Maintain the temperature of the engine is important; Overheating is fatal and costly to repair. Therefore, a good cooling is vital.
In the automotive mechanics, the cooling system is responsible for regulating the temperature of a car. Its main objective is to dissipate the heat produced by the engine when it is in operation and to maintain it at an ideal temperature.
The element that has the cooling system to achieve this goal is the coolant, a mixture of glycol and water in equal parts.
Glycol water adds two important qualities for automotive use: the first to prevent the merger from freezing in climates with low temperatures. The second so that it does not reach its maximum boiling point. That is, if water normally boils at 100 ° C, glycol only reaches 90 ° C.
Now, water is better heatsink than refrigerant; however, this has additives providing the rust and corrosion of the mechanisms that make up the cooling system. While it is an important system performance engine, maintenance is not as rigorous: only if there is a fault in one of its components, attention must be paid to the level of the coolant.
If you change refrigerant – usually every 2 years – it is good to remember to do it with the cold engine. Never but you should never open the lid of the cooling system with auto hot if you do not want to go to the hospital for burns!
Significantly, you should always use the coolant recommended by the manufacturer. If an alternative is sought in the end, one should try to be one that gives guarantees, because it is well known that in this country has the custom of ‘pirate’ everything.
Not all refrigerants are the same. Although the sellers say yes, among the best known are:
Anticorrosive coolant: This liquid contains additives besides cooling corrosion preventing. The more concentrated it is, the better it will perform its function.
Antifreeze coolant: Ideal for countries with very cold weather. It will help prevent freezing of the liquid, if the temperature is near or below 0 ° C.
Distilled or Demineralized water: Because it does not contain minerals, it is perfect to fill the system – not fill- when the level is low.
Green cooling: the use of this coolant in engines with a long use and is recommended for corrosion.
