Locate the Alternator: Depending on your car’s model, the alternator may be at the front or side of the engine bay. Consult your vehicle’s manual for its exact location.

Remove the Serpentine Belt: The serpentine belt connects various components in your car. Use a belt tensioner tool or wrench to release the tension and carefully remove the belt from the alternator pulley.

Install the New Alternator: Position the new alternator in the mounting bracket and secure it with the bolts. Ensure it is firmly in place without any movement.

Reconnect the Wiring: Attach the wiring connectors to the new alternator, making sure they are secure and properly aligned.

Reinstall the Serpentine Belt: Place the belt back onto the alternator pulley and use the belt tensioner to align it properly. Ensure the belt is correctly seated on all pulleys to avoid slippage or damage.

Reconnect the Battery: Attach the negative terminal back to the battery and tighten it.
- Test Your Installation: Start your car and use a multimeter to check the voltage output of the alternator. It should ideally read between 13.5 to 14.5 volts. If the reading is within this range, congratulations, you’ve successfully replaced your car’s alternator.
