Monovalve is under the leaf cage on the passenger side right behind the fire wall. Unless you live somewhere where the temperature drops to the negatives, I would remove the aux water pump and put in a manual ball valve in its place. I close the valve during summer to stop coolant flow and I open it in the winter.
