My '02 525i is starting to give me warning to check the coolant level. I just notice yesterday water/leaks around the neck of the expansion tank. And according to some previous reading it is one of the weak links the the E39 cooling system, along with all the locations shown in this thread. I'm about 95K so I think it is time to undertake the CN90 overall DY. One think I can not understand though. How in the word do you get to the fan to remove the bolts? There is barely any space for me to put my hand in between the fan shroud to be able to remove any bolt. Is there a diff between the 02 525 and the 98 540?
Am I missing something ?
