If memory serves, the water pump, the timing belts, and a couple of other things are REALLY deep in the innards of most cars. You might want to consider having your timing belt changed while they are in there. It's expensive to get to where you *can* replace the water pump and the timing belt, but once you're there, they are both really cheap to do.
Had the timing belt taken care of at 90kmi, and he said it's still in good shape. They recommended the thermostat though, as it had some corrosion on it, so that got replaced as well. Finished it off with a full coolant system flush and leak check, and it's good to go again.
Ask about what else can be done...

Yeah, I like to do batch maintenance as well. :)
