OK. Poll time. With most of us seeing at least 2, and some of us seeing 50ish, how many have we seem in 50+ years in the condition (failure iminant) like the one Ken discovered?
I agree the design could be improved, but then again with millions of miles logged is the factory fan "broke"?
I've seen probably a dozen damaged with broken blades or melted in an engine fire, but never the errosion seen here. And yes, I've beaded them and looked.

That is too funny Dave. How about a slip on seat cover for shows that says --

"Corvair Safety Seat --
In the event of a rollover this seat ejects the passenger prior to the car rolling over on it's roof."

That way the next guy who says "Don't those cars roll over?" You can point to the seats and say "Yes, but it has the optional safety seats mandated by Nader."

OK Folks,

Just for the sake of argument and theory I am throwing this thought out for discussion / debate.

How about removing the stock fan completely, remove the fan bearing from the top cover, somehow mount a small electric fan to the top shroud and seal it if needed?

Wire it up to run when the car is running but not in the accessory position, figure out how to add a light on the dash to illuminate if the fan is for some reason stops working kind of like an idiot light.

At this point there would be no horsepower loss or thrown fan belts because the belt would be eliminated. If the car isn't air conditioned, the harmonic balancer could potentially be eliminated if the engine is otherwise internally balanced.

With a steady flow of air using an electric fan, getting stuck in traffic at low idle speeds would not be a concern on really hot days (maybe)

I don't know if anyone out there has already given this thought as an alternative or not. I have no idea if it is even a viable thought but after reading this thread and visiting the other mentioned thread, I thought this might provoke additional thought and input.

As for me, for now, I am happy with what GM designed for the car. I do however like the prototype made from a solid block of aluminum. If it were to move forward and become available (in aluminum or a composite of some sort), I could justify up to a few hundred dollars to purchase one, if for nothing else but to show my support for the effort.

Note:
The fan offered as an example came from e-bay and sells for under $20.00 [www.ebay.com]

OK, several things here.
For the poll I have cleaned and scrapped at least a dozen fans that looked good until I bead blasted them and there was a fin that was cracked at the outer end root. I have noticed more in the last 5 years than I have in the last 50 years.

This last fan the car has 68,000 miles and I'm pretty sure sure that it has never been apart! Repairs yes but it still had rubber o-rings! There was even gray matter in the oil pan! Tetraethyl lead for those of you that don't know what gray matter is in the oil pan.

As far as an electric fan it has been tried documented and proven not to be a viable option. I was part of the test team!
Matt, grab the info from Fastvairs and post it in the stickies.

As far as the title I did want peoples attention and at least to look at and know what you are looking at. I have seen to many bad magnesium fans lately to just let it pass.

As Far as removing the balancer and belt. You’d still need the alternator.
If an electric fan would work it would be ideal. it doesn’t provide enough pressure to drive the flow.

Okay, since we have already gone off the topic of exploding fans, I must say that I am really confused on the topic of electric fans not being viable.
I have read all of the post about pressure vs volume and all of that, but having come from PDX and knowing Eddie, I do not know why people say it does not work.
Unless someone is lying!
Maybe Rex or Duane could chime in here, but as I recall, Eddie'e car has an electric fan, and the story that I heard first-hand, was that he and 3 other full-grown men rode in his car all the way to "The Toss" and it never got hot.
So, how is it that many insist that electrics do not work, while others insist that they do?
What gives?
What is "special" about Eddie's set-up?

Re: Are You Driving a Bomb? [ mag fan '64-9 ]
Posted by: KiltedPhoenix ()

So... are you saying someone like me, who uses their car as a daily drive, year round, in New England, should NOT use a mag fan? My car is a 63 but somehow it has the 64 mag fan on it, I have 2 other fans, one from my 64 spyder parts car (mag fan) and one from my 63 parts car (steel fan). I've looked at the shape of the steel fan and thought it would move more air, but be heavier for my little 80 to turn, but then thought that I'm in N.E., not a super hot climate so I dont really need to move more air, so stayed with the mag fan. Is my fan grenading a real possibility? I really cant be with out my car very long as it is my daily driver and my other vehicle may not make it out of my driveway if there is snow.

I live in a place where even the people rust.

What about charging the battery?? Without the fan belt to turn the generator or alternator with the fan missing, it ain't going to happen.

People, it is real simple all you need to do is take a look at your fan. I said this somewhere before either in the original post or after. I never said anything about stop using your magnesium fan or stop driving your car, just look at them once in a while. If you feel you don't know what you are looking for find another Corvair person to help you.
I am going to be racing and driving my cars with the mag fans. Again a simple look, very easy to do, and the pictures I posted should give you an idea of what to look for other than just cracks.

Very good info Ken. I wonder if I need to carry an extra fan when I am on a trip. I'll put it with my fan belt, fuel pump, points/condensor/cap/rotor, rocker arm, oil and oil filter, etc. etc.

Now seriously folks, I asked early in this thread, is the steel fan the one to use?
