Galling can be a problem, but doesn't have to be. Aluminum AN fittings are hard anodized, and oil coolers usually are not. As long as you use a good thread sealing/lubricating compound, & don't over-tighten (most important), you won't gall the threads. Bare aluminum against bare aluminum is much more of a problem, but the anodized fitting can be successfully used with aluminum that is not. The admonition to use steel fittings on carburetors, oil pressure lines, etc. is definitely rooted, at least partially, in the fact that there is a lot of vibration on & around an engine, and steel is much stronger, heat resistant, & less prone to fatigue and cracking. Brass also work hardens & can be prone to cracking. Anodized aluminum is fine as far as compatibility with fuel is concerned.

If you try, it s trips the threads on the oil cooler. I lost a $200 oil cooler trying to re t ighten the fittings.
