Had my car
(1981 E12 M535i) in the garage for the past week for some bits and bobs, mainly
sorting out the overheating problem. Spoke to my mechanic this morning and he
told me the viscous fan for cooling is not working correctly (not spinning at
the right speed I guess), I think he mentioned the bearings or something, I
have no idea whatsoever about the viscous fan system, all my previous cars have
had electric fan systems, are parts of it available separately or is it all one
unit? Which parts will I need to replace and are they expensive? Pete |

Hi Pete From other posts I have read it sounds like your viscous fan coupling has gone , basically the fan spins all the time then when the engine starts to get too warm a clutch kicks in and speeds the fan up to cool the engine down . Apparently if you roll a paper up and try to stick it between the blades when the engine is running, and it stops the fan then the coupling has gone ...This was replaced on my E34 a couple of years ago and looking at the reciept cost about £50 for the part (from and independant specialist) Edited by BMWE34sport |

Thanks, just ordered a viscous fan unit it was 75 pounds which is less
than I expected TBH hopefully this should cure the overheating, thanks
