The coolant temperature sensor in a Renault Megane Scenic is located on the right hand side of the engine as you are looking at it. It is located just above the TDC sensor.
To replace the TDC (Top Dead Center) sensor on a Renault Megane, first disconnect the battery to ensure safety. Locate the TDC sensor, typically found near the crankshaft pulley or on the engine block. Remove any necessary components for access, then disconnect the electrical connector and unscrew the sensor. Install the new sensor by reversing the steps, ensuring it's properly secured, and reconnect the battery.

You have to remove the battery to take it out and see it better, one the battery is out you will see two small bolts that hold the sensor in pace over the crankshaft. Peter
