How to replace the thermostat in the Renault Megane?

Model: Renault Megane Megane III, Megane 3 - Years 2008-2015
Part: Thermostat

In this tutorial we can see how to replace the thermostat in the Renault Megane, a simple operation but one that requires good manual skills. First of all, make sure that the engine is completely cold, then go underneath it, remove the protective panel and, by disconnecting the indicated tube, drain all the coolant contained in the system. Open the hood, disconnect the power terminals of the battery starting from the negative and remove it. At this point, all that remains is to remove the thermostat, position the replacement, reassemble everything and add the necessary amount of coolant to fill the system.
