Automobile engine and air-conditioning system have poor heat dissipation, resulting in high water temperature, the following kinds of fault phenomena and solutions will appear: 1. When the traffic is poor - traffic jam or long idle, the engine water temperature indicator shows too high, electronic fan high gear working time Too long, the engine noise increases, and the air temperature is too high. Related reading: Scientific and reasonable maintenance of the car to help you save unnecessary costs to avoid the ten errors in the car maintenance Solution: After the hot car, check the water return of the return pipe on the top of the antifreeze storage tank. If the return water is not smooth or blocked, the water temperature will be too high. Reminder: Do not blindly disassemble and replace parts during maintenance. 2, when the air temperature is too high to open the air-conditioning, the idling speed fluctuations are too large, rapid acceleration and power, the engine has abnormal sound. Solution: Check whether there is excessive dust between the condenser and the water tank, and clean thoroughly with high-pressure gas to ensure that the water tank and the condenser have good heat dissipation performance. Reminder: Always pay attention to the dust between the condenser and the tank. 3. When the hot car is extinguished for more than ten minutes, it is not easy to start the car when it is started; sometimes the hot car will automatically turn off when it is running. Solution: In the hot car, check the temperature difference between the upper and lower water pipes of the tank. If the temperature difference is too large, you need to check the opening of the thermostat and whether the water pump has lost the speed. Reminder: The temperature difference between the upper and lower water pipes of the tank should not be too large. 4, cold air conditioning when the cooling temperature is very cold, hot air conditioning when the cooling effect is not obvious; and the air conditioning system has a large resonance buzzing sound. Solution: Due to the non-standard addition and replacement of antifreeze, it will cause early blockage of engine water channels and water tanks, and the phenomenon of high water temperature will occur. Antifreeze is replaced once every two years, and original parts must be used for replacement and addition. Reminder: After the water is added to the engine cooling system or the concentration of antifreeze added exceeds 60%, the water temperature will be too high.
