Why is the golden cup sea lion hot? The temperature is normal at 100, and it starts to heat at 120.

There are many reasons for poor heat dissipation, such as: the cooling system (water tank and pipeline, the waterway in the engine cylinder has been repaired) has impurities such as scale and rust, which affects the fluidity of water; Second, the poor pumping ability of the water pump leads to poor circulation of coolant; Third, lack of coolant or engine boiling water; Fourth, the fan is not easy to use or the running speed is not enough, which leads to less cooling air; 5. The radiator is too dirty, causing the wind from the fan to be insufficient to cool the coolant in the water tank; Six, water temperature sensor circuit failure or ECU failure; Seven, the cylinder gasket was washed away, resulting in water and oil mixed together. According to your text introduction, it is very likely that this fault point. You can go to a regular enterprise to check whether there is milky white foam in the engine oil and whether there is engine oil in the coolant. You can also use professional instruments to check whether there are bubbles in the water tank to judge whether the automobile cylinder mattress has been washed away. Eight, the ignition time is not equal. Will cause the water temperature to be too high.
