2001 Discovery II LE - creeping temp guage

Sure enough, I lifted the hood and was able to spin the fan between the radiator and the engine block with one finger. So fan clutch it is. And the coolant flush was a waste of money. I will update the thread once the mechanic gives it a once over to confirm.
I had the fan clutch replaced on my wifes 528i and about two weeks later the water pump blew. Bad coincidence or do these items go hand-in-hand. My water pump is only about 6 months old.

Also, did you verify that the electric fan is working?

A second look...
I took a second look at the fans. I can turn the viscous fan with one finger, but it does not spin more than a quarter turn before stopping when the engine is cold. The auxiliary fan in the fron kicks on and off with the A/C accordingly. So it may not be the fans after all. I will have to check the bottom of the radiator to see if it remains cold after the engine has been running long enough to warm up.
On a side note, my mechanic said he tests the fan clutch by seeing if he can stop the viscous fan from spinning while the engine is running. Can anyone validate this?

Your mechanic is a reckless guy, and will soon be known as "Stubby". A viscous fan fully coupled is 60 - 90% power transfer, and if some people claim that a fan is a 5 - 8 horsepower drag, well that could be a lot more power than a food processor. At normal "warmed up" operating temp, the viscous fan drops to 20% coupling. Let us say that it is 4 HP drag to start with. So would you try to stop something being turned at about 700 rpm by a 3/4 horsepower motor? How about a smaller motor? Just reach overhead at home and bring that ceiling fan to a screeching halt with your pinkky....
All kidding aside, don't try that a home, even with a welding mitt on. True you might stop it if it was bad. What if it a'int? Use a rolled up magazine if you must, but anything snatched out of your hands can damage fan blades or radiator.

Definitely pulling air into the grill. Trying to decide if an easy change out of the thermostat would be worth the money. Miamibritish has the one I need listed at $32.00.

See if there is a cold spot dead center of your radiator when it hot and engine off. Fan clutch will have a hard time locking up with no heat transfer. Best thing to due is replace your radiator, fan clutch, and use soft spring 82 cell thermostat, with age and miles on vehicle. Block test could give you peace of mind also, before you spend all that money on new parts.
