GQ patrol hoses

Hi all, great forum.
Just wanted to impart so info.
Just replaced all the small water hoses on my 1990 GQ patrol(4.2 petrol auto). Have been losing 1 or 2 cup fulls of water every trip. Noted that the hose under the carby had some evidence of leaks so decided to bite the bullet and replace them all.
I had been putting it off because I had visions of me having to remove the inlet manifold to get at the connections etc.
Finally decied I could stall no longer and removed carby and found that by removing crankcase breather fitting Icould get at most of the connections.Well after a lot of struggling underneath the carby (working by feel) I managed to remove the old hoses and check the connections for corrosion. All seemed ok so I replaced the hoses (all 3) and installed new hose clamps(the jubilee strap type, I dont like the double loop originals, they tend to cut the hoses).
All went back together. Refilled radiator with demin water and looks ok. I wiil reflush and refill with demin water and inhibitor at next opportunity(tonight?)
Note: you dont have to remove the inlet manifold to replace these hoses, as long as the steel fittings are ok( not corroded)
Use only distilled or demin water and flush a couple of times if changing from tap water etc. I use 4 ltrs Castrol anti-boil,antifreeze with inhibitor to give 50% concentration. This was recommended to me by a friend who knows his chemistry and says this will help prevent corrosion in the mixed metal cooling system.
