The car's water tank is out of water or the water temperature is too high, and the liquid level indicator light on the instrument will light up.
As an important component of the water-cooled engine cooling system, the water tank can absorb heat from the cylinder and prevent the engine from overheating. Since water has a large specific heat capacity, the temperature then increases. the heat absorption of the cylinder is not very high. Therefore, heat from the engine passes through the cooling water liquid circuit, using water as a heat carrier to conduct heat, and then dissipates the heat by convection through large-area heat sinks. maintain proper engine operating temperature.
When the car water tank is out of water, the water temperature rises easily. The light indicating that the water temperature is too highvee lights up. When the water temperature is too high, the warning light indicates that the water temperature is too high. The warning light will look like a The shape of the thermometer makes it very easy to judge.
Detailed information
The car water tank does not need to replace the cooling water frequently, but it does need to be replaced .
Ordinary family cars are usually replaced every two years or 40,000 kilometers. Of course, you can decide to replace it based on actual usage. If the vehicle is used intensively, it must be replaced first.
If the antifreeze is not changed for a long period of time, the quality of the antifreeze will change, reducing its inherent rust-proofing quality, and the radiator, pipes, etc. will become damaged. will be damaged. This will also affect the boiling point and freezing point settings, as well as the eAntifreeze effect or cooling effect.
For further details, please refer to the vehicle manual, which details the replacement cycles for vulnerable vehicle parts and different oils. Following the above is the most scientific and appropriate method.
