Could be many things of course, not what you want to hear I know. I will assume the coolant level has been checked. I usually start with the thermostat because it's the most common and least expensive. If its leaking water/antifreeze, might be a hose or water pump. After that it could be low on oil or the cooling system clogged up,


Also I had this happen to me on a 2001 Intrepid. The A/C clutch went out and I lost air conditioning this past summer. It has this great/stupid design feature that when the A/C goes out it also kicks the relay and the cooling fans for the radiator also quit, causing the engine to overheat.


What engine do you have? -Jim


In my case over heating was caused by clocked catalytic converter! Cost me $180 to find this out! (I took it to the dealer and they diagnosed right) You may have same problem too! I changed myself and old catalytic converter tiny holes were totally melted and probably only 20% air was flowing.
