Why does the Emgrand GL dissipate heat so slowly?

[StHadley]

Emgrand GL slow heat dissipation may be caused by excessive dust between the condenser and the radiator, a large temperature difference between the upper and lower radiator hoses, or poor return flow in the upper return hose of the coolant reservoir. Check if there is excessive dust between the condenser and the radiator: Use high-pressure air to thoroughly clean, ensuring the radiator and condenser have good heat dissipation performance. Check the temperature difference between the upper and lower radiator hoses when the engine is hot: If the temperature difference is too large, it is necessary to check the opening of the thermostat and whether the water pump has a speed loss fault. After the engine is hot, check the return flow in the upper return hose of the coolant reservoir: Poor or blocked return flow can cause the water temperature to be too high.
