If you are not loosing any coolant then it is more than likely condensation, caused by short driving trips. A good long trip will help remove this. However, if you are having to add coolant, then you need to have it looked at by a professional. You may have coolant entering the lubrication system. This can be very serious. You may have a leaking head gasket. It will only get worse.
