Q: Ongoing coolant leaking issues - 2003 Grand Cherokee Jeep

About 4 months ago my jeep I bought (about 6-7 months ago) started leaking coolant which the mechanic fixed through the radiator because the previous owners wreck . He had to bleed out the power steering and the coolant and I had no problems after that for about 3 months . I had a coolant fluid low signal flash in my jeep one day and I put more in and it was fine for a week or two . Then it flashed again and this time i noticed its leaking now . Near the center underneath . I located it to under the belt . I also noticed that after driving a couple blocks the top hose gets really hot but the bottom hose which i think is the water pump hose is only luke-warm . I see a couple drops of coolant on top of the bottom hose from the belt that's how I figured out it wasn't leaking from that bottom of that hose . And looked under my jeep to see it pooling at the very bottom of the belt from something above it I couldn't see from the top . I think it's coming from the weep hole . Very confused on what All is wrong with it .
My car has an automatic transmission.
