Can the car run without antifreeze?

If the water temperature light on the dashboard is on, you need to add antifreeze in time, otherwise it may damage the engine.

The main functions of antifreeze are as follows:

1, which plays an anti-corrosion protection role for cooling system components.

2, prevent scaling, reduce the radiator temperature.

3. Ensure that the engine can work within the normal temperature range.

Therefore, when the antifreeze is insufficient, it will directly affect the heat dissipation effect of the water tank. When the water temperature is too high, the red water temperature light on the dashboard will light up. If the engine does not stop running, it may lead to engine cylinder pulling damage.

The replacement period of antifreeze should be subject to the manufacturer's instructions, generally 2 years or 40 thousand kilometers, and the longest is 4 years or 60 thousand kilometers. There are a few automobile manufacturers who support life-long replacement of antifreeze and only need regular inspection. Due to the poor fluidity of this antifreeze, it is necessary to pay attention to whether the circulating heat dissipation of the cooling system is normal.

Usually you need to pay attention to the position of antifreeze, and you must keep it between the lowest value and the highest value.
