As I pulled out the back seat of my Westy I discovered a long-hidden
coolant leak. The slow leak is coming from what I believe to be the
control valve for the rear heater. I didn't even know there was one.
Can't find a picture of this part in my Bentley, so I'm appealing to the
list to confirm my suspicions. The leak seems to be coming from behind
the control lever (aluminum) itself. Is this something that is fixable
with a new seal, or is this part notorious for leaking and needs to be
replaced in total?
