First, you will have to buy the special water pump removal tool available at most auto part stores for about $35. Next, drain the cooling system from the radiator and remove the upper & lower radiator hoses. At the lower radiator hose connection, there is a housing with 5 bolts. (before you go that far, remove the drive belt off of the water pump pulley by inserting a 1/4" ratchet into the tensioner to remove the belt)
Remove those 5 bolts and separate the housing. You now have access the the water pump. With the special tool & a 1/2" ratchet or breaker bar, turn clockwise to remove the water pump. The remainder of the steps is the reverse of removal. Make sure you use a new o-ring on the new water pump and put RTV sealant on the housing to prevent leaks. While you're at it, it's not a bad idea to replace your thermostat and hoses to make it a complete, thororugh job.
