The water temperature of Wuling Glory has always been two grids, and it is not hot to turn on the warm air. What's going on here?

1, the temperature is not high, it is normal, and the general models are in the center line;

2, but too low is wrong. It should be caused by the thermostat being on all the time. It is necessary to replace the thermostat.

Thermostat state judgment

When the engine starts to run cold, if there is still cooling water flowing out of the water tank inlet pipe, it means that the thermostat main valve cannot be closed; When the engine cooling water temperature exceeds 70℃, there is no cooling water flowing out of the water tank inlet pipe, indicating that the main valve of the thermostat cannot be opened normally and needs maintenance. The thermostat in the vehicle can be checked as follows:

Inspection after starting the engine: Open the radiator filler cap. If the cooling water in the radiator is calm, it means that the thermostat works normally; Otherwise, the thermostat is not working properly. This is because when the water temperature is lower than 70℃, the expansion cylinder of the thermostat is in a contracting state and the main valve is closed.

When the water temperature is higher than 80℃, the expansion cylinder expands, the main valve gradually opens, and the circulating water in the radiator begins to flow. When the temperature indicated by the water thermometer is below 70℃, if there is water flowing through the water inlet pipe of the radiator and the water temperature is warmer, it means that the main valve of the thermostat is not closed tightly and the cooling water circulates prematurely.

Inspection after the water temperature rises: at the initial stage of engine operation, the water temperature rises rapidly; When the water temperature meter indicates 80, the heating rate slows down, indicating that the thermostat is working normally. On the other hand, if the water temperature continues to rise rapidly, when the internal pressure reaches a certain level, the boiling water suddenly overflows, indicating that the main valve is stuck and suddenly opens.

When the water temperature meter indicates 70℃-80℃, open the radiator cover and radiator drain switch, and feel the water temperature by hand. If both are hot, the thermostat works normally. If the water temperature at the radiator inlet is low, there is no water flowing out of the radiator inlet or a small amount of running water, indicating that the main valve of the thermostat cannot be opened.

The temperature controller that is stuck or not closed correctly should be removed, cleaned or repaired, and cannot be used casually.
