The task of the engine cooling system is to remove the excess heat generated during the combustion process and transfer it to the individual parts of the engine and into the engine oil.

Engine cooling is, therefore, a critical aspect of maintaining optimal engine performance and extending its lifespan. It protects the engine and components from overheating and ensures a stable engine operating temperature.

The temperature of the coolant is very important for the correct and efficient operation of the engine. Every engine has a certain ideal working temperature that it needs to reach for its optimal operation.

For proper engine operation, the ideal coolant temperature is between 80°C to 90°C (176 to 194 degrees Fahrenheit), depending on the type and construction of the engine.

A thermostat is a device that controls the flow of coolant liquid in the engine's cooling circuit. Every engine has a certain ideal working temperature that it needs to reach for its optimal operation.

If the engine does not work at its ideal working temperature - it is not optimally warmed up - it leads to higher fuel consumption, worse operation, higher noise, but also greater wear of all engine parts.
