Dumb question.  I have a Pacific Oil Cooler mounted on the nose on my M20F.  It looks reversible.  The fins on the inside, facing the engine, are mostly unbent.  The fins on the outside, facing the impact air, are fairly bent and beat up.  Looks like it has mounting holes on both sides?  Is the oil cooler reversible?  Can it be turned around?  Does the direction of oil flow through the cooler matter?

Direction doesn’t matter, but putting the restriction on the exit restricts airflow just as well as it being on the inlet so you wouldn’t accomplish anything, just carefully straighten them by whatever means, I think the HVAC combs work well and don’t crease the fins, if you use tweezers etc be careful to not put a crease because that will eventually turn into a crack, not the end of the world but you can prevent it just by being careful.

When I owned an F, I would go out to the plane every few years and sit on a stool in front of the oil cooler with some 2C tweezers and spend about 1/2 hour straightening out the fins.

I thought perhaps 2C was a brand.  Who knew?

Uh, where’s the 2C?

I wondered about that.  I found some that are 2C but this was the best picture.
