Ford Escape 2003. Engine suddenly overheat. Water pump seems okay. Radiator seems okay.
Engine over heating can be caused by a number of things. When you say the water pump and radiator appear to be ok I am also guessing that you checked the coolant level to make sure it is normal.
If the level is low then you obviously have a leak. Insufficient coolant circulating will not cool the motor properly because it won't be able to draw enough heat out. If the level is normal then you need to check the thermostat to make sure it is opening properly. To do this, run the motor to temperature and check the top and bottom hoses. They should both be hot and firrm once the thermostat opens meaning the circulation loop is operating properly. If the top is hot and firm and the bottom is cold/soft or collapsed then the thermostat isn't opening.
If the thermostat is operating properly then you ned to look for some other obstruction or cause for coolant loss. Check the head/intake gaskets, hose connections, hoses, over flow tank, radiator fins, radiator side tanks etc..
Good luck.
Testimonial: "Thank you for your quick response. I will get the head/intake gasket checked."
If your coolant level is dropping you have a leak somewhere. You can either have the system pressure tested or visually inspect it. If you visually inspect it make sure it is running when you do because many leaks will only show while under pressure. If the intake/head gasket is leaking the coolant will burn up inside the motor and you'd never know it was leaking. More rare would be a cracked head, which I have experienced once over the years.

The coolant level also drops and there is no obvious sign of leakage. I also removed the thermostat and released the top coolant hose to the radiator to ensure the flow while the engine is running.
