Howdy, the monovalve on my 84 300D lets coolant through all the time, never completely shuts it off, raises the air temp 10 - 15 degrees at its coldest setting when it should be shut off. The valve was replaced a couple years ago by a Mercedes shop. Seems too soon for it to have gone bad, but who knows.... I see that those valves have rubber washers or o-rings or whatever rubber parts on them to create the seal to stop the flow of coolant, and was wondering if there is a seat inside the monovalve housing that could be pitted or corroded that could be causing the rubber parts of the valve to not seal properly. I have never taken one of these apart. Any advice is appreciated. I'd like to fix this once and be done with it for a while.
Thanks,
Jim
