http://www.peachparts.com/shopforum/diesel-discussion/281695-w124-climate-control-vacuum-valve-repair-diy-4.html, to my favorites in case I ever needed it for future reference. Well, I needed it today, but the pics are dead. Does anyone have a diagram of how the coolant flows through the heater core in a ‘95 E300? Thanks!
