Your best answer would be to consult your manual for the vehicle under "maintenance tables" (in the back of the manual). Otherwise the belt is typically replaced at every 60,000 mile interval. To verify this I would recommend you call a local auto parts place, tell them the type of vehicle and engine size and then ask them how often the belt should be replaced. Again, I recommend you consult your manual. Note: there is only one belt and it is commonly referred to as a serpentine belt.
