What is the problem that the automobile instrument shows that the water temperature is high but the water tank is very cold?

It is a water temperature sensor or line failure, or a serious water shortage. Some engines are equipped with long-lasting coolant. After working for a period of time, the water tank cover should be opened for inspection. When water pollution, rust and sediment appear in the water tank, the coolant should be replaced in time.

Wait for the engine temperature to drop before opening the cover and filling the coolant. If time is short, cover the water tank cover with a wet cloth first, then wrap your hands with a wet towel, and then slowly open the water tank cover.

Matters needing attention

When adding water, if water splashes on the spark plug hole seat, high-voltage wire jack and distributor of the engine, it may have an impact on flashover; Water splashed on the drive belt may also cause the drive belt to slip; Sprinkling on the machine body may also cause the machine body to deform or even crack.

Antifreeze and its additives are toxic substances, please do not touch them and keep them in a safe place. Cause chemical reaction, produce precipitation or bubbles, and reduce the use effect.
