130A Alternator for 2009-2014 Acura TSX & 2008-2012 Honda Accord 2.4L

12V 130A Alternator for Acura TSX and Honda Accord

Replacement alternator with clockwise rotation and a 6-groove pulley for the specific Acura TSX and Honda Accord applications listed below.

Critical fitment warning: The Honda Accord application is specifically limited to the 2.4L L4 engine. The source does not state an engine restriction for the Acura TSX; do not assume the Accord engine specification automatically applies to every TSX. The source also does not specify transmission, trim, body style, production date, charging-system option, regulator or fan configuration, connector pinout, mounting dimensions, pulley diameter, or clutch/freewheel design. Confirm the VIN, engine, original alternator label, 130A output, reference number, mounting ears, electrical connector, output-terminal position, and pulley configuration before ordering.

Vehicle Compatibility

• 2009–2014 Acura TSX — engine and configuration restrictions not provided by the source
• 2008–2012 Honda Accord — 2.4L L4 only

Accord V6 applications are not confirmed. TSX engine, body-style, transmission, and trim coverage require VIN and original-part verification.

Confirmed Specifications

• Voltage: 12V
• Rated output: 130A
• Rotation: Clockwise (CW)
• Pulley: 6 grooves

Pulley diameter and solid versus clutch/freewheel pulley design are not confirmed.

Package Contents

One alternator with a 6-groove pulley as specified. Drive belt, tensioner, mounting bolts, electrical wiring, battery-terminal hardware, and installation tools are not confirmed unless shown in the product images.

Diagnostic and Installation Notes

Charging-system diagnosis and alternator replacement should be completed by a qualified technician. Test the battery, cables, grounds, drive belt, tensioner, and charging circuit before replacement. Disconnect the battery according to the Acura or Honda service procedure. Compare the mounting ears, connector, output terminal, pulley alignment, and 130A rating with the original unit. Follow vehicle-specific torque specifications and belt routing. After installation, fully charge the battery, verify charging voltage and current under load, and check for warning lights, belt tracking, or abnormal noise. A weak or undercharged battery can overload a replacement alternator.
