Another Overheating proplem

Ive had problem after problem with this 240, and once again, its overheating. First time, it was a bad fan clutch, so i replaced that. Now, its overheating if i maintain speed. If im on the highway, its almost to the last bar, but if im starting and stopping, its fine. Im guessing its because im reving it and its getting more coolant flow, something like that.

Right now its not connected to the heater core cuz its bad, and i dont have enough for some1 to tear apart the dash and replace it, but that hasnt had any effect on the car so far. And ive bled the air out of the coolant system.

Is this just another case of a bad thermostat?

Hey bud how long has it been since you changed the water pump and thermo? What I have done in the past is pull the thermostat and see if that helps anything if not then its in need of a pump or flush the radiator.

just do it all, water pump, t-stat and radiator flush. chances are you need them all anyways
