After you drain coolant remove the larger hose at the bottom of over flow tank and the 2 smaller hoses at the top. remove the 1 bolt holding the overflow tank on and remove tank. Next take serpentine belt. Take the 4 bolts off holding on the water pump pulley and remove pulley. Next remove the 5 bolts holding water pump in. Clean water pump housing of old gasket and clean with alcohol or paint thinner to remove any residue. Use a small amount of RTV sealant along with a new gasket and put in the 5 bolts tightening them by hand. Next tighten the bolt a quarter turn at a time until tight.put on pulley, put in overflow tank and attach bolt and 3 hoses .

How do i replace the water pump on my 1999 pontiac grand am?

I'm pretty sure the water pump on your car is buried in the block, making it very difficult to replace. You might get a Chilton or Haynes manual and follow procedures. That should get you where you need to be.. If you had a Ford there would be no problems.... ok.. just kidding. Good luck.
