My car keeps overheating. It seems the antifreeze keeps coming out from the white reservoir. It seems to me that the pressure has cost to push the antifreeze up where the cap or the open hose that is attached with the white reservoir. I know it is not the thermostat because the thermostat hose got warm after certain amount of time. Also, the hose from the engine block that attached with the radiator is also hot and both fans are turning on. Although I did a coolant flush yesterday and that is when the issue started. I am not sure if there is a trap air in the system. I am not sure how to bleed the radiator, but would like some instruction how to bleed an air pocket on a coolant system.

Good morning.

It sounds like you have more issues than bleeding. You have pressure in the system that does not belong there. It may be a leaking head gasket. I suggest you have a leak down test done to check to see if there is a leak. It is a test where they remove the plugs and insert shop air into each cylinder and see if the coolant moves in the radiator. That will confirm it has a failed head gasket.

As far as the bleeding sequence, all you need to do is top off the radiator, run the engine at 1,200 rpm's and keep and eye on the coolant level and add as needed. when you get heat in the car then you have no air in the system.
