Well, here is how I do it.
If the timing belt needs replacing and the Water Pump is run by it, I won't do the job unless I replace the water pump. There is no sense in doing one and then possibly having to pay the same labor again to have the other done with a few of months.
This is how I look at the water pump and replacing the timing belt. The timing belt has stretched over the years and mileage, which in turn reduces the stress and tension on the old water pump. So, when new belt is put on it will create more stress and tension on the old water pump which will cause it to fail within about 6 months or less.
So, I feel the dealer is trying to make some extra money by only doing the belt and hoping within the next couple months or so you will need to water pump done.
Also I would make sure that all timing components that can be replaced are.
