Mines origonal to the car i have never actualy taken a good look at my fan. From what im hearing is that the fan is comprised of two blades welded to the hub?
If it were once peace stamped steal of medum dencity rivited to the a central hub made to look origonal (i see no reason that it would ever fail) all welds are prone to failure from fatigue ( I take it the weld is were these blades are failing?) I would never put a cast fan blade in my car the process of casting creates an extreamly brittle meatal that is porus, unbalenced with tones of microscopic cracks and air holes. thats why air plane props are mechiend not cast.
