Product Description: The thermostat is a valve to control the flow path of coolant. It is an automatic temperature regulating device, usually containing temperature sensing components, which can turn on and off the flow of air, gas or liquid by expanding or contracting. Thermostat is to automatically adjust the amount of water entering the radiator according to the temperature of cooling water, and change the circulation range of water, so as to adjust the cooling capacity of the cooling system and ensure that the engine works in the appropriate temperature range. The thermostat must maintain a good technical condition, otherwise it will seriously affect the normal operation of the engine. If the main valve of the thermostat is opened too late, the engine will be overheated; if the main valve is opened too early, the preheating time of the engine will be prolonged and the temperature of the engine will be too low.
In a word, the function of the thermostat is to keep the engine from undercooling. For example, after the engine is working properly, the temperature of the engine may be too low if there is no thermostat when it starts in winter. At this time, the engine needs to temporarily stop the water non-circulation to ensure that the engine temperature is not too low.
