ok my 525i overheats at idle. fan spins with resistance so i dont think its the clutch. just nearly took apart the entire engine cleaning and what not new head gasket. new thermostat, just flushed the coolant + flush cleaner. now when it overheats at idle it will go up to red and go back down, kind of like a cycle within 5 or so minutes . also if it goes up to red or near i gas it a few times and it goes back down. im thinking air pocket. am i right? if it is whats the best way to bleed it out?

Hey, I had the same problem. When you put your coolant in you have to unscrew the cap on the black hose line as well as the large and small cap on the tank and then ( this is what the guy at the bmw dealership told me ) fill up the tank thru the small nozzle.

Oh and dont lose the little black caps accidently like I did. Its a headache to find and replace them
