What size AN Fittings I should use for the Upper and Lower Radiator Hose?

 

99.999% of people with braided radiator lines are just dress up kits.. the radiators aren't threaded or anything to accept the lines in normal civics and integras

 

Uhh yeah. Unless you have an aftermarket radiator that comes with AN fittings, you're going the have to weld AN fittings on, then weld fittings for the block side as well. It ain't worth it.

 

yeah your over it the hose is like 30 bucks a foot, the fittings ? a -18? 90 degree, like 40 a piece, and welding 2 more fittings to the radiator 50. though that would defenitly get the thumbs up from anyone but still useless and a pain unless it's all show
