Lao Liu said why the total heat of the car (41) is after the car is boiled?

[Xiagong Chusheng original] Some vehicles suffered from high temperature engine failure and the engine was seriously deficient in water (coolant), causing serious cylinder pad damage. After repairing the engine, many drivers found that the vehicle was easily reheated again. Excluding the problem of the engine itself, there is a need to pay more attention to the phenomenon, that is, water tank "reverse water." Water tank reversed water is misunderstood by many people as a precursor to damage to the cylinder mat, but there is often another problem that can easily be overlooked - the water tank is blocked.

The causes of frequent high temperatures are mainly in the engine cooling system. After the scales such as the cylinder block and the cylinder head come off, they block up to the water radiator radiator and are difficult to remove by ordinary methods, resulting in poor circulation of the engine cooling system.

The principle of causing jams is similar to that of teapots. In the boiling water process, teapots are accidentally dried. The metal and scale in the bottom of the kettle are physically changed by heat and the scales fall off. In the same way, in the absence of cooling water in the engine, the scale and impurities deposited on the surface of the cylinder will fall off, and eventually the coolant will circulate to the upper part of the water tank, causing the radiator water channel to be blocked.

Usually this type of plugging, large particles of impurities, using a general chemical cleaning agent is difficult to completely remove, you need to professional tank maintenance department. The dismantling tank is thoroughly cleaned, which is the “through water tank”. The tank cleaned by the artificial physical method works best.

Xiaobian reminds:

1 Often high-temperature vehicles need to pay special attention to the cleaning and maintenance of the radiator surface. The heat sink on the surface of the radiator must be repaired in time to maintain ventilation.

2 It is strictly forbidden to flush the surface with high pressure water jets when washing cars.

3 Normal external maintenance of the tank should be done with a neutral detergent. After brushing the surface, rinse with water. If necessary, dry it with compressed air. Check the insect net during installation.
