I'm used to the viscous fan on the Rover V8 being "on" for the first 30 seconds or so of a drive, then I'm pretty sure they are mostly free spinning unless the temps get up, and then it engages.
However, yesterday I noticed that my fan was always engaged. It was a cold start, and like normal, it didn't get to normal temps till 3-4 miles down the road. But the fan was engaged the whole 10 mile drive. And when I opened the hood to just double check, it was easy to tell that the fan was engaged, not spinning freely with the engine off.
Any thoughts? I don't know, but I hadn't ever thought about the possibility that it might break and stay on. I always figured a broken fan would never engage.
