Thermostat

Thermostat Seal is used for thermostat. Thermostat automatically adjusts the amount of water entering the radiator according to the temperature of the cooling water, and changes the circulation range of the water to adjust the heat dissipation capacity of the cooling system and ensure that the engine works within a suitable temperature range. The thermostat must be kept in 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, it will cause the engine to overheat; if the main valve is opened too early, the engine warm-up time will be prolonged and the engine temperature will be too low. All in all, the role of the thermostat is to keep the engine from getting too cold. For example, after the engine is running normally, the temperature of the engine may be too low if there is no thermostat when driving 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.

Thermostat fault diagnosis method:

Under normal circumstances, when the engine is cold and started, the working temperature is very low. In order to make the temperature rise quickly, the coolant is controlled by the thermostat to be pumped into the water distribution pipe, and the coolant does not flow through the radiator. , this time is a small cycle, when the temperature of the coolant reaches 87 degrees, the thermostat valve opens, the coolant begins to flow through the radiator, and the cooling system enters a large cycle.
