Coolant air bleed valves

Good morning all,

Does anyone know where these are in the megane 250? I can only find the one behind the engine and turbo

Many thanks

 

Does anyone know? Can only get 2 litres in the bloody thing as its not draining properly

 

Well the second bleed valve is on the thermostat incase anyone is searching in the future Left of the battery casing

Also done my gearbox oil as the car has hit 50K now and that's defiently worth doing. Quite as easy job but you need to get the battery out
