too cool temps in the winter

Cool running means that the engine isnt heating the coolant.
IE the thermostat is stuck OPEN not closed ( if it stuck closed,
engine would overheat)....
Blocking the radiator means that you will not be able to further cool
the coolant that the engine is not being given the opportunity to
heat (stock thermostat is supposed to stay closed until the coolant
in the block gets to 87 C), therefore what little heat is being
transferred to the coolant from the engine can now be retained until
it gets to the heater core, where a blower pushes air over the core
and removes heat from the coolant...
