Information
As long as you are driving to work, traffic jams are unavoidable on the road and idling for a long time. This is the problem of poor engine heat dissipation. So how should we solve it?
Engines and air conditioning systems are not heat-dissipating, causing the water temperature to be too high, which will cause the following failures:
1. In poor traffic-traffic jam or long idling, the engine water temperature gauge shows too high, the electronic fan works for too long at high speed, the engine noise increases, and the fault is most obvious when the air conditioner is turned on when the temperature is too high.
2. When the air conditioner is turned on when the temperature is too high, the idling speed is unstable and the speed fluctuates too much, the acceleration is weak, and the engine makes abnormal noise.
3. After a hot car is turned off for more than ten minutes, it is not easy to start the car; when a hot car is running, it will sometimes turn off automatically.
4. The air conditioning refrigeration temperature is very cool when the car is cold, and the cooling effect of the air conditioning is not obvious when the car is hot; and there is a large resonance hum in the air conditioning system.
5. When the hot car is idling, the air-conditioning compressor clutch is frequently or even disconnected, causing the air-conditioning of the hot car to not be cooled.
The car engine and air-conditioning system have poor heat dissipation, causing the water temperature to be too high, and the following failure phenomena and solutions will occur:
1. In poor traffic-traffic jam or long idling, the engine water temperature gauge shows too high, the electronic fan works for too long at high speed, the engine noise increases, and the fault is most obvious when the air conditioner is turned on when the temperature is too high.
Solution: After the car is hot, check the water return of the return pipe at the upper end of the antifreeze storage tank. If the return water is not smooth or blocked, the water temperature will be too high.
Reminder: Don't blindly disassemble and replace parts during maintenance.
2. When the air conditioner is turned on when the temperature is too high, the idling speed is unstable and the speed fluctuates too much, the acceleration is weak, and the engine makes abnormal noise.
Solution: Check whether there is too much dust between the condenser and the water tank, and clean it thoroughly with high-pressure air to ensure that the water tank and the condenser have good heat dissipation performance.
Reminder: usually pay attention to wipe the dust between the condenser and the water tank.
3. After a hot car is turned off for more than ten minutes, it is not easy to start the car; when a hot car is running, it will sometimes turn off automatically.
Solution: When the car is hot, check the temperature difference between the upper and lower water pipes of the water tank. If the temperature difference is too large, you need to check the opening of the thermostat and whether the water pump has a rotation speed failure.
Reminder: The temperature difference between the upper and lower water pipes of the water tank should not be too large.
4. The air conditioning refrigeration temperature is very cool when the car is cold, and the cooling effect of the air conditioning is not obvious when the car is hot; and there is a large resonance hum in the air conditioning system.
Solution: Due to the irregular addition and replacement of antifreeze, the engine water channel and water tank will be blocked in advance and the water temperature will be high. The antifreeze is replaced once every two years, and original parts must be used when replacing and adding.
Reminder: After adding water to the engine cooling system, or the concentration of the added antifreeze exceeds 60%, the water temperature will be too high.
