When do you change the timing belt on a 2002 BMW?

The timing belt on a 2002 BMW should typically be replaced every 60,000 to 100,000 miles, depending on the specific engine model. It's essential to check the owner’s manual for the manufacturer's recommendations, as some BMW models may use a timing chain instead, which generally requires less frequent replacement. Additionally, if you notice any signs of wear, such as cracks or fraying, it's wise to change it sooner. Regular maintenance can help prevent serious engine damage.
