Bob,

just ot make sure, whatever position you mount the cooler, do it so that any
gas (trapped air, oil vapor, etc.) can be pushed out in FLOW-Direction, not
against it. Also make sure that the outlet is at the highest spot, even if
you have to mount the cooler a little crocked (un-estetic, but works!).
I remember some 20 years back BMW started to offer oil-coolers on their
bikes. Lots of them had trouble with oil-temp after oil-changes:
Oil would drain out of the cooler - oil-pump starts to load the cooler and
in the process trapps a good amount of air - inlet and outlet where facing
down for more estetic oil line routing (or cheaper, shorter lines :)).
Easiest fix was to mount the cooler up-side down, get 180º fittings and
mount the cooler lower so the orignal lines would fit - no more trapped air
as it was pushed out the outlet as the cooler filled up.
I believe the coolers were single pass.

Thomas J.
