Which Way Does It Go ?
 
I recently installed a Mesa remote oil cooler on our 914 by installing a oil filter sandwich adapter and running hoses to the cooler. My question is this; does it really matter which hose I connect from the sandwich adapter to which port of the oil cooler? The sandwich adapter has one arrow scribed on one port indicating out. The oil cooler also has one port scribed out. Neither item came with any directions, sooo - what is the purpose? One way or the other, the oils going thru the cooler. Either before the oil filter or after...Right?
Thanx,
Gary:o

In to the lower port on the cooler, out of the upper port. Otherwise, the oil will go straight from the inlet to the outlet on the cooler and not go through the cooling fins!!

Or rather, much of it will tend to do that...

I don't understand...There is no lower or upper port. I mounted the cooler flat, under the rear trunk. I believe there are only two possibilities. 1.) the oil gets filtered & then goes thru the cooler & back to the engine. Or 2.) the oil goes thru the cooler and then gets filtered prior to going back to the engine. Right???

Oh... Sorry, I mixed up which "inlet" and "outlet" you were talking about!

Generally, you want to filter the air before you cool it. The filter helps de-aerate the oil (e.g., pops the bubbles in the oil foam) and liquid oil cools better than oil foam. Also, this gives your filter a chance to trap junk before it gets into the cooler.

Then again, the filter bypasses some of the oil most of the time anyway, so that's not any kind of guarantee...

But, as I said, usually you cool filtered oil.

Way cool info. Thanks Dave. Well then , here's my next question; which port of the sandwich adapter goes to the filter first?
