YES! The 93 heater valve is different 200 1993

I recently inquired on the board if anyone had any experience with a leaking heater valve on a 93 240. Many wrote back pointing out it's location above the throttle pedal. This is how the Bentley manual depicts it also. But the one on my 93 is quite different. There is obviously a leak here (seen in photo).
FCP does not mention this different valve either.
I'm not even sure how to remove the valve, as the other hose, which I assume goes to the heater core, is on the other sider of the valve, buried under the fan case.
Anyway, here it is, different from what we all think it should be.

Here is a shot of the heater valve on my 93 245 Classic.

This is taken from about the position of the driver's right foot, looking towards the right side of the car. You can see the vacuum resevoir on the right side of the photo.

    That picture of the heater valve location is identical to the ones I've changed on our 89 244, 90 244, and 92 245. A real PITA to swap out but it can be done with cut knuckles and two hours time.

      So, I guess they changed the valve awhile ago from what I remember on my 81 and 84 240's.
      Any hints on how to proceed?
      I was thinking clamping off the intake hose, the one in the picture, disconnecting it, then pulling the assy. out the right side into the passenger footwell.
      The hassle may be disconnecting the cable to the adjustment lever?
      The bracket is loose at this point as I have removed the nasty pointed clips which held it to the heater box.

        When I replaced the valve X3, I drained the coolant system first by utilizing the drain plug on the passenger side of the block. Please note, coolant will remain in the hoses and core, so have a bowl handy to catch the coolant when you disconnect the valve hose on the driver side.

        Once the driver side hose is disconnected, undo or break the mounting clamp that hold the valve in place. Pull the valve assembly towards the driver side foot well and unhook the S-bend control rod from the valve arm... be patient, you don't want a kink in the rod.

        Once the control rod is unhooked, pull the valve further into the driver side foot well and unhook/unclamp the other hose.

        Installation is the reverse of removal EXCEPT it might be easier to connect the control rod before hooking up the passenger side hose.

        Hope that helps... oh yeah, make sure you don't ingest ANY coolant as its very bad for your kidneys and is easy to do with your head on the floor!
