I am having issues with the cooling system on my k20 turbo integra.. I got my radiator with a 12" spal fan.. but my issue is the coolant upper coolant filler on the k20.. i was thinking about taking it off and welding on a filler neck like the k tuned one.. is it that simple.. so i could put the correct amount of fluid and not having air in it.. what are u guys doing about this..
