I started to smell coolant when I would get out of my car, it never did over heat. So I took a flashlite and pointed it into the radiator resivor to light it up and it was almost empty. Dropped it off at the dealer and they called me saying my thermostat is stuck closed and I have a very small leak on the top radiator hose. Went ahead and changed the bottom radiator hose also.
