Keep a close eye on the coolant level.
I had a 3.0 taurus that had a VERY slow head gasket leak. Hardly noticeable. When I had no heat, in WI, wintertime is when I found out. Replacing the thermostat and flushing the cooling system gives you a fresh start. My Taurus never overheated or showed high temperatures, although the gauge is a good place to monitor.
When you do have it flushed, have it done by a mechanic and have them "pressure test" your cooling system. A drop in pressure when testing will tell him there is a leak and then help you find it.
