What should I do if the car water temperature is too high? The water temperature of the car is too high, and the air conditioner does not cool.

1. First of all, don't turn off the engine immediately after finding that the water temperature is too high, because there are many reasons for the high water temperature, but there is probably only one fault at a time. If all other functions are turned off, the water temperature will always be too high, which will damage the engine. The accurate way is to stop at idle speed, open the hood, turn on the warm air, dissipate heat as soon as possible, and pay attention to stop in a cool place. Next, we need to check whether the coolant is sufficient. This situation is likely to be that the owner usually forgets to add it in time. It is important to note that the owner must choose the same brand and model products when adding coolant, otherwise chemical reactions may occur due to different components, leading to the failure of antifreeze. 3. Then, let's see if the cooling fan works normally. The failure of the cooling fan will cause the heat generated by the automobile engine running at medium and high speed to be transferred to the antifreeze, which will not be cooled in time, thus causing the temperature of the antifreeze to rise. If the fan gets stuck or the fuse burns out, it can be solved as soon as possible after the power failure. If it is a wiring problem, it can only be handed over to the professionals in the 4S shop for repair. Extended data:

Automobile water tank function:

The function of the cooling system is to dissipate the redundant and useless heat of the engine, so that the engine can run at room temperature at various speeds or driving conditions.

The water tank is the heat exchanger of water-cooled engine, and the normal working temperature of the engine is maintained by air convection cooling. Once the engine cooling water in the water tank boils and vaporizes at high temperature and the pressure exceeds the set value, the water tank cover (A) overflows to release the pressure, reducing the cooling water and preventing the cooling system pipeline from bursting.

When driving at ordinary times, pay attention to whether the pointer of the engine cooling water thermometer on the dashboard is normal. Other problems, such as engine cooling fan failure, may lead to engine cooling water temperature increase or cooling system pipeline leakage, and may also lead to cooling water reduction. Please pay attention to whether the cooling water reduction amount and cycle are normal before adding distilled water.
