Magic Fan Blade - now you see it, now you %&%^#

Wish none of you ever have any trouble with your fan blade.
:happens:

Yesterday I had the great idea of taking my 4R V6 92 Limited up to 4.500 RPM and suddenly heard a loud noise under the hood followed by something that flew from the front of the truck.

Immediately stopped and noticed that where the fan blade was supposed to be there was only space.......
:jaw drop:

Largest piece I was able to find was 5 cm long (this was the piece that was nailed into the inner part of the hood). All other pieces spread out like bullets through the engine compartment and amazingly damaged only two other things: the battery (4 cm wide hole on the side) and the shroud (only its frame was left).


Costs in the other side of the word (Argentina):

Bought the fan blade replacement for USD 80 (USD 173 at Toyota dealer) and still looking for a replacement for the shroud (Toyota dealer USD 123). Believe I can build something if I cant find a cheaper one. Ideas are welcome on this. :help:

Will soon post some pictures of the general damage.

By the way, what flew from the front of the truck was the hood paint.

PS: take a look at your fan blade every once in a while.

That`s gonna hurt the wallet!

Before replacing all those goodies I would reccommend that you check the fan clutch. It may be locked up causing the fan to spin at engine RPM at all times resulting in fan explosion. If you replace all the parts and the clutch is bad you may have a deja-vu.
 
This just happend to me. I was off-roading and fortunatly was able to make it back to town before a piece punctured my radiator. The only place I could find a fan and shroud is at the dealers. The wanted somthing like 210 USD for both. Actually it is more like 3 parts. The shroud is sold in two pieces. The main, top part is about $90 and the lower part is $30. My mechanic has advised me not to waste my mony with the lower part.

Also he, and two other individuals have advised me not by a "Flex Fan" at stores like Autozone. I am told not only that they don't improve performance, they don't work, as in they don't pull enough air over the A/C compressor and radiator, that could lead to future problems.

Currenlty, I bought an aftermarket radiator and went to the dealer for the fan blade and shroud (a friend was able to get me a disscount, thankfully). The fan clutch is in great shape, the previous owner had put a new one in a year ago. (I have only had my truck for a month). I would like to know where I find out how to do an electic fan conversion for when the clutch fails. Any info on the topic would be appreciated. Thanks.
