For the first time ever in the 10 years I have owned my car, the guy changing my oil said that he had to top off my Dex Cool in the bottle to the right of the engine. He said I needed to have it checked out. Two years ago I had all my Head gaskets and manifold gaskets changed out, so I know the water isn't coming from there. Could there be a small leak in a radiator hose or the radiator?

Usually, if there is a leak, you will smell it or see steam. Some coolant can evaporate under normak usage; however, if you are concerned, check the hoses, waterpump, heater core hoses... to see if there is evidence of a leak. Also, if this is a 3.1L V6, recheck the intake gasket. This is a common problem with the engine.
