Had head rescimmed new water pump removed thermo and car still overheats its driving me nuts pls pls tell me the answer
Before saying that might have a cracked cylinder head or blown gasket,I recommend you to check the following for clearing some doubts. Have you checked whether the radiator is clogged?,have you checked whether the matrix is not clogged? have you bled the cooling system? Also check when you accelerating with radiator cap on if the radiator hose upper expands,if so means that the engine coolant is pressurized and the problem is the cylinder head.

Hi,
I had the same problem with my 1993 Liberty LX. Remove the thermostat (located inside bottom radiator hose engine connection - take the connection off and thermostat is inside). Reassemble (minus thermostat), reconnect bottom hose. Slowly (very, very slowly) refill the radiator and remove the bleed plug ( located beside the top hose connection to the radiator - a black square plug with a phillips head cross in the middle). When the radiator is full and clear water (no air bubbles) is coming out of the bleed point, replace the bleed plug and then the radiator cap.
Run the engine for five minutes (approx) or until normal engine temperature is reached. Allow the engine to cool down and recheck the water level - fill if necessary ensuring that the bleed plug is open and clear water is coming out of that point. Replace Bleed plug and then radiator cap. Run engine for five minutes (approx) and then test dive. If the engine overheats keep filling the radiator until there are no air bubbles coming from out of the bleed point.
This fixed my overheating problem. Good luck and safe motoring.

Are you putting the thermostat in correctly? It it will not work backwards.
And to confirm that there isn't a different problem, take the thermostat out all together and see if it overheats.
Engine not fully warming up is not usually caused by the thermostat. Stats usually fail closed, not open.
You will want to check the water temperature sending unit or gauge after verify the water temperature with an external calibrated thermometer. You can attach and insulate the external thermometer to the housing where thermostat is located.
Reply back what you figure out. I will be happy to help you further.

The radiator is now plugged up, replace it before the overheating causes engine damage.

Sometimes fords can be tricky. Try to be sure that all of the air is purged from the system. I usually do this with a manual release cap. run the engine then slowly release the pressure. then the system will stabilize. If that doesn't help then you may have something restricting flow inside the water jackets through the engine. some shops have those nifty little cameras that they can run through the system to look for potential problems. hope it works out for you. I know how how much of a pain some of these problems can be. Good luck.
