01 Low freezing point
Antifreeze, as its name implies is to prevent frozen liquid, which requires antifreeze has a relatively low freezing point, the lower the freezing point, the better the antifreeze effect of the product! According to the author's knowledge, the highest freezing point of antifreeze can reach -45 centigrade! Consumers can choose the appropriate antifreeze according to their own climate conditions.
02 High boiling point
In fact, the name should be antifreeze antifreeze coolant, many owners will ignore the "cooling" two words, not only the antifreeze antifreeze, but also shoulder the responsibility to prevent tank "boil". Now the quality of Antifreeze on the market boiling point is generally about 105 degrees celsius.
03 Anticorrosion
The engine cooling system consists of metal, rubber and plastics composed of different materials, life in general more than 10 years, but there are many owners found their car after two or three years on the Water Leakage, probably because of the use of low-grade antifreeze sake. So, you must buy antifreeze in regular channels!
04 Anti fouling
Many drivers release antifreeze in summer and tap water. There are many minerals in the tap water. After heating and evaporating, these minerals deposit in the metal surface. Due to the formation of scale, resulting in heat generated by the engine can not be timely sent to the antifreeze, cylinder temperature, the clearance between the cylinder and the piston cylinder and the gas ring caused by improper wear, serious when can make the piston stuck, a fatal damage to the engine. If the scale in the water tank, it will influence the radiation effect of the radiator, leading to elevated temperature and boil, and antifreeze quality is made by using distilled water, and adding anti scaling additives so that it does not produce any scale.
05 Attention model
The different types of antifreeze must not be mixed, so as not to cause chemical reactions, precipitation or bubble, damage to the rubber sealing ring, resulting in water pump seal and weld leakage.
How to replace antifreeze
The first thing to do a comprehensive inspection, to see whether the pipe leakage traces, focus on examination of the five tubes, five tubes with five connecting various parts of the interface and the name, antifreeze is flowing through the five tube, were assigned to different parts of the car will play a role; and then release the old antifreeze with water, cleaning liquid channel.
Let the water flow continuously through the engine cooling system, and then let the car idle for 3~5 minutes, let the water cycle. Start from the outflow of water in the water a little pale pink, until the flow out of the water is clean; water about 1 hours later, the new coolant from the water tank (radiator) pipe join, this is the way to make the antifreeze rapid inflow water tank.
Then another bucket adding antifreeze antifreeze antifreeze added to the tank, tank quickly filled up the car ignition, wait 10 minutes, then the cooling system with the exclusion of air, liquid level decreased, then the antifreeze added, fill up to the max marking tank so far.
