If you have one hose leaking, you should consider checking or pre-emptively changing all the hoses if you can. I had a radiator crack and a hose leak, and when I changed the radiator and the hose, other hoses started to give way as well, so in the end, just for peace of mind, I changed all the hoses. That didn't solve my problems, which turned out to be a failing fan, (but the system was thoroughly pressure tested by then....).
