Every 60-80,000 miles and most definately replace the water pump and all belts that are involved as the most expense is of course the labor and you are naturally paying for that when they go in to replace the pump so it only makes sense to add on the parts that are easily installed once the timing belt is removed.
Good luck hope this helps.
