Rock Auto has the Motorcraft for $180...anything but Autozone junk, no matter what the warranty. You'll need the warranty!

I was told, if the fan has resistance when trying to spin it when it's cold(motor has yet to be fired up), that the clutch is good. I get about a 1/4 rotation..

Don't believe it!

Okay, just wanted to use that smilie, never had a chance

But the point is, although I read several theories on "testing" the clutches, I didn't find any that were reliable.

They are stiff when cold, usually spin a moment when starting (especially cold weather), then stop unless hot.

I had the choice of several used ones, all felt a bit different, so I went with a new clutch (reuse my fan) from NAPA. It works. No overheating, and not constantly on.

I was surprised the other day climbing the big hill with relatively low strain (just wife and daughter with me, no trailer) and following slow traffic. Heard the fan kick on, so checked with Torque Pro and sure enough temp was about 212F and holding. It's a long, steep hill.

The way I justified the purchase: Regardless of what else is done, overheating kills oil and wears parts. Cooling MUST work properly.

Hope this helps a bit

Any one ever put an OBS (94-97 7.3) water pump and added a 6.0 fan to their SD? they direct more air, I had one on my OBS but disaster struck taking out my radiator, but the fan was to close . On a super duty I'm sure there's enough space for it.

A lot of the of guys use the 7.3L fan as an upgrade for there 6.0L. So I don't see that happening.

I'm talking about the actual fan not the fan clutch.

I believe it is electric and they switch to the 7.3L style. It's a BPD upgrade.

According to rockauto, they do have just the blade unit, then again, they also show selling a coolant filter too

Most places put on the coolant filter because of the EKR cooler and oil cooler. They plug up easy.
