How to know if your fan clutch is working:
With engine stone cold (and not running) reach in through the hatch and try to spin the fan blade. You should be able to move it with some resistance but if it free-wheels or spins easily it is not working . That is one common mode of failure.
Now start the engine. You should hear the roar of the fan for several seconds until the clutch loosens up a bit and then the roar will fade. This is normal operation.
If it roars initially and never stops roaring, then the clutch is not releasing. The clutch is locked up. This is another mode of failure.
Now go climb a large hill on a hot day. You should hear the fan kick in and start to roar after you get up the hill a ways. I often hear mine start to roar as I'm cresting the hill and starting on the way down. This is normal operation.
You shouldn't see any major fluctuations in the engine coolant temperature if your cooling system (water pump, thermostat, radiator and fan clutch) is functioning properly.
