Detailed Description

This Remy alternator is built for Lexus vehicles that use a Nippondenso-style charging system and require a 150 amp, 12-volt remanufactured replacement. It is listed for 2006-2013 Lexus IS250, 2006-2013 Lexus IS350, 2007-2011 Lexus GS350, and 2006 Lexus GS300 applications. Part Number 12724 is also cross-referenced with 27060-31060 for the same application.

Because the unit includes an internal regulator and pulley, it is suited to direct alternator replacement work where the original charging component has failed, output has dropped, or voltage control has become inconsistent. Use the vehicle’s original alternator specifications to confirm the correct match before installation.

What This Alternator Helps Resolve

• Battery warning light caused by alternator output loss
• Low charging voltage at idle or under load
• Dim lights or unstable electrical performance
• Battery drain after the vehicle is running
• Charging system noise or alternator failure on Lexus IS250, IS350, GS350, and GS300 models

Installation Notes and Tips

Verify the OE alternator style, amperage rating, rotation direction, and pulley configuration before installation. Confirm belt alignment, electrical connector fitment, and charging voltage after the alternator is installed. On Lexus IS250 and Lexus IS350 applications, matching the original Nippondenso-based configuration is important for proper operation.

Quality Assurance

Remy Premium Remanufactured components are remanufactured to support OE-style replacement needs for import charging systems. This alternator is built around the listed electrical and mechanical specifications for the confirmed Lexus applications.
