The mono-valve controls the flow of hot coolant to the heat exchanger. The fan blows outside air across the heat exchanger and into the cabin.
Testing the heat exchanger is same as testing the radiator: pressurize the entire system, and if the pressure drops, you have a leak. Test YOUR theory by taking a sample of all the fluids from your car and heating them up on your stove. If any of them are responsible for your smell, then you'll know which system is leaking.
