The timing chain (not belt) is not a thing that you should have to replace on a mileage basis. Just keep the engine in tune, change the oil per manufacturers recommendations, and drive it. By the way, a timing belt should be changed approximately every 75K to 80K miles. Your engine will have a chain.
