When will replacing a thermostat improve cooling?



more reason to have a working one in place!

the uneven temp rise through out the cooling system,
the coolant will seek the easiest path to the flow.
Without the restriction of the Stat the coolant will not flow as completely thru all parts of the cooling system with an equal force.
This will creat "Pockets" of lower temp coolant that will cause problems.

No, I'm not saying that at all. What I am saying is that if the watter in your bucket was flowing very quickly, it would cool the steel at the same rate (or even quicker) than if it was not moving at all.

Same think would work in reverse... if the water was hot and the steel was cold.
