As best I can tell, the owner indicated that the hot coolant comes into a baffle in the top tank, flows down thru a set of tubes (in this case staggered vs the original inline), then back up thru the next set of tubes into the next baffle and then back down, etc. until it exits 'icy cold' (ha).
I didn't see the inside of the tank so I can't confirm the configuration, and am not familiar with Pantera radiator.
Hopefully the staggered tubes and louvered pins will make this goose run a little cooler.
