Thermostats regulate the temperature of the coolant in the cooling system of the vehicle engine under all conditions. This is of particular importance for the durability of the engine, the fuel consumption of the vehicle and the exhaust gas development.
A thermostat, the wax pellet of which registers the temperature of the coolant flowing around it, provides for the allocation of coolant flow, either through the coolant cooler or past it via a short-circuit line.
This means that at very low coolant temperatures, cooling is largely avoided and at high temperatures maximum cooling is provided.
In the closed position, a by-pass valve enables the required minimum flow rate of coolant, to prevent damaging over-pressure in the engine.
High flow rates are achieved by double-thermostats, which have two different opening temperatures in order to ensure a uniform engine temperature.
To ensure resistance to the corrosive substances in the coolant, individual components affected are made of corrosion-resistant materials, such as stainless steel or brass.
Some thermostats have ventilation holes with a valve, which simplifies bleeding of the cooling circuit when replacing components.
