① The engine temperature is too high ("boiling" exceeds the critical temperature line of the engine); ② If the temperature exceeds 100, continue driving until the engine shuts down by itself (the reason for the high temperature has been mentioned earlier);

(3) When the temperature is too high and the engine goes out by itself, open the hood and let it cool naturally (don't open the expansion valve cover to burn at this time), and then add water. Generally speaking, the cylinder gasket has been washed away and needs to be replaced.

2. Causes of cylinder head deformation:

When the temperature is too high, keep driving until the engine shuts down automatically, and immediately open the expansion valve (users use towels or other things to prevent steaming.

Add cooling water immediately, and the cylinder head will be deformed and scrapped.
