Default Fan Clutch Brand

I am about to replace my fan clutch for the first time this weekend. Mine stays on all the time regardless of engine temperature. I'm trying to decide which brand to use. I will most likely order it from either Amazon, Summit, or go down to O'Reilly's auto parts and pick one up. I'm unfamiliar with the reputation for any of the summit offered brands.

Hayden?
Murray? (Oreilly brand?)

Is there a Ford Motorcraft fan clutch?

OEM would be best but brand is not that important with this, go for the best warranty. I always change fan clutches and water pumps together.

I went through fan clutch drama a few years back. I tried the Hayden and the brand from Auto Zone, these two brands are really all there were aftermarket, and had failures from both. Not sure if Motorcraft are any different. I'd get one local with a lifetime warranty.

Why change the pump and fan clutch together?

Since they are bolted together, when one goes, it can cause failure of the other. I was wondering how do you know the fan clutch is staying on all the time? Is it seized?

Yes. Regardless of temperature it's engaged all the time.

Well the fan is always going to spin, it really depends on how fast it spins - and that should depend on the temp. But it will always have a "minimum" speed that will be relative to the rpms.

Best way to see if the fan clutch is bad to grab the fan blade (when the truck is off, of course ) and give it a good spin. If it keeps spinning for more than about a 1/2 second its bad. If it grabs pretty quickly and stops, you are good.

The TSB in this caption explains how to test a fan clutch:

If it's actually locked up, you can't hurt it any more, so try to break it free (gently). This one was, but I still haven't started this engine, so IDK if it's back to working or not:

To find the Ford/MotorCraft PN so you can search for it on eBay/Amazon/Google, try these:
http://www.fordparts.com/
http://www.tascaparts.com/auto-parts...-v8-gas-engine
http://www.fordpartsgiant.com/
http://www.rockauto.com/

I would NOT mess with the WP unless it's leaking or not pumping. If you break those bolts, the truck will be down for a while. It's not THAT much work to pull the clutch again later when the pump actually needs replacement.
