAN ALTERNATOR, part number 42025, is a remanufactured charging component for 2014-2019 Toyota Corolla and 2017-2018 Toyota Corolla iM models equipped with the Valeo unit and 2-pin alternator plug. It is built with a decoupler pulley, internal regulator, and air-cooled internal fan to match the electrical and belt-drive requirements of the original application. This part cross-references 27060-0T230 for the same application.

BBB Industries remanufactured alternators are rebuilt for direct replacement use in OE-matched charging systems, making this unit a practical choice when servicing a Toyota Corolla alternator or Toyota Corolla iM alternator with the specified Valeo configuration. The 115-amp output supports the vehicle’s electrical demands while maintaining the correct pulley and rotation specifications.

What It Helps Address

• Battery warning light caused by alternator output loss
• Low charging voltage at the battery
• Dim lights or electrical instability during driving
• Noise or belt issues related to a worn decoupler pulley
• Charging system failure on the specified Toyota Corolla and Corolla iM applications

Installation Notes and Tips

Verify the vehicle uses the Valeo unit with a 2-pin alternator plug before installation. Confirm the 6-groove serpentine belt setup, clockwise rotation, and plug clock position 7 to ensure proper fitment. Inspect the belt, tensioner, and charging circuit connections during replacement so the new alternator can operate correctly in the vehicle’s charging system.

Quality Assurance

BBB Industries remanufactured electrical components are processed to meet application-specific replacement requirements for OE-style fitment and function. This part is intended for direct replacement on the listed Toyota Corolla and Toyota Corolla iM vehicles.
