Lightweight plastic fan with clutch?
We have all read the love/hate for stock and aftermarket fans
Ive seen cars with fans (white plastic?) like the one in the pic below..Some german cars and I think the 70s Capri?
Thoughts on one of these with a HD clutch that locked up long before the car got super warm?
Do fans these exist in sizes we need, can they be adapted to any shelf fan clutch. Other than the flexalite black flex fans Im not aware of any
Just excercising the few remaining brain cells

Lots of late model trucks have plastic bladed clutch fans. Not even that late model anymore, I think it started in the 90's on various trucks and RWD cars, maybe even earlier. I don't know which ones would work though. I know the fan mounting points on the clutch stayed the same for a long time.

I took this flex fan, and carefully removed material from the center until it fit the clutch on my 1980 Corvette:

I haven't installed and run it yet, but I'll let y'all know how it works out.

Will ck it out. Post count doesnt mean I know anyhing lol
Scotty let me know how that works out. I had one of those on my 'El for years lovedit.
moved plenty of air impossible to break it seemed. We used those on Saugus speedway cars that would see 68-7200 rpm all the time.
Never had a failure.
Fan on my 02 5.3 is metal, will run outside and double check. Dont care about some hp loss on a dyno its about bulletproofing that cooling system
Ive had metal clutch fans destroy hoods radiators take out water pumps etc not using one period.

CV67...just furthering this discussion with an anecdote;
Me, a Chevy guy through and through. For decades I had K-5 Blazers as my 'winter beaters'. All 350's
Once I had bought a used unit with a UGH! Flex fan....no shroud. so living in NO. VT. cooling is no issue...in fact, all winter I'd run around with cardboard in front of the radiator!
My Bro is moving apartments, naturally he borrows the 'Burro'.
On the Sunday, he returns my truck...he's got a sheepish look on his face.
"Hey Hal look at this"....YUP! the flex fan had 'left the building' and is sticking up thru the DOUBLE thick metal hood LIKE A SHARKFIN!
"It just exploded". He was under the gun to move...so he hit the local 'service station' (remember THOSE!) and got them to put a 5 bladed Chevy fan into it.
They laughed while they did it.
REALLY, REALLY hard to beat Chevy for reliable performance.
Unk

I have compromised the structural integrity of the fan by removing material in the center, making it fit the fan clutch. But, it is rated for 8,000 rpm, and with a 5,500 rpm redline on an old clutch, I doubt it will even see 4,000 rpm, so I'm confident it will work well. I'll start a thread on it once I get it up and running for a while this spring, so watch for it. See ya!

My Dad lost a blade on his Flexalite flex fan on his vette. Lucky it went flying down, and not up.
I had issues with a generic replacement fan for my junker Buick. Forgot to check the direction of rotation.....wonder why it seemed to overheat in just a few minutes???? ☹
No more junky replacement fans for me. 😠
