Citroen Sega thermostat location

On the right side of the cylinder head (gearbox side), there is an aluminum water outlet chamber. At the front end of the water outlet chamber, near the water tank, there is a black plastic water pipe connector, and then there is a rubber water pipe connected to the water tank. The thermostat is in the black plastic connector. When I changed it, I changed it to a black head, which is a whole with the thermostat, that is, the thermostat.

The thermostat is an instrument, as long as the water temperature does not exceed 90. Thermostat is a valve that controls the flow path of coolant. It is an automatic temperature regulating device, which usually includes a temperature sensing element, which opens and closes the flow of air, gas or liquid through thermal expansion or contraction.
