RE: OIL/WATER COOLER

["Avi Meron" <avi@cosmoslink.net>]

As a general rule (very very general) it is much more efficient to use
coolant to warm up the oil and to cool off the oil, not air.....air is
actually a less efficient way to cool of the oil (by a long shot), you need
a much bigger surface (note the size of an air to oil cooler) as you would
need if you were to accomplish the same temp. drop via coolant cooling.

Yes, it seems a bit weird to move the heat into the coolant, then it
still has to be moved into the air anyway.  And when the oil is getting
*hot* the coolant is working hard as well.  And with oil to air the
plumbing is simpler.
