Sometimes Older is Better

I never heard of these particular ones coming apart.... the stainless bladed ones are what I fear. I had 2 of those bakc in the 70's before putting this fiberglass one on the old Ranchero, and both SS bladed fans developed cracks near the roots of the blades; I luckily caught them in time. But your point is well made: we'll inspect this regularly.

Back then a lot of guys were tearing the motor mount rubbers from motors with too much torque & slamming gears. When the engine would twist the fans sometimes would hit the shrouds. Factory fans might chip up those shrouds but the fiberglass ones tended to disintegrate.
