What is the recommended timing belt change interval for a [DSM]?

All DSMs should have their timing AND balance shaft belts changed every 60,000 miles (90,000 km). Many engine-destroying belt failures are really the fault of the balance shaft belt, rather than the main timing belt.

Most people find it convenient to change all the belts at once. There are five belts on 1G DSMs (and probably on 2Gs, as well) as well as tensioners and pulleys.
