Recommend Clutch Fan Kit

I think I might need to replace the clutch fan on my 1966 Plymouth Valiant Signet 225 /6. There are different kits available and I don't want to get something too much but don't want to get crap either.

Thanks!

Hayden clutch fans are the way to go. They are available at all the local Oreillys,Napa,Autozones,etc. Check out their online websites.
Get one for a later model Dart.

I was not aware that a clutch fan would fit on an early "A" body slant engine. I did read that someone had put some year Mercedes clutch/fan on a slant.

Slants have the same bolt pattern as a small block,on the water pump. Generally slants have much more room between the fan and radiator. So you can use a small block,or big block for that matter,clutch fan. Team it up with the proper spacer to get it close to the radiator,and your golden.

PS: I prefer the stock,4blade fan on my slant. Lightweight,and does the job.

In my 64 valiant there is no way I could squeeze a clutch in there. Between the fan & water pump is a 3/4 inch spacer and the fan is within 1/2 inch of the radiator.

Lose the spacer,and get the shortest clutch from Hayden.
The shortest clutch they have is for a Jaguar,I've used them on small blocks.
There is also 3 or 4 different spacer widths.
Like I said,I'm happy with the 4 blade fan,so I have never tried to make a clutch fan work on a slant. But here are some options.
Apparently you can make it work,because the OP is already using one.

That's the one I have in my Sweptline truck - the 2765 Hayden with a 5-blade steel Mopar fan. There isn't much room there either. But the slant is tighter, maybe '66s have more space?

I thought the slant had more room,but I guess I got the 2 motors mixed up.
That's probably why I never install a clutch fan I my slant car.

Is there a fitment issue with the MoPar viscous (sp) set up?

Do you mean (SB) small block ?

Maybe someone with the JAG clutch and mopar fan can give him measurements from the front edge of the clutch to the mount face where it goes against the water pump pulley?

FLYNLADY, just measure what your precise allowable space between your water pump pulley front and your radiator is. You will need to remove your factory iron fixed airplane prop fan and snug two bolts back in the pulley/pump so as to have it flat when you measure.

IF you already have a clutch fan setup, just pull that one and measure its depth. Then get a standard duty thermostatically controlled clutch as a replacement. The thermo (built on the front) will deactivate the clutch when its not needed and save you HP and fuel. This is what all clutch fans went to by the 70s (thermo-activated viscous clutch).

Pic is of a hayden 2747 which is a HD unit for 440 truck and apparently fits my 360 duster.


The clutch is what designates your max depth as the blade does not stick fore or aft of the clutch. IN other words the clutch is the longest part of the setup when you use a normal clutch fan with it.

I just measured my TORQFLOW PN # 922705 020803 (standard duty thermo-clutch) and it is 3.3" total front to rear pad. That means you literally only need 3.75 inch from your pump pulley face to the radiator to run this clutch fan and get away with it. Nice thing is the fan runs a bit farther back on the clutch, so it will have .5" more space from rad (to the fan) than to the clutch front. I dont have much experience with torqflow

No, not SB, SP as in spelling error.
