How do you replace the water pump on a 1998 Chevy Malibu 3.1L automatic?

I think theres 4 bolts. remove pump. clean surface good, apply small light coating of form gasket on gasket, place onto, align holes, install new pump, install is reverse of removal. its not a hard one to do at all - i'v seen WAY worse
