[TR] Interesting cooling system web page

> The water must stay in the radiator long enough to cool. 

And as the water cools in the radiator (and warms in the block) the 
rate of heat transfer from (or to) the water slows down.

> If it moves too fast it will return to the engine too hot to help.

And if it stays in the radiator (or engine) too long it will become 
too cool (or too warm) to help.

Heat transfer is directly related to thermal gradient.  If the 
average temp of the radiator is lower then there must necessarily be 
less heat being transferred per unit time.  The ultimate case, of 
course, is when the belt breaks and the water speed drops to zero.  
The radiator will cool and the block warm...
