Over heating 2001 Ford F-250

My ford F-250 has been purging out antifreeze, i had changed the thermostat, fan clutch,water pump,and the cap on the fill tank. It was still having the problem after all that, so i got some advice hear that there might be some air in the system causing this and the heart to blow cold, so i took the cap off, started it and let it cycle for a long time and got what i think was air out of the system. when i took it for a test drive it worked great, and even later that night it worked great. However when i got into it the the next morning to go to work the trucks heat was blowing cold and when i checked under the hood i noticed that there was a small amount of water leaking out from the cap again. I don't think it is a much as before but what is going on should i purge it again, could there still be more air. If so why did it work so good the first day after i purged it?

SOURCE: I have a 2010 ford

The performance of the heater indicates low coolant level. Pretty strange about the multiple water pumps, but if is is under warranty, you need to keep going back to the dealer. They must be missing something...

Check for cracks in the system. It sounds like you have too much air in it. If you are driving, does the temperature gage fluctuate? The cap is designed not to leak, but hot compressed air will blow by it. When it does, it easily confused as coolant "purging" out of the system, but really it is steam and air. By removing the thermostat, you are fully opening the coolant cycle and the water is free to circulate. Also, with the thermostat removed, the system can't build up enough pressure because it is open to the collector bottle, which in turn is open to the atmosphere. The system is designed to work under pressure so you should keep the thermostat in. That said, try to purge the system. Remove the thermostat, plug the overflow tubes, and pull a low vacuum on the reservoir (collector bottle). You want to make sure the reservoir is about half full. My personal experience is using about 5 to 6 inches of vacuum pressure for about 30 minutes. If there's lots of air, you will see bubbles in the reservoir. And as long as you have enough coolant in it, when you remove the vacuum, it will not draw air into the system, so make sure there's enough coolant in the reservoir. I am not sure about this truck, but some vehicles actually have a purge valve on the main coolant line close to the thermostat, and usually at the highest point in the system. It looks like a Schrader valve. So, if you have this, let the car cool down, put some rags around the purge valve, remove the valve cap and purge away (like letting air out of a tire). You'll have to do this a few time after driving to completely vent the system. Finally, if you do overheat again and start spewing coolant, before the car has a chance to cool down, fill the reservoir with coolant at least up to the hot level mark. That way, when the engine (and coolant) cools down, it will draw the fluid into the radiator. Otherwise, you just end up pulling more air into the system making the problem worse. Hope this helps.

FORD ESCAPE 2001 CONTINUES TO HEAT


Have you checked the thermo fans are cutting in and out. It may be the switch at the botom of the radiator or someone may have left the wire to the fan disconected probably when replaceing the radiator. or the A/C condensor might be blocked with grass stopping the air flow.

I have a 1993 ford conversion vAn overheats, new waterpump,thermostat. When going up hills it starts to over heat?


check for low coolant, the cooling fan clutch could be faulty it is free wheeling all the time, when engine is hot fan clutch should have some resistance when you turn it by hand. if all is good, your ignition timing could be off,your radiator and engine need flushing out,you could have faulty water pump, a bad egr valve will cause engine over heat if stuck closed which will engine combustion temperature get hotter.make sure you have 50 / 50 antifreeze and water in coolant system too much water in coolant system will cause engine over heat.also radiator pressure cap.check all those things i told you see what happens.

My 2001 ford Taurus heating temp gauge is not constant on dashboard. It goes up and down. I don?t have heat. Water pump, thermostat, in and out pipe and coolant are changed. Still no heat.


Start the engine when cool, remove rad cap and start engine and let it run with the heater on. (not defrost) Top up coolant as needed in rad, and let it run until either the rad fan comes on and off 2 or 3 times, or you can see increased flow in rad from thermostat opening. It will obviously happen after it reaches operating temperature, so watch after gauge gets close to there. Wait until you see that flow 2 or 3 times or fan comes on and off before you put cap on, and fill return bottle to proper level as well. That should cure it, by getting air out of system, and coolant flowing through heater core.
