Timing belt Options

[Niskyspy]

As of now my car has 94,000mi and I found out that the first owner never changed the damn timing belt (I asked him). Well now I think that I need to change the timing belt cuz he was supose to do it at 60,000mi. So I called up toyota and they gave a price quote on timing belt and water pump around 460$. But now there is a cupon which I can use to get them to change the timing belt (without changing water pump) for 286$. I think its a pretty good deal. But my question is, should I replace the water pump now. I have 1.8 liter engine and I think that the water pump is not driven by the timing belt and that its diven by (generator/ac pump) belts. So I was thinking just to change timing belt at toyota dealer and if my water pump fails do the water pump myself cuz its not too much work. So please give me some feed back on this.
Thanks

the water pump is normally run off the timing belt. its really a good idea to do the belt, pump and thermostat at the same time. if the pump goes in the future, it could be the end of your motor.

i would take that cupon in with u and try to get a better deal. if they are willing to get to the belt for 286$ then they shouldnt charge you a whole lot more to swap out the pump, since they will be working in that area anyway
