First of all, excessive pressure is abnormal and dangerous.
It's possible. Please check whether the coolant flows through the glass tube of the cooling system. If it doesn't flow, it means that there is air in the pump and the liquid doesn't twitch, resulting in great pressure. 2 Pressure According to the temperature of the cooling system, insert a thermometer to see the actual temperature. 3 Check whether the pressure gauge is normal. 4 Some bad coolant will affect the cooling system, such as excessive foam. . There are many factors. Let's stop here. I hope I can help you.
