coolant loss

I had a coolant loss in my 1994 Cherokee, turns out the hose clamp on the bottom radiator hose wasn't tight enough anymore . I too was wondering why I was seeing a little puddle of antifreeze under the Jeep, I popped the hood and heard a small leaking sound, turns out it was seeping ever so little from that bottom hose, I turned it a little and it stopped. check you hose clamps, those spring loaded type that are used, at least on my Cherokee aren't infallible

Good catch anchor that's another reason that alot of us prefer to use the worm gear clamps that can be tightened down good instead of relying on the spring ability to keep it tight. Also for the water pump and tstat housing outputs can usually have gunk build up on them and deteriorate which can also be addressed by removing the hose and taking some sand paper and going around the connection to smooth it out again.
