>Help. In front of me I have a heater valve for a E12 (5 Series thru '81) or I just did this, and it ain't pretty. Well, if you _don't_ have A/C, then it's probably pretty easy -- just removed the entire center console, w/the heater core, and should should then be able to pull the whole unit from the firewall, after you disconnect the two heater hoses in the engine compartment. But if you do have A/C, and you're not inclined to disconnect the hoses at the evaporator in the center section, then it gets real ugly. Ultimately, I had to take a torch to a Craftsman wrench and bend it ("L"-shaped) so that I could access the two nuts that are towards the center of the car. The two others, I was able to do upsidedown with my head under the steering column. Plus, the "accordian" air tube gets in the way while you're doing the upper nuts. I replaced the O-rings, and lubed them w/Vaseline, but I don't know how long they will last -- the recess in the valve is not designed correctly for those O-rings. I discovered that this is my '77 530i's _third_ valve -- it was first replaced in '85- or '86. Fun Fun Fun ...
