Jeep Grand Cherokee 97 Overheating problem
My Jeep Grand Cherokee 97 4.0 6 cyl is overheating. It has the correct amount of coolant, and there is no leakage at all. However, the radiator isn't getting hot at all but the engine block is and the radiator hoses don't have any pressure in them after letting it get to around normal operating temperature when the thermostat is supposed to open and I just replaced the thermostat and gasket so it is not that. Is this a sign of a bad water pump or could it be something else?
I just want to make sure. Is it actually overheating? Or are you just concerned that the radiator isn't getting hot. It can take quite a long time for the thermostat to open if it's just idling. Even when it gets to operating temp. Also, did you install the thermostat correctly?

Thanks for the help guys, I forgot to purge the air out and when I did it stopped overheating but now I'm pretty sure the water pump is leaking because coolant is coming out right behind and below where the fan is and after idiling for a bit i started hearing this whining noise. any tips on how to get the water pump out easier or a link to a thread with this?
