Guangzhou Automobile Chuanqi gs5 is boring if it is broken. What is the rapid rise of water temperature?

The main reasons for the high water temperature of automobile climbing are as follows:

1. The engine and air conditioning system have poor heat dissipation, resulting in the following fault symptoms when the water temperature is too high:

1. When there is traffic jam or idling for a long time, the engine water thermometer shows too high, the electronic fan works in high gear for too long, the engine noise increases, and the air conditioning fault is the most obvious in hot weather;

2. Air conditioning is turned on in hot weather, the idle speed is unstable, the speed fluctuates too much, the acceleration is weak, and the engine has abnormal sound;

It is not easy to start the car again after the hot car is turned off for more than ten minutes. Hot cars sometimes turn off automatically when driving;

4. The air conditioning refrigeration temperature is very cool when the car is cold, and the air conditioning refrigeration effect is not good when the car is hot. Moreover, the air conditioning system has a loud vibration buzz;

5. When the hot car is idling, the clutch of the air-conditioning compressor is frequently sucked off or even disconnected, resulting in that the air conditioner of the hot car cannot be cooled.

Second, the solution of the fault has the following methods:

1. Check whether there is too much dust between the condenser and the water tank, and thoroughly clean it with high-pressure gas to ensure that the water tank and condenser have good heat dissipation performance;

2. When the car is hot, check that the temperature difference between the upper and lower water pipes of the water tank can't be too big, otherwise, check the opening of the thermostat and whether the water pump is slowing down;

3. After the hot car is started, check the backwater of return pipe at the upper end of antifreeze storage tank. If the backwater is not smooth or blocked, the water temperature will be too high. Please be careful not to blindly disassemble and replace parts during maintenance.

4. Due to the irregular addition and replacement of antifreeze, the engine water channel and water tank will be blocked in advance, resulting in high water temperature. Antifreeze should be replaced once every two years, and original fittings must be used when replacing and adding. Please note that the water temperature will be too high after adding water to the engine cooling system, or if the concentration of antifreeze added exceeds 60%; 5. Because the high pressure at the high pressure end of the air conditioning system is too high; Excessive filling of air conditioning refrigerant or air conditioning refrigeration lubricating oil; The self-regulating function of the internal self-regulating air-conditioning compressor fails, resulting in high pressure; There is also the blockage of the air conditioner condenser, which will increase the load of the engine and consume the heat dissipation performance of the cooling system, leading to the failure of high water temperature.
