Radiators are designed for the "worst case scenario". Think 124 degrees stuck in traffic in Phoenix AZ in July.
Now think about -40 degrees (C or F=same temp), you have 5 times the radiator you need to keep the engine cool. In fact it's almost impossible to keep the engine at operating temperature, so like the big rig drivers, block the airflow over the radiator to retain heat energy, until the coolant exiting the radiator is the same temperature as it was in July (probably impossible when it is that cold).
Adding any restriction to coolant flow does not address the grossly excess radiator capacity when ambient temperature is 164 degrees colder (124 vs -40).
