I second that motion to get the water pump from the dealer..at least check the prices. I've got your car and had to replace it @98K. A chicagoland dealer price was $70ish with core exchange. Not bad. I don't remember it being real hard but I do remember the bolts were different sizes, so my brother and I stuck them in a box (in a pattern) as they came out so we got them right going back in. Good luck.
