Coolant AN Fittings (M20)

[02tradition]

I tried the search function but of course the term "AN" is too short. Maybe someone can point me in the right direction if I have missed something (ie. previous posts, links, etc.)

I have a 2002 with an M20 swap I am putting together. All my fuel, oil, diff cooler lines are AN so it would be nice to get the cooling system to match. (and now would be the time for me to accomplish this)

Basically looking for info on the AN sizes for the different hoses and possibly the source you obtained the fittings from. Also any pics of a setup like this would be helpful.

TIA

The largest AN fitting size I've ever actually seen is -16AN, which is 1" ID, which is smaller than the standard coolant hoses (they're closer to 1.5" ID). I've never heard of using AN fittings for coolant lines. -32AN is apparently a spec, and its ID is 1 3/4". That's the biggest available. -28AN or -24AN might work, if you can actually find any.
