By the way.... You have to put in an AC cancelling kit if you remove the compressor. Taking out the compressor reroutes the belt and I believe it will turn some stuff backwards if you do it incorrectly.
On another note, to clear up the clutch fan thing, your fan uses viscous fluid, which means it thickens up when it heats up as the fan spins. Jeep fans don't "un-engage" at high speeds. Basically the fan should almost free spin when it's cold, and be much harder to spin after it hot from running for a few minutes. When you go to spin it after you shut the jeep off, it should only turn about 1/2 a turn on it's own when you spin it.
Haven't you already flushed the block once? Did you actually run a coolant system cleaner in it?
Did you shoot multiple points on the block for hotpsots?
