Some dealers say water pump does't need change, if good. Ditto with other belts.

Most auto technicians will tell you to replace anything that appears worn, leaking, or noisy. You have to take it on a car by car basis. I would also base it on mileage. The worst thing there is, is to do a timing belt (and nothing else) and then have to go back in there soon after because the water pump started leaking. Wasted time and money.
