Disappearing coolant

2011 LTZ 57k has a disappearing coolant issue, have had to refill the reservoir twice now in around 30 days. Each time it has taken over 1/2 gallon. What am I looking for?
Thanks Rick

Water pump leaks are very common (you'll see coolant residue around the upper pulley on belt side of the engine), as are leaks at the hose that connects from the coolant take to near the top of the engine. Sniff around under the hood with the car good and hot and you'll probably find something.
