my car temperature went up a little more than normal on the gauge on 2000 Ford Explorer

my car temperature went up a little more than normal on the gauge. After about one minute it returned to normal. but when we put water in the radiator we saw a leak . We could not see if it came from the radiator or the bottom hose. Is there any way for us to know where it comes from ?
