Where to pour antifreeze in Renault megane engine?

In a Renault Megane, you should pour antifreeze into the coolant reservoir, which is typically located near the front of the engine bay. Look for a translucent tank with a cap labeled with a coolant symbol. Make sure to use the correct type of antifreeze specified in your owner's manual and check the fluid level to ensure it's within the recommended range. Always allow the engine to cool before opening the reservoir to avoid burns.
