Since you haven't explained the situation in detail, I can only help you analyze some reasons for the high water temperature:
The high water temperature is mainly related to poor heat dissipation, which is caused by many reasons, such as: the cooling system (water tank and pipeline, the waterway of 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; 6. Incorrect ignition time will lead to high water temperature.
High water temperature is not difficult to repair, the key is to be careful.
High water temperature is very harmful to cars, which can directly lead to engine cylinder pulling when it is serious, so it should not be underestimated. I also hope my answer can help you.
