Oil Cooler Positioning ! Lets Settle This Once And Fo All

[robots]

There seems to be a lot of misleading info here and on the net.

Which is the right way to mount the oil cooler ? With lines going from the top or the bottom ?

Some say that when you mount the oil cooler upside down you will have hard time bleeding the system and there would be some air trapped in the oil coller ? Is this correct ?

And full race seem to have mount them upside down.

Lets discuss !

My lines are at the bottom. Never had a problem, and on teardown of engine bearing shells were in good nick(70,000k and 400hp + atw) with oil cooler installed.

I've mounted mine on its side. Oil into the top fitting and out the bottom.

It also makes for easier draining of the cooler on oil changes

Same setup although I'm not 100% on the IN and OUT positions (i.e. top or bottom) don't think it matters considering the oil pressure, not like gravity will stop it.

I think URAS mentioned that bottom is FAIL somewhere? And lots of confusing info. Right now I run IN OUT at the bottom. Don't have a problem also. But want to make sure.

my in and out are on the bottom.

No issue.

as stan said, with 4 bar plus oil pressure gravity doesn't stand a chance.

But! i'd have thought more people would be concerned with maintaining oil in the lines after the car is stopped to minimise the time it takes to build oil pressure on start up.
