Can anyone tell me if the slant six ever had a "clutch" or "thermal" fan.
Is there any real advantage to installing one of these on my slant six ?

Yes, Some Slant 6 cars had clutch fans after 1979 or 1980. You can also find them on some Slant 6 trucks in the 1980's through 1987 if they had the heavy duty cooling option.

I don't know what advantages they might have. I'm wondering that myself and hoping someone will tell us. All I know is I have a few used clutch fans and the clutches on every one of them are kaput and do not engage when hot, they still freewheel. Silicone fluid leaked out of them I guess.

The only advantage of a clutch fan is that it freewheels at low engine temp, allowing the engine to warm up quicker, and the probably freewheel (or slip) a bit at higher RPM, freeing up some HP. I have never tried one, I have just gone directly to electric fans.

What type of electric fan are you useing?
Are you pushing or pulling and are you running any fan on the motor?
Been thinking about going electric puller with no fan on the motor but not sure how well it will work
Thanks

I run generic (Summit, or Mr. Gasket, $80-90) 16" fans on both my Darts with no mechanical fan at all. I run a puller on the '68 and pusher on the '64. I basically don't use them on the highway unless it's really hot, or I'm going up a big hill. Your running temps will be a bit higher than with a mechanical fan, but I believe that 200-210F is fine. No drag on the engine, except for a little from the alternator. I have a recored 2-core radiator in the '68 and an old (but rodded out) 3-core in the '64.

Take 'er easy,
