I work in a medical device industry and understand that inspections are only ~80% effective. Add to that the possiblity of a defect being below the surface and not visible during an inspection, and it just does not make $ sense to remove the radiator (disconnect the hoses), and put it back in with old hoses, IMHO. Hindsight is surely 20/20, but I bet your wife will insist from now on that these hoses are changed regularly.
It only took one radiator hose incident for me to make this part of routine maintenance. Having said that, I just remembered that our "new" Outback is due for a hose replacement. I will probably flush out the cooling system and replace the hoses very soon. Don't want to have the wife stuck on the road and have to deal with the complaining, you know.
