Have a Clio 2 1.4l year of construction 2001 if it is running in the stand the water level at max even if it is running longer if I then let it drive a bit we are 10km then the water level is bagged when it is standing again the water level rises but again does not rise to max but it rises again easily. The days timing belts were replaced with water pump. Could be the water pump leaking I can see so nothing you can see much but what do you think that can be a problem e. MFG
