We continue our specialization in the field of engine cooling, and in particular the control of coolant temperature. We are introducing our range of thermostat flanges (also known as temperature management modules).

A thermostat in a car is a part of the engine cooling system that keeps the engine at an optimal temperature, ensuring efficient performance and preventing damage due to overheating or running too cold. The thermostat controls the flow of coolant between the engine and the radiator and regulates it based on the temperature of the engine.

How it works

When the engine is cold (for example, at start-up), the thermostat is closed and prevents coolant from flowing to the radiator. This helps the engine to reach operating temperature quickly. Once the engine reaches operating temperature, the thermostat opens, allowing coolant to circulate in the radiator, where it is cooled, preventing the engine from overheating. In effect, it is a valve that opens and closes automatically to keep the engine at the right temperature.

In many cases, the thermostat valve is enclosed in a housing (also called a thermostat flange) that holds it in place in the engine cooling system. It mainly serves to provide a connection point between the thermostat and the engine, serving – besides as housing for the thermostat itself – as connection interface for the hoses that carry coolant to the radiator, engine, or heater.
