Hello everyone,
Sorry for all the posts. I'm just beyond frustrated with this job. 2010 Ford E-150 with 4.6. I drained the coolant from the radiator peacock when changing my intake gasket. Now I don't have any heat and the top radiator hose doesn't have any fluid at all. I over filled the reservoir. Ran it till it go warm/cold a few times. Revved the engine a dozen times. Disconnected the top radiator hose (while vehicle was off). Tried squeezing the top radiator hose. Nothing seems to change anything. I don't even know if I can trust the temp on the dash as I don't know where the sensor is is. I'm worried its will overheat the engine because of the lack of coolant. I have no idea what to do I'd appreciate any help.

 

If you can,,,,,,,,,,,,,,,take the top heater hose off, at the heater ,enough so you can let any trapped air out. When no more air comes out add to the RADIATOR. then let any addl air out again. That should allow most of the air out..

If the only way you can add to the system is through the overflow bottle, you may need to run the engine some until the thermostat opens and that will allow the air to come up to the top of the radiator and the coolant will go out through the bottom of the radiator to the engine. Wait until the engine cools down then add coolant as required.
Some thermostats had a bleed hole to allow the trapped air out sooner, don't know if your thermostat has the bleed hole. As the engine cools it will draw from the recovery bottle to fill the system. Just be careful and don't get scalded with hot coolant !

 

Thanks again @hanky Driving around and letting it heat cycle worked.

 

You knew what to do all the while , All you needed was a little encouragement.
Thank You for the update.
