The cooling system in the vehicle for optimum engine temperature, and supports it at a constant level, This temperature is about 100 degrees Celsius. And in order for it to function correctly, constant monitoring of the technical condition is required, from the correct selection of antifreeze to checking its level and basic parameters.
What is Antifreeze?
Antifreeze is a liquid, which transports thermal energy between the engine and the radiator, whereby the extracted order to 30% heat, derived from combustion of fuel. also antifreeze:
- It protects against freezing, cavitation and boiling.
- Corrosion protecting elements of the engine and cooling system components.
- Thanks to him, is not formed and does not accumulate scale, contributing to plaque formation in the cooling system.
- As well as other liquid has a high heat capacity.
Antifreeze is half water, other components are alcohol or glycol, as well as inhibitors for corrosion protection. These components, liquid retains a high specific heat and protects the cooling system. Typing in a search engine “buy antifreeze cues” вы найдете как готовые жидкости так и концентраты, which should be mixed with distilled water. Existing fluid divided into universal and with increased cooling efficiency.
Before you buy…
There are a few important tips, which is worth reading before you buy antifreeze:
- If the liquid will be too little concentrate, t. it is. below 30%, the risk will be increased: freezing winter and cooling system of corrosion.
- If a, in turn, will concentrate too much, that is above 70%, it will increase the risk of overheating the motor, causing serious damage.
- Choosing coolant you should pay attention to the warranty and certificates, confirming the quality of.
- If you find yourself in a situation, when the liquid level is very low, and you will not be able to buy and top up, то временно ее можно заменить водой. It must be distilled water. But at the first opportunity you will need to replace it with antifreeze.
- Antifreeze should be replaced every 2 or 3 of the year, regardless of, the product of the manufacturer you are using. And all because eventually each liquid loses its properties, and the car has to be protected from the occurrence of the fault.
- Costs, related to the acquisition of the coolant is not high - a liter costs an average of 2,5 to 4 dollars depending on the brand and quality.
Does the color of the liquid matter?
In the automotive market, there is antifreeze in many color variations. but, it has nothing to do with his appointment or features. Where did this stereotype? In the early nineties liquids producers began to use colorants, thus highlighting their products.
Most often, the fluid occurred in those years in a green or blue color, produced by IAT technology - Inorganic Additive Technlogy, то есть содержащие неорганические добавки. Эта технология создавала защитный барьер для всех компонентов системы охлаждения, благодаря чему защищала ее от коррозии и отложения накипи. Однако содержание силикатов снижало качество этой жидкости. Therefore it became necessary to replace it more often than once every two years.
In turn red, pink, blue, orange or purple color – belonged liquids, made on OAT technology - Organic Acid Technology. They had an addition of organic acids, and did not contain silicates. It was much more modern technology, than IAT - from it appeared nearly twenty or more times thinner than the corrosion layer, which facilitated the transfer of heat from the engine to the fluid and fluid from the radiator to the wall.
But that was before, а сегодня каждый производитель может использовать красители любых цветов лишь бы продать свою продукцию. На сегодняшний день нигде четко не сказано, that color is the only indication of a certain type of liquid. Coloring is also a relative type of protection, against counterfeiting.
