Jeep WJ Overheating

[Sony]

Hy.. my jeep wj overheating up hill and when i hold gas for more time on the road...coolant goes out when I stop the jeep but do not drain all the coolant ... I replaced the thermostat and new coolant fluid ... winter does not overheat only when it is more warmer or more hill....i hope its not blown gasket or something..

I have a 2000 Jeep WJ Grand Cherokee, I love this Jeep but I have been having an overheating problem. Normal running in town or out on the road during the winter no problem at all. I live in southern Nevada and the summers get a little warm.

Did you try to flush the system? Check also the water pump if defective, and if you have a clogged radiator.
