E34 M20B25 Fan Clutch

[WhiteTip]

Thanks for the Showru night. I had move a step further now... Thanks for the sifu on the clues..... I did my first DIY last Sunday but it failed... :cry: I dismantled my E34 M20B25's fan (some more kena burned by the hot steel water hose, some more scratched whole hand).. and then only i realised than my fan is attached directly to the nut. I couldn't find any place where i can open up and insert the silicon gel into the fan clutch. Anything missing here?? Please shed the light... thanx.
