Wholesale Forklift Parts Suppliers Heli Lift Truck Thermostat for Xinchai 490b Engine

The thermostat, as an important valve that controls the flow path of coolant, is installed at the connection between the lower hose and the engine. A thermostat usually consists of a spring, a hose, a temperature-sensing component, a thermostat valve, a valve seat, a push rod, and an upper and lower support. When the engine coolant temperature reaches the operating range, the thermostat opens, the bypass is closed, and the large circulation mode is turned on, forcing the engine coolant to flow into the radiator for cooling.

If the thermostat is damaged or malfunctions, it will seriously affect the normal operation of the engine. Therefore, maintaining the normal working condition of the thermostat is crucial to ensure the operation of the forklift engine.
