What is a tractor thermostat?

The coolant thermostat is one of the most important components of the cooling system and is responsible for controls and regulates the temperature of the coolant. The thermostat is a device that works under the influence of elevated temperature, and its correct operation allows you to maintain the right temperature needed for the most effective operation of the engine. When the temperature of the coolant rises to a certain level, the thermostat "opens" under the influence of heat, passing the coolant to the second circuit (radiator), which allows the fluid to be cooled effectively, and the engine to continue.

The first signs of a malfunction of the thermostat?

Overheating of the engine or very long heating of the engine to the appropriate operating temperature are the most visible symptoms of a thermostat failure. Failure of the thermostat in the closed position causes the engine to overheat and is very dangerous for the engine, so when the fluid temperature indicator light comes on, stop work and turn off the engine as soon as possible. A less dangerous situation is when the thermostat fails in the open position because the water circulating in a large circuit affects the engine overheating and it is a failure less dangerous for the engine, but in the long run it also has a negative effect and is harmful to the engine.
