What size AN hose for radiator?
I'm using a true 16AN top radiator hose on my car, and would like to convert the bottom as well.
Not sure what size i need to use...16 AN seems a little small, so maybe a 20 (but then I can't use black fittings/nylon braided hose that I have on top). Anyone have experience/done this?

I don't know your application but normally the lower hose is slightly larger than the top hose. I'm sure GM engineered it that way on purpose. 20an might be to small.

I spoke to Meziere and my waterpump (chevy small block) inlet fitting is basically designed for 20AN, so I should be ok using a 20 AN on the bottom.
