What is the problem that the uphill temperature of Futian Cummins 3.8 engine is too high?

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 failure 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;
