I had a 2007 Chevy Equinox that gave me a lot of problems with radiator hoses, electro fans and the entire cooling system, with it I learned some mechanics but I think this is something more serious and I have seen a lot of information here but I still think that I need some more practice, for now I'll start with the fan clutch and change the entire cooling system. This is a 2003 Sahara with 130k miles and it seems to have some pretty old hoses. But I'm happy to find this forum, it has a lot of information.

You might be right. If you haven't done much jeep repair take it to a reputable repair shop with jeep experience. Inspecting all hoses is great idea. And, change all the fluids.
