We went to Fort Bragg, CA, last month and I occasionally heard a noise that sounded "fan belt" related. A "twinging" sound. I even checked the level on the power steering.

We just got back from another short jaunt. As we started the 190 mile trek home, I heard the noise and bothered to check power steering. Full.

The noise shut up and so we went on. About an hour later the fan clutch engaged. I checked the engine temp and it was absolutely normal. The clutch roared and then went to half speed and then got quite.

Maneuvering in yard comprehension came to me. The twining and twanging was constant. Fan clutch. When I shut it down it rattled on for about 10 seconds. A quick estimate says this one lasted about 2200 miles. I can't wait to lay on my belly board and change it.

These things really are a crap shoot. The performance varies dramatically within a given part number and even if you finally find one that engages and disengages when you want, the lifespan is an issue. It's not just a China thing since I've had the same issue with US built units. We are dealing with aftermarket part numbers which have very minimal is any quality oversight. If we can find a current OEM production unit, we will have much better luck no matter where it is made. I personally wouldn't rule out an electronically modulated viscous clutch that is used on many current model trucks.
