Review on URO Parts 11 831 619 by Will Murphy

Works Great! Seems to be the perfect replacement for the factory fan clutch on my 1988 735i. Should work with any M30B35 engine. Even if your fan isn't completely blocked (i.e. a clear clutch failure), I recommend replacing it as they are all over 30 years old at this point. This new unit has greatly reduced vibration and my fan blade now spins without hesitation! I would highly recommend using this URO and saving some money - the only difference I could tell compared to the original was the updated cooling fin design. . Otherwise identical fit, form, function.
