i flushed the radiator yesterday and attempted to put fluid back in but it wont take it without the upper hose off...I just had the thermostat,water pump and radiator changed and after having mechanic look at it found out I dont have a blown head gasket..my front fan wont kick on either so I'm confused and need answers please help!!!!
I have a 97' 528i wont take antifreeze keeps kicking it back up unless i undo upper hose!!!!?
The motor is cold, so the thermostat is closed. It won't let the air escape and the coolant get down into the block. Just go slow, with the engine running, and it'll eventually take it. When it seems full, fill the expansion tank completely. As the system heats-%26amp;-cools, the last little air bubbles will work outta the system when hot, %26amp; suck more coolant from the expansion tank as it cools. Might take a couple of expansion tanks refills to work all the air outta the system.
The electric fan is controlled by a temperature sensor somewhere, and the fan also only works when the system is hot.

There is a bleed screw on top of the tank where you put in the coolant you have to remove/loosen that screw to add coolant.
The fan has a temp switch that could be bad. The fan should come on when the A/C is on, if it doesn't you have a bad fan or something else.
