Electric Fan question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Are there any benefits to running an 16 inch electric fan on the outside of the radiator while running a stock clutch fan with shroud, (I think that would be pulling while the stock clutch fan would be pushing)

Motor is a 350 with 350 turbo trans and will have a 24" finned frame tranny cooler

The stock fan and shroud work by making a low pressure area just behind the radiator that draws air through it.
If this is not sufficient to cool a 350, then you have issues that should be addressed instead of trying to force MORE air through.

JMHO....

I agree with this. While it would not hurt anything to add an electric fan, why bother? IMO, it would just be unnecessary complication. I would save it for another project, or sell it.

BTW, your clutch fan is a puller.... an electric in front of the radiator would be a pusher.
