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...

Make sense?
