loosing coolant location drivers side loose rattling sound by water pump belt on 2004 Cadillac DeVille DTS

losing about a quart a week of coolant around belt area

It very well could be a water pump. This job isn't too bad to do, but it does require a special tool, to unlock and lock the water pump during replacement. Get it fixed ASAP as these motors do not like to be overheated.
