I think I have bad drain valve on the radiator on the MY11 E-350BT. I'm getting started on replacing an EGR valve, etc. so I'm draining the coolant. I located the drain valve, lower right of radiator; catch pan is ready, turn the valve (horizontal initially) ccw to open (vertical now), and nothing. Uh? I do have the coolant reservoir cap off. I'm scratching my head here! Suggestions?

I just did this a few weeks ago, you have to turn it more than 90 degrees to open it.
I thought the same thing when did it.

Thanks sghokie, I'll keep on twisting ccw; I fear these plastic parts. Last thing I want to do is bust that valve.

I had to do the thermostat and was very very paranoid about stripping out the holes in aluminum.

Call me paranoid, but it takes a full turn of the drain valve to open, not just a quarter. That yellow line marking the closed position of the valve made me think it's a quarter turn, and it didn't turn so easy.

Well, now on to the real work at hand....going to clean the ERG actuator, clean the EGR cooler, replace the turbo (bearing seized up), and while I'm that far into it, replacing the oil cooler seals too. . . WTF, only 77K miles, but I'm the second owner so.....who knows!
