Most manufacturers recommend replacing the timing belt every 60,000 to 100,000 miles, but this can vary depending on the make and model of the vehicle. Failure to replace a worn or damaged timing belt can result in catastrophic engine failure. In interference engines, where the valves and pistons occupy the same space, a broken timing belt can cause the pistons to collide with open valves, leading to bend or break components and extensive damage that can be costly to repair.
