Ford escape water pump

It could be the water pump, radiator, or cooling fan not working properly. If your heat is off it will not be the heater core.

Hello Justin.
If your thermostat has been replaced with the proper one your engine is heating up.
The problem then becomes twofold.
The amount of coolant/antifreeze flowing through the heater core or a problem with the airflow over the core inside the heater plenum assembly.
I would check for coolant flow through the core first.
If the heat feels like it is warmer coming out an outlet with the fan on a low setting rather than a high one your heater core isn't flowing enough.
To verify you can also check the two hoses that go through the firewall to your heater core once the vehicle has been warmed up, feel the temperature difference between the two. They should both be almost hot enough not to hang on to and close to equal temperature. A hand held temperature gun is really handy for doing this.
If one is hotter than the other your heater core has restricted flow and will need to be flushed or replaced.
Next is to check your temperature blend door operation.
Move the control to hot and cool and listen for the door to move and feel for the temperature to change, if it does at all. The fan on low setting is best to listen and feel temperature changes.
If you feel a temperature change or hear the door thump at each end of it's travel it is OK.
If you have more questions on this problem leave it in "add a comment" and I will return your question.

rad or bottom hose most likely,silly question.... have you got the right thermostat fitted?as that is where the temp sensor for the fan is situated,cos if its not opening the sensor wont get hot water.

SOURCE: What could make my 03 civic ex overheat and cool

I have a 2003 Honda Civic EX as well (158k miles). At first it would overheat when idling, and then my heater started working sporadically. It would blow cold air when idling, then hot air when driving. It would also cause my car to overheat. I would turn the temp to cold and the car temp would reduce. My coolant level would also drop to next to nothing every few months, but I never saw any pooling, or leaking from the radiator. I changed the water pump, thermostat, all the belts since I was there anyway, the water sensor and the radiator cap. After all this it was asymptomatic for 4 days, then the problems persisted. I took it to the mechanic and it was diagnosed with a blown head gasket. The test for it is fairly simple and runs ~$45 (1/2hr labor charge). I would try that before changing out more parts when you don’t need to.

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.
