Fan to Fan clutch Bolts
 

Can anyone tell me the bolt size for attaching the Fan to the Fan Clutch, my truck didn't have a fan clutch so I got a new fan and clutch but both came without bolts, I see Dorman 23733 is for the clutch to water pump but I can't find which bolts attach the fan to the fan clutch.

Any help would be great
Thanks

Pretty sure that they are 5/16"-18 by about 1/2" or 5/8" long. Go grab some bolts from your stash and check it out.

Where did you get your fan and clutch? Do you have any part numbers? Looking to replace what a PO did to my truck with a stock setup.

I used my stock 7-blade fan and bought a new HD clutch p/n 2747 made by Four Seasons. It was a direct replacement for my failed OEM clutch.

... here's a link to one at Summit, about $40 for the blade. I've bought them at Advance Auto. I think the 7 Blade on the Blazer is original and a 7 blade Dorman replacement on the GMC. I like them, they run quiet and move a LOT of air.
