No Power and overheating !!!

I have a 1996 jeep Cherokee Sport 4.0 litre. It has no power when going up anyhill. I just got the driveshaft and u joints worked on. I left for it alone for 2 months while i was away for work and took it out when i got back and i lost all power going up a hill and the radiator hose flew off. I put a new heater valve in it and fixed all thr hoses but it still has no power in anytype of hill situation and it will just overheat or i dont make it up the hill. Any suggestion would be helpful thanks.

you could have a partial plugged converter?

What other problems are you experiencing? (starting idling, gas mileage???)

Check the thermostat first. It is inexpensive also.
