When Should I Replace My BMW X7 Alternator and Serpentine Belt?

For the BMW X7, it is generally recommended to replace the alternator every 80,000 to 120,000 miles, while the serpentine belt should be inspected every 60,000 miles and replaced every 90,000 miles or if any signs of wear are present.

How Do I Tell If My BMW M3 Alternator Is Bad?
