Alternator for 2014-2019 Toyota Corolla 1.8L, VIN U & MPI Applications

Alternator for 2014–2019 Toyota Corolla 1.8L

Replacement alternator for the specific Toyota Corolla 1.8L four-cylinder applications listed below.

Critical fitment warning: Fitment changes by model year. The 2017–2018 application requires engine VIN code U, and the 2019 application requires the MPI fuel system. The source does not provide rated amperage, voltage, rotation, pulley type, pulley diameter, groove count, production country, trim, transmission, connector version, or production-date restrictions. Confirm the VIN, engine code, fuel-system type, original alternator label and reference number, rated output, mounting ears, electrical plug, battery-terminal position, and pulley configuration before ordering.

Vehicle Compatibility

• 2014–2016 Toyota Corolla — 1.8L L4
• 2017–2018 Toyota Corolla — 1.8L L4, engine VIN U only
• 2019 Toyota Corolla — 1.8L L4, MPI fuel system only

VIN check: For 2017–2018 vehicles, confirm the engine VIN character is U. For 2019, verify the vehicle uses the MPI fuel system; other fuel-system configurations are not confirmed.

Reference Numbers

11776, 104211-3300, 27060-0T240, 104211-3303, 104211-3301

Reference numbers are provided for comparison. Confirm the number together with the VIN, engine code, fuel system, rated output, connector, mounting points, output terminal, and pulley configuration.

Specifications Requiring Verification

The source does not state amperage, voltage, rotation direction, regulator/fan configuration, or pulley specifications. Match these details directly to the original alternator before purchase.

Package Contents

One alternator. Whether a pulley is installed is not confirmed by the source. Drive belt, tensioner, mounting bolts, wiring, battery-terminal hardware, and installation tools are not confirmed unless shown in the product images.

Diagnostic and Installation Notes

Charging-system work should be completed by a qualified technician. Test the battery, cables, grounds, belt, tensioner, and charging circuit before replacing the alternator. Disconnect the battery according to the Toyota service procedure before removal. Compare the mounting points, connector, output terminal, rated output, and pulley alignment with the original unit. Follow Toyota torque specifications and confirm belt routing and tension. After installation, verify charging voltage and current under load, check for warning lights or abnormal noise, and ensure the battery is fully charged; an undercharged or failing battery can overload a replacement alternator.
