It would be best to disconnect the coolant lines and flush the core after the radiator flush. This will clear any sediment from the core.

2000 Jeep Grand Cherokee getting hot replaced the thermostate and it is still getting hot what should you do at this point?

flush your cooling system, you may have blockage in your radiator not allowing the water too cool, but if the radiator is that plugged up its probably no good. look at the radiator to see if there is any corosion or small leaks in the little fins in the middle, i have had a few that were plugged so bad that when i flushed the radiator it leaked. if that does not work it could be the water pump. ive also had a plugged heater core, and extreme amount of rust, from poor coolant system management, plugging off water ports in the engine and in the head gasket on the engine.
