120A Alternator with 8-Groove Clutch Pulley for 2010-2023 Lexus GX460, 2008-2022 Sequoia & 2007-2021 Tundra

12V 120A Alternator for Select Lexus GX460, Toyota Sequoia, and Tundra Applications

Internally regulated alternator with 120-amp output, clockwise rotation, and an 8-groove clutch pulley for the exact engine and equipment configurations listed below.

Critical fitment warning: Fitment depends on engine and factory equipment, not model year alone. Sequoia entries require rear DVD and exclude the towing package. Several Tundra entries require rear DVD and the towing package, while later entries use different equipment conditions. The source does not provide GX460 engine details, connector pin count, plug clock position, mounting dimensions, case code, production-date breaks, or formal replacement reference numbers. Confirm the VIN, engine, factory option codes, rear-DVD system, towing package, original alternator label and output, 8-groove clutch pulley, connector, terminal layout, case and mounting points before ordering.

Installation Notes

Charging-system service should be performed by a qualified technician. Before replacement, test the battery, battery cables, grounds, drive belt, tensioner, charge cable, fusible links, and control circuit. Disconnect the battery according to the vehicle service procedure and compare the replacement with the original alternator, including 120A label, case, mounting ears, connector and terminal positions, pulley grooves and clutch function, and rotation.

Follow vehicle-specific torque and belt-routing procedures. After installation, verify belt tracking and tension, battery state of charge, charging voltage and current under load, voltage drop across positive and ground circuits, and the absence of warning lights or diagnostic faults. A weak battery, poor ground, damaged cable, blown fuse, incorrect belt tension, or control-circuit fault can mimic alternator failure.
