Kerson & Richard, I’d be willing to bet that your actual problem(s) are merely the lack of “Coolant” (aka anti-freeze) in your vehicle but rather having only [and solely just] water. Let me explain. Water [by itself] boils at 100 degrees while a vehicle engine’s normal operating temperature is much higher (i.e. a previous car of mine had the a thermostat opening temperature of 165 degrees . You should look up the opening temperature of your vehicles thermostat. When anti-freeze/coolant is added to the water, it changes the boiling point and freezing temperatures of the [water] aka coolant. So simply put, with ONLY water in your radiator/coolant system, it is BOILING [evaporating] by being heated up to such a high temperature [above waters boiling point of 100 degrees]. Most vehicles coolant system have safety features in which allow high and/or excess ‘pressure’ to escape. It surprises me that I have not come across anyone mentioning this let alone adequately explaining it, so I hope my explanation will help many with this issue, as I suspect there are many whom being cheap and/or unaware of the consequences, only put/fill the radiator with water..
