Due to the congenital defect that the traditional coolant: water and aqueous antifreeze cannot meet the heat dissipation of the engine:

1. Water will freeze at 0 ℃ and boil at 100 ℃. Freezing will explode the engine water tank and cylinder block, and boiling will overheat the engine until it is paralyzed.

2. When the engine temperature reaches above 80 ℃, water bubbles should begin to appear on the cylinder wall. Water bubbles form a bubble heat barrier layer on the surface of the cylinder to prevent heat dissipation inside the engine. Water bubbles are generated and broken endlessly on the metal surface of the engine block, and the cylinder block is lost with the effect of dripping water through stone – this is cavitation.

3. The local temperature inside the engine is too high, the tendency of precombustion and detonation increases, increases vibration and noise, greatly reduces the engine performance and efficiency, and forms anhydrous fuel consumption.

4. The electrochemical corrosion of water under the action of electrolyte and the generation of rust and scale aggravate the aging speed of the cooling system and reduce the heat dissipation performance.

5. When the engine temperature reaches above 80 ℃, the water vapor, water bubbles and water expansion will increase the internal pressure of the cooling system. In this way, it not only catalyzes the aging speed of the cooling system, but also makes it gradually unable to ensure the speed required for normal heat dissipation due to corrosion. Therefore, the heat dissipation defects of aqueous antifreeze are summarized as follows: the heat dissipation performance is limited and can not hold the overheat peak; Gradually aging the engine, increasing the calorific value of the engine; Gradually aging the cooling system to reduce or increase the heat dissipation capacity.

Lack of liquid in the cooling system: the radiator is cracked, there is hole leakage or the cylinder water jacket is damaged, resulting in the outflow of cooling water; The water inlet and outlet pipes are damaged and leaking; The switch is damaged, resulting in liquid leakage.

Solution: stop the leakage of leakage liquid. If it is serious, replace the radiator; Replace the water inlet and outlet pipes; Replace the switch.

Too high engine coolant: too little cooling water; The power transmission belt of the fan is broken or too loose to give full play to its function; There is too much scale on the cylinder water jacket and radiator, which affects the heat dissipation performance; Abnormal operation of water pump leads to poor water circulation; The radiator fin is dumped or the connecting hose is sucked; One of the water temperature gauge and sensor fails or both fail.

Solution: add cooling water; Replace the drive belt or tighten the conveyor belt; Clean the cooling system; Repair the water pump; Check the water outlet pipe. If it is deflated, eliminate it and repair the radiator fins. Check the water temperature gauge and sensor.
