However, I now believe that is overkill for the coolant system, it is certainly expensive as you have indicated (was a bit cheaper back then) and it is also considerably heavier than say good quality radiator hose. In short, I believe that good quality radiator hose replaced ever two years will probably work just fine. But, I must say I have had no problems with busted hose or leaks. Also I think unscrewing an AN fitting is less detrimental to the life of the hose than prying off radiator hose off a fitting. As far as space, I don't have the measurement handy, but with my radiator placements the distance on the bottom was not critical. I would say approx 2 - 2 1/2" should be the min allowed. You can find less expensive fitting around by searching the internet. > Along the lines of Ed Anderson's.
