Thermostat / Ø 44 mm / 82°C / Yanmar 3TNE68 / 119260-49801

Thermostat for tractor with flange diameter 44 mm , total height 39 mm , opening temperature 82°C for Yanmar tractors with Yanmar 3TNE68 engines and others.

The coolant thermostat is one of the most important components of the cooling system, responsible for monitoring and regulating the coolant temperature . A thermostat is a device that responds to elevated temperatures, and its proper operation allows for maintaining the correct temperature needed for the engine to operate at its most efficient level. When the coolant temperature rises to a certain level, the thermostat "opens" due to heat, allowing the coolant to flow into a secondary circuit (the radiator), effectively cooling the coolant and, consequently, the engine.

Engine overheating or a very long warm-up time to the proper operating temperature are the most visible symptoms of thermostat failure. A thermostat failure in the closed position causes engine overheating and is very dangerous to the engine. Therefore, when the coolant temperature warning light comes on, you should stop work as soon as possible and turn the engine off. A less serious situation occurs when the thermostat fails in the open position , as the water circulating in the large circuit prevents the engine from reaching its operating temperature . This failure is less dangerous for the engine, but in the long run, it also has negative effects and is harmful to the engine.
