You will want to get your water pump changed that the same time, because if that goes, it's the same process to rip the engine apart and it only makes sense to pay for that once instead of twice. If you neglect replacing your timing belt and it goes, you are then faced with a whole host of problems, because it will make many other things go very wrong.
