Rusty...Thank you for getting me the OEM monovalve. I installed it a couple of weeks ago, but have not driven the car due to the snow and ice. I finally had the chance to test it yesterday (Maine to NYC) and it performed flawlessly. At cruise, the valve modulated as advertised putting out warm (not hot) in the footwell, and when necessary cool air from the dash vents. It really is nice to have a working ACC system!!!
Unfortunately, The MTC aux pump looks like it is starting to leak again. Not as bad as before, but enough that I can see coolant in the engine compartment under the pump. I'll try and get the screwdriver on it again to re-tighten. BTW, this is not a complaint. I am merely posting as a lessons learned for anybody else with a new MTC aux pump.
