Where is the thermostat located?

[VeraRose]

The thermostat is located inside the pipe at the interface between the lower radiator hose and the engine. You can see the thermostat by removing the pipe. The refined paraffin inside the thermostat's temperature-sensing body is in a solid state, and the thermostat valve, under the action of the spring, closes the passage between the engine and the radiator. The coolant returns to the engine via the water pump, creating a small circulation within the engine. The thermostat automatically adjusts the amount of water entering the radiator based on the temperature of the coolant, changing the circulation range to regulate the cooling system's heat dissipation capacity and ensure the engine operates within an appropriate temperature range. The thermostat must maintain good technical condition; otherwise, it will severely affect the normal operation of the engine.
