It's recommended that you replace the timing belt every 60,000 to 90,000 miles. It's not a hard and fast rule though. If you drive gently, you could probably get away with longer, but that might erode your peace of mind to do so, knowing that your timing belt is very near the end of it's lifespan and if it brakes it will cause major damage to your engine. I get really skittish at around 80,000 miles.
It's a big job to do, and since the timing belt and water pump are in the same vacinity, replace them both. Water pumps go bad too.
