How Much Does an Alternator Replacement Cost?

Alternator Replacement Service and Cost

Best Practices

The entire starting and charging system should be inspected before replacing the alternator to eliminate other problems that may be affecting the alternator's performance. For instance, a weak battery and/or battery cables will result in a failed alternator test.

The alternator belt may be partially or totally removed while replacing the alternator, so if it shows signs of wear, this is a good time to replace it.

Common Symptoms

A weak alternator can result in dimming of the dashboard lights and the headlights.

A failing alternator can cause problems starting the vehicle and may result in a repeated need to jump start the vehicle.

Common Misdiagnoses

If your battery cannot deliver 10 volts or more during a battery load test, the BMW 640i xDrive may continue to experience starting problems if the battery is not replaced.
