Rad Reserovoir (1 Viewer)

Is it necessary fix the Reservoir in the same level with Radiator upper tank.

I observe some coolant losses but there are no visible leaks. My reservior is placed a little below the Rad upper tank & presume coolant overflows while running.

as heat builds up in the radiator to operating temperature, the water expands and fills the reservior by lifting the big foot valve under the cap, once the water cools again it slowly sneeks back through the little foot valve in the centre of the big one. it uses pressure not gravity to fill so it shouldnt matter about the hight. if you cant find a leek, (look on the drivers floor and rear floor aswell) you could pressure checked your cap.
