00 740iL - Overheating problem

I have a 2000 740IL, the engine has been overheating lately, i stopped and topped off the coolent but forgot to put the cap on it, stopped and filled it again and this time i put the cap back on, someone told me that it might have air in it (the system that cools the engine got air in it, and doesnt cool it) someone have any idea whats going on?

Hello, I hope this will help you out. Video of how to add coolant. Not saying that you did it wrong but the ball indicator is made known in this video and I found it to be helpful.


Also, This is a link on how to burp your system when air is thought or found in the coolant system.

U definetly have air in the system...Turn engine on and open up OBC in your cluster. Open #9...#9 will show your temperature...turn heater on to 90 degrees ..Open hood and unscrew the vent screw loacted by the expansion tank... Car will idle to about 100 to 105 c
..You will see coolant bubbles escape the vent screw... Now with your hand reach the lower radiator hose escaping the passenger lower side of the radiator.......feel the temp by hand..if it is COLd.. the Thermostat has NOT open up........Kepp bleeding until that hose starts to feel warm or HOT...once hot then the thermostat has opened up and coolant is NOW flowing thru ur sstem corrctly....and Now tighten up the vent screw and ur DONE!@!!!!!
ask me how I knwo...I have bled my 7 about 11 times for various reasons........Im a DIY pro!
