Does anyone know what happens to the antifreeze? Does it burn off eventually? i haven't noticed any sweet smell vapors coming from the engine, and there aren't any leaks, yet every so often i have to top it off since it gets pretty low... usually when my heater stops working i have to add more fluid. I have no idea where it could be going.

S,
Our 96 bronco's coolant recovery tank weeps a bit of fluid at times. I add an ounce to 3 ounces about 3 times a year to get it to the level line on the tank. then at times, after a week or so I see the fluid slightly above the line!
I asked about this weepage in the ford-trucks MB and found many others experience the same.

Another thing could be a head gasket; do you see any signs of coolant in the oil? Or smell any coolant in the exhaust; hope it's not this!
