Check the coolant level. If you think that you have a leak, refill and mark it with a grease pencil or just a great eyeball on the amount. Recheck a couple of hours later to see if it has dropped. Now, it won't just evaporate, check underneath for drops.
If that is a dead end, the thermostat would be my next option.
