The material of the thermostat harness is usually made of high-temperature and corrosion-resistant materials, such as PPS (polyphenylene sulfide). PPS material has the characteristics of high temperature resistance, corrosion resistance, acid and alkali resistance, can maintain good mechanical properties in engine antifreeze at 130°C, and has excellent integrated forming performance, can effectively prevent the risk of leakage, improve the sealing and reliability
Function
1. controls coolant circulation : The thermostat controls the temperature of the engine by regulating the flow of coolant. In the low temperature state, the thermostat is closed, and the coolant only circulates inside the engine, which is called a small cycle. When the temperature rises, the thermostat opens, and the coolant enters the water tank for large circulation, thus regulating the temperature of the engine
2. prevent the engine from overheating or overheating : when starting at low temperature, the thermostat suspends the water circulation to prevent the engine from overheating; At high temperatures, the thermostat regulates the amount of water flowing into the radiator to prevent the engine from overheating 4.
