Hi, I just registered and have a question. I own a 1996 Mazda 626 4cyl 2.0l and recently it began to overheat. The engines heat level got att the way right in about 15min. I didn't notice any leaking until I checked my radiator coolant which I noticed was empty. I filled it but it was still getting hot until I noticed a bit of a leak nothing big though. After a day I noticed a steady leak when the car was on. I had someone come to check it out then and the leak is on the right of the car (passenger side) but nowhere else. They suggested it may be the water pump. One mechanic said it would be $200 to install and $80 for a pump, seeing as there is no way it cost $200 to install a pump, I was wondering if anyone had and links or knowloedge of this and if I could do it myself. I don't have much knowledge of a car but do have common sense so if anyone has a manual or links I would appreciate it. I have searched some but I really need to fix my car soon.

Thank you very much for any help/information.
