Sorry to hear. This happened on my brothers M3. Time to upgrade to the zionsvilleautosport super duty M5 radiator.

Oh yes. Correct. But I was thinking more along the lines of the plastic fan weakening over time regardless of it being used with a properly functioning fan clutch. Let's call it "plastic fatigue."
Bottom line is once one blade cracks off the fan is so out of balance that it instantly disintegrates. I'd opt for a metal version of this fan if it were an option.

I don't think anyone makes a metal one, but the plastic replacement is around $50-65.

Update... The total parts to be replaced... Radiator, upper radiator hoses, fan, fan clutch, water pump, belt... The fan exploding directly affected the radiator, the hoses as well as obviously the fan and fan clutch.

For what it is worth my Indy noticed a slight wobble in the water pump pulley. Not that it was the reason for the fan exploding but he did work on a 5 liter mustang in the past that repeatedly had fans explode. After about 3 or 4 fan replacements he found the source to be a bent shaft on the water pump pulley.

Anyway the cost of the replacement parts and labor is....$2,100.

I love this car... or at least thats what I tell myself. I will post again on this point.

I'm removing my fanclutch/fan before the AutoX season starts next month... just still not sure on what to do for a replacement electric fan...

Oh and sorry this happened... could have been worse though

Sorry to hear that. This could be a DIY job if you're up for it. Could you breakdown the costs if possible?

Thanks and good luck,
Jim

If I hadn't already spent money to replace my OEM one last summer, this *could* be the answer, but imo, WAY TOO PRICEY for my tastes. There has to be an option to just add an electric fan...
