That clutch may get "loose", but it is still drawing loads of parasitic power. It can soak up 5hp before the fan even begins to turn. I got rid of one on my Subaru wagon, with 95 hp and loaded with work equipment there was not a whole lot of extra horsepower to just lose in a fan. I took it off (it also has an electric fan) and the extra power was immediately noticeable.
So losing the clutch fan is a win/win. You will save gas just from not turning that clutch all the time.
