Engine Cooling problem
1997 BMW 328 6 cyl Two Wheel Drive Manual 106000 miles
----------------------------------------------------------------
Twice within about a month, the fan blades have all broken off. Both times it occurred when making a rather quick start after stopping. We have been unable to identify any type of obstruction or foreign object causing the problem. What's the cause?

get a good oem part, some subpar parts can handle the speed.

is it an electric fan or belt driven?

Check the motor mounts and be sure they are not broken.

thats what i was about to suggest, but i figured it may be electric and tat wouldnt make a lick of sense

ive broke a shroud before with the metal ford blades from stamping and the rear squats and engine comes up.

Thanks! New motor mounts seem to have corrected the problem.

Another successful repair!! Good on ya mate.

glad to provide you with assistance.

try to pass the word!
