Should the availability of a number of conditions to ensure the best performance of the engine, such as the type and quantity of the recommended oil from the vehicle manufacturer, not less important for the use of coolant instructions, because the energy in the engine generated from fuel combustion worketh than the amount of large heat, if in excess of the allowable limit its lead to badly damaged the engine.
To obtain the highest efficiency of the engine, must be maintained in proper operating temperature degree. And disposed of degrees excess heat through the engine cooling system, each designed using air as an intermediary for dispersing excess heat, and the most commonly used use coolant, passing cooling around cylinders means, to bear degrees excess heat to the water cooler that transports heat from the coolant to the atmosphere.
And the cooling liquid is a mixture of water and antifreeze, because the water is able to absorb heat more than any other means of another, but can not use water only as a liquid cooling, because the boiling point of 100 degrees Celsius at sea level, and freezes when ° C zero, so address water to rise above the normal boiling point, and address as well as against freezing, if water freezes occurred, the size of more than about 9%, which can easily cause a crack in the engine or the water cooler.
The coolant several functions:
1. Heat transfer from the engine to the water cooler.
2. protects the engine and cooling system from rust.
3. prevent freezing in cold weather.
4. Heat the cooling of corrosion because it contains lubricant system.
It is recommended that all companies using the material as a basis for ethylene glycol coolant, which contains 50% water, ethylene glycol and 47%
Additions and other 3%.
Regardless of the manufacturer of liquid cooling, or color, but all refrigerants and one in the installation by 97%, and the only difference in additions and color, to help in determining its kind.
