Radiator hose replacement

[not2old]

In 21 years and 415,000 KM I've replaced my lower ones(2) twice while changing water pumps because they are very difficult to do with the pump in place. I patched the top hose with tape when it leaked at about 350,000 KM and then changed it when it was convenient

Wife's '99 Explorer has 185k on it, original hoses. I replaced the Serp belt around 80k, and I think it could stand to be replaced again. I check the hoses every now and then. No bulges or cracks, still soft and pliable. If you want the peace of mind, go swap them, but I'd say you are no where near needing to be concerned about it.

'98 Civic 165k and '05 F250 45k are also on original hoses. I did the belts on the civic when I did the timing belt and water pump at 125k when I bought it (interference engine - you don't want the timing belt breaking). Water pump was PM at that age as it is driven by the timing belt so you are right there already, plus if it leaks/seizes, it will take out the timing belt.
