Yes it will cost about $550-$575. That includes a new water pump, coolant, pullys, timing belt and tensioner, and a new serpentine belt, plus labor. Not a bad deal if you ask me.
If your timing belt/tensioner and/or serp. belt are fine then I guess subtract some of the cost then, but if you havent had them replaced in a while then you should because your shop may not charge you labor because the old ones must come off anyways.
