Clutch Fan Install getting mucho frustrated - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Oregon 1967 GMC** · 11-09-2024, 10:18 AM

Could someone break it down the assembly order for this? I'm thinking I need studs because I cannot get the bolts in from the fan side o from the water pump.

Save yourself mucho frustration and get the studs. It's 10 times easier.

This. The last time I changed my fan clutch, I didn't know about the studs. Fiddly but I eventually got it. Told myself if I ever do it again, I'll get the studs.

I use studs on every vehicle I own, makes life way easier.

**Oregon 1967 GMC** · 11-09-2024, 02:37 PM

Copy that. Thank you I'm getting studs.

I used studs on my 67 327 as well. Much easier to line up the clutch under the shroud

Napa has a kit with everything you need.

You're not putting that spacer back, right? I believe those are only for flex fans replacing thermo clutch fans.

Good point, that spacer should not be needed. The real test is whether the fan blades are roughly half-in, half-out of the shroud opening.

I do need that spacer to reach half in half out position in shroud. Hope i can find studs that long. I'll look at NAPa because O O'Reilly only had two inches

I ordered this from Summit. Hope it works

It didn't work. Going to augment shroud

I couldn't tell by the pic, and don't have the particulars off the top of my head.... But is there a chance you have a short water pump, and a long water pump might put everything right?

EDIT: This might help:

**Steeveedee** · Today, 02:45 PM

^ Interesting pic. My '70 BBC has a short water pump.

**Stocker** · Today, 04:14 PM

Well, the OP's '67 should have a short original WP -- but over the years, things can change.

**Steeveedee** · Today, 04:59 PM

What's worse is that my fan clutch is about 1/2" from the radiator. That's the severe duty clutch, though, which has fins that stick out pretty far past the fan mounting flange. I ended up just making a shroud from a piece of aluminum strap.

We haven't seen the OP's shroud. Maybe the deeper 4WD shroud would work?

I agree. I've tried both ways and studs are definitely the way to go.
