The water temperature sensor or circuit is faulty, or there is a serious water shortage. Some engines are filled with long-term coolant. After working for a period of time, the water tank cover should be opened for inspection. When water stains, rust and sediment appear in the water tank, the coolant should be replaced in time.
Wait until the engine temperature drops before opening the cover and adding coolant. If you are pressed for time, you can first cover the water tank cover with a damp cloth, then wrap your hands with a wet towel, and then slowly open the water tank cover.
Notes
When adding water, if water is spilled on the engine’s spark plug hole seat, high-voltage wire jack, or distributor, it may have an impact on sparkover; water splashing on the transmission belt It may also cause it to slip; spilling onto the body may cause the 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 reactions, generate precipitation or bubbles, and reduce the use effect.
