Ok, over the last couple months i have ask question regarding my overheating problem on my 733i. I have replaced the Aux. Fan sqitchs witch help it form not going all the way to the red zone but it still gets very close to it. But now my question is, i found out that two years ago this car had its radiator replaced(band new, and it still does look new), but it look like its not as thick(or its has less width). Could the cause of my over heating problem be that my CLUCH FAN is not close enought to the radiator. Thus causing it not to pull enought air threw it? I do know that the cluch fan works, be cause on hot days, i can opent he hood, and put my hand at the back of then engine and fell lots of air being push.
