HMSANTIAN FRIEND These vehicles that have a motor with a camera or aluminum butt such as the Ford Fiesta 2005, unlike an old vehicle that has engine with a camera or cast iron butt such as Ford Maverik for example, they have a cooling system based on the principle of thermodynamic equilibrium that is to say control temperature in pressure function. I explain: in a maverix, Ustec uses water coolant as a waterfront and can travel more than 100 km without the radiator lid and how the temperature is controlled by the marker, it will take more than three hours to heat so that you can reach anywhere traveling that distance.
In a 2005 Ford Fiesta you cannot do that because immediately the engine begins to heat and not travel 10 km without presenting problems of oil evaporation and overheating.
For that reason the refrigerant used of factory that brings the vehicle, is not water but a color liquid. Preferably red, yellow or phosphorescent green. This is right to be. It is to detect steam leaks in hoses, radiators and cooling pipes that cannot be persecutible if the steam is water. The principle is as follows in this vehicle: if there are steam leaks, not liquid. The low pressure and the temperature increases immediately. If there is no loss of pressure it is because there are no leaks and a pressure-temporeure balance is established that will be in about 80 ° C. If you are using water, change the color refrigerant to observe in the places where you appear a stain there will be the steam leak. No liquid. It can be in the main radiator, in the heating, in the hoses including those that enter the acceleration body, or in pipes that in some vehicles are of brass material. Greetings I hope it is useful to you
