The water temperature of the car is very high, but the wind blown out is very cold. What happened?

When the water temperature of the car reaches the specified value, it will give a signal to the sensor, and through the judgment of the sensor, it will give a command to the fan to tell it to rotate and take away the hot air, thus reducing the temperature of the water tank.

There are many reasons for the high temperature of the water tank, and the sensor is an important part. If the sensor is damaged, it needs to be replaced immediately.

Methods to prevent the water tank from overheating:

1, radiator should not be in contact with any acid, alkali or other corrosive substances.

2. It is recommended to use soft water and soften hard water before use to avoid internal blockage and scaling of radiator.

3. When using antifreeze, in order to avoid radiator corrosion, please be sure to use long-term antirust antifreeze produced by regular manufacturers and in line with national standards.

4, in the process of installing the radiator, please don't damage the radiator belt (film) and hit the radiator, to ensure the heat dissipation ability and sealing.

5. When the radiator is completely drained before adding water, turn on the drain switch of the engine cylinder first, and then turn it off when there is water flowing out to avoid blisters.

6, in daily use should always check the water level, stop using water after cooling. When adding water, slowly open the water tank cover, and the operator's body should be as far away from the water inlet as possible to prevent high-pressure steam from spraying from the water inlet and causing burns.

7. In winter, in order to prevent the core from being damaged due to freezing, such as parking for a long time or indirectly, all the water should be drained with the water tank cover and the drain switch.

8. The effective environment of standby radiator should be kept ventilated and dry.
