I am thinking of replacing the coolant in my 1996 E320. Having a Miti Vac, which I also use for oil change, I am wondering if it is possible to vacate the coolant with it, it would spare me the hassle of lying on the back to drain the coolant thru the radiator plug with the fear to break the plug as happened to some people.

Is putting the vac tube thru the hole after removing the thermostat feasible, or thru the radiator hose?
