What are the reasons why Geely Emgrand ec7 heater is not hot?

Emgrand ec7 is a global quality car produced by Geely Group and the first model of the Emgrand brand. When driving in the cold winter, air conditioning heating is very important. What are the reasons why Geely Emgrand ec7 heater is not hot?

The reason why the Geely Emgrand ec7 heater is not hot is that the small heater box is blocked, the heater motor does not work, the thermostat does not open or does not work, and the engine water tank temperature is not high enough. The working principle of a car heater is very simple, that is, the engine water flows through the heater's radiator through the valve, the fan starts, and the engine heat is dissipated into the car. It can work at any temperature and the heat dissipation can be adjusted. The principle is the valve. This valve is related to the temperature control switch on the air conditioning control panel. By adjusting the opening of the valve, the water flow can be adjusted to achieve the purpose of adjusting the temperature.

When using the car's air conditioner switch in winter, do not turn it on as soon as you get into the car. The correct approach is to preheat the engine first, wait for the engine temperature pointer to reach the middle position, then turn on the heater air switch, and at the same time set the air circulation to external circulation, so that the cold air in the car can be discharged outside the car, and wait for 2-3 minutes. , and then change the empty air circulation to internal circulation.
