Conventional thermostatically-controlled valves (outlet water temperature control type) open against the flow of coolant. In the M7040SU Tractor, the pressure (steam pressure + water pump’s discharge pressure) affects the open/close performance of such valve. In other words, the valve may be delayed in opening at a preset opening temperature opening suddenly, above the preset temperature. This is called the overshoot phenomenon.
The overshoot problem invites the undershoot phenomenon too. Too much water cooled by the radiator flows through the water passage, which suddenly closes the valve below the thermostat’s preset valve closing temperature.
A repeated cycle of such overshoot and undershoot phenomena is called the water temperature hunting.
This hunting problem may adversely affect the cooling system parts, and also the engine and its related components.
To cope with this trouble, the V3307 engine is equipped with the flow control thermostat. The valve has a notch to control the coolant flowrate smoothly in small steps.
