[TR] Water pumps.

I just think of it like this - flow through the radiator should be the same as flaw through the engine.too fast to offload the heat would equal too fast to take it on? There are likely cases where the thermal transfer into the coolant exceeds the ability of the system to offload the heat, thus the temperature of the coolant will rise.The good news though is it will eventually reach stasis.  As the coolant approaches the temperature of the item being cooled, the delta T will fall and the heat transfer in will diminish while at the same time the delta T between the radiator and the ambient environment will rise and more heat will be transferred away.  Although in automotive applications, the coolant will likely boil or the system will otherwise fail before reaching that point. In short - good, clean radiator, adequate quality coolant under proper pressure, and adequate airflow are likely more important than variables in coolant flow - as long as it is flowing!
