Fan/fan clutch for 71 C10 with 350 HO with serpentine belts
 

Hi All,
Just had a GMC shop install the 350 HO turnkey engine in my 71 C10. They put in a new aluminum radiator but ended up installing a direct drive fan. They say they couldn't find a fan with a clutch that spun the reverse direction and had enough clearance.

Does anyone have this setup? Any thoughts on parts to use?

Thanks,
Jeff

You're probably going to have to use an electric fan set up on your aluminum radiator. A dual fan set up with shroud will be ideal for cooling your engine.

I don't know why a fan and clutch from a 87-95 wouldn't work. A similar van may be even smaller. Or a S10 4.3 style with screw-on fan (but you would have to change the water pump) is not as long. Do you have any photos?

I have a serpentine setup out of a 90 suburban with a 350. I couldnt use the stock one as it was to big for the shroud. I went with this one, from summit racing. Flex-a-lite Reverse Rotation Clutch Fans 5917, Im not sure how well it will work as I have only drove the truck 20 miles or so. I didnt want one without a clutch. Might be an option.
