In this video, you will see how to bleed the thermostat of the cooling liquid of a Renault F9Q DCi engine: the footage shows the return circuit with all its components, including the temperature sensor and the bleed screw, which allows you to drain the system.

Naturally, this operation should not be performed with a hot engine, as you risk burns.

Check for any whitish traces indicating a water leak; micro-leaks are very common in this type of model. The electrical connector can be easily removed by pulling the plastic clip, revealing traces of the liquid passage inside.
