Automobile engine cooling system is an important component to ensure the normal operation of the engine. If the maintenance rate of engine cooling system is high, it will damage other parts of the engine and affect the overall working ability of the engine. Therefore, the maintenance of automobile engine cooling system is particularly important. So, how can we keep the automobile engine cooling system in good condition? Automobile beauty maintenance experts suggest that we should first understand the main components of commonly used water-cooled engines in order to correctly stack and protect the engine cooling system:

First, coolant, coolant refers to clean soft water, not all water can be used as coolant, and the more expensive the car, the higher the water quality requirements. For example, clear spring water, although clear and clean, contains a lot of minerals. If it is added to the engine cooling system, it will produce a lot of scale, which will affect the normal function of the cooling system. It can be seen that the quality of coolant is very important. Second, the cylinder water jacket is equivalent to the water channel around the engine combustion chamber. When the engine generates a lot of heat, the cylinder water jacket will play a cooling role. In an engine, water pipes and oil pipes are completely different and do not interfere with each other. If oil is found in the coolant, there are holes in the waterway and oil circuit. Once this happens, the temperature of the water thermometer will rise sharply. At this time, measures must be taken in time.

Thirdly, the cooling water tank and cooling fan, the cooling water tank looks like a honeycomb from the outside, this shape is to increase the cooling area of the water tank and enhance the cooling effect; Some cooling fans are installed at the front and some are installed at the side. When the car is driving at high speed, the cooling fan attracts the outside air and uses the natural wind to play a cooling role.

Fourth, the cooling water pump and thermostat, the flow of coolant in the cooling system mainly depends on the power of the cooling water pump; The thermostat can sense the working temperature of the engine. When the temperature is low, it seals the water in the water jacket and lets the water flow in the water jacket. When it reaches a certain temperature, it is opened again to let water pass through the cooling water tank for cooling. It is worth noting that the thermostat must not be removed, otherwise the engine will be too cold to start.

In order to correctly maintain the engine cooling system, we should know several common cooling system failures:

First, due to the poor quality of coolant, rust and scale often appear in the water tank. They are piled up at the joint and corner of the water tank channel, which hinders the smooth flow of water and leads to poor heat dissipation. If this happens, clean it in time and try to add clean soft water when adding water daily. The maintenance effect will be better if descaling and antirust liquid is used. It can quickly dissolve the scale, sludge and scale formed in the cooling system and restore the function of the cooling system. Rust lubricant, the cooling system, is also a good product. It can prevent the cooling system from rusting and corrosion, effectively inhibit the generation of scale, lubricate the water pump and thermostat, eliminate the abnormal sound of the water pump, protect metal parts such as copper, aluminum and tin, prolong the service life of the water tank, prevent the water tank from boiling, and make the engine work at normal temperature.

Second, water leakage, as long as it is a fluid, there is the possibility of water leakage. Once the cylinder water jacket leaks, the water temperature of the water thermometer will rise sharply. In this case, you must take necessary measures in time to avoid unnecessary troubles and slow down the generation of impurities in the cooling system.
