oil cooler, fittings up or down?

And, I still don't understand the logic. How will the oil cooler get dirty and not the rest of the parts in the motor? Is the oil cooler a filter? Will it get clogged up? I'd think the bearings in the motor will spin before a row in a cooler gets clogged. I'm pretty sure most oil adapter plates direct the oil through the oil filter first, before sending into the cooler and thus, filtered oil is always entering. If the cooler is clean from the get go (brand new) then you will never ever have a problem. If for whatever reason you feel your cooler is dirty, you are supposed to replace it. If your oil is in fact getting that dirty, you're either not changing it fast enough, or you have other issues with contamination.

I'm not trying to pick a fight with you, please do not misunderstand me. I'd rather everyone really understand and put this to rest.
