The engine water temperature is not high, but there is little water. What is the reason?

☆ The engine water temperature is normal, indicating that the engine cooling system is working normally. A small amount of cooling water will not cause the engine water temperature to rise, but only when the cooling water is lacking to a certain amount will it cause the engine water temperature to rise.

Many reasons will lead to the reduction of cooling water in automobile cooling system, and the common one is water leakage at the upper and lower water pipes or water pipe joints of water tanks.

The upper and lower water pipes of the cooling system are all made of rubber, and the working temperature difference of these rubber products is very large. After long-term use, the rubber water pipe gradually ages, the elasticity decreases and cracks appear, so there will be cooling water leakage, but a small amount of cooling water loss will not affect the work of the cooling system.

The decrease of refrigerant may also be caused by the hot air system of air conditioning. The heat energy of automobile hot air comes from the cooling system of the engine. The common leakage of warm air circulation system is also the inlet and outlet pipes and water pipe joints of warm air water tank, and the reason is also the aging of rubber water pipes.

The third case of cooling liquid reduction is the failure of the water pump, such as the aging of the water seal or gasket, and the cooling liquid will be discharged from the drainage hole. If it is only oozing but not exposed, it is generally difficult to observe from the surface, and the decrease of coolant is not obvious. However, if it is not treated for a long time, many a mickle makes a mickle, which will affect the work of the cooling system.

In addition, the cylinder water jacket leaks, the water tank is damaged, the expansion pot is damaged or the water pipe is aging, which will consume the coolant. The lack of a small amount of coolant will not affect the operation of the cooling system. As long as it is replenished in time, the normal operation of the cooling system can be guaranteed, but this is only an indicator. If you want to solve the problem, you still need to find the source of the leak. In order to completely solve the problem of insufficient antifreeze.
