take the belt off and grab the w/p pulley, see if it has side to side play, if so its shot.

if your losing coolant fast. id think one of the coolant elbows blew out. you have 2 if your a 99 or newer car, the 2 nd one is hiding behind the water pump

see right above the power steering pump and behind the water pump that tube that turns in, this is a 98 so its a cast elbow, 99 and up has another plastic elbow there, as well as the one at the top of the pic.
