After how many miles do I change the timing belt on my 2001 DTI 1.7 diesel Astra van? Thanking you in advance

It's not only mileage that matters, it's also time as well. Even if you do fewer miles, over time the belt deteriorates. It pays to change the timing belt, the injector pump belt and any other belts at the same time. A broken timing, belt can be very costly.
