What's Wrong with a Faulty Thermostat?

[ColinFitz]

The common causes of thermostat failure include: 1. The valve opening and fully opening temperature is too high, or it may not open at all: This prevents the coolant from effectively circulating in a large loop, causing the engine to overheat. The solution is to replace the valve. 2. The thermostat does not close tightly: This leads to slow engine warming, resulting in the engine being too cold. The solution is to replace the thermostat. Information about the thermostat is as follows: 1. Most thermostat valves are made of aluminum alloy. If unclean water is added for a long time, the aluminum alloy can corrode and rust. When the engine water temperature rises to 80°C, the main valve of the thermostat should open normally to start the large circulation. 2. The thermostat is part of the cooling system. This component is used to control the coolant's circulation between large and small loops. Water-cooled engines rely on the continuous circulation of coolant within the engine for heat dissipation.
