BigSmokey said:I would think a double pass forces the water to contact more of the exposed radiator surface by creating a tighter channel for the water to travel.
BigSmokey said:A single pass could have dead spots.
Altima said:does single series split up and run in parallel though? this would still be effective, and lots less flow restriction.

Why do you think a dual pass heatercore will cool the water more effectively? I don't know of any reason why this would be true.
Raider84 said:because it travels twice the length as the single pass, therefore enabling the water to have more time to be cooled by the air running over the fins.

It would seem that a "single pass" would mean single channel and "double pass" would indicate a U shape. This assumption could be most non-scientific though, since often things are named for how they appear and not how they work. For instance, a double pass could be a W patern and a single pass could be an S.
