Here is what the fan clutch looks like:
http://www.autozone.com/autozone/par...mString=search
It's purpose is to regulate the speed of the fan depending on the engine temperature.
If the clutch is frozen then the fan will always spin at full speed which will make the engine take a long time to warm up and rob gas mileage.
If the fan clutch is not engaging the fan when it should then of course you get various levels of overheating.
Here is a writeup on fan clutches, how they work and how to test:

Hey everybody, same kind of issue here with the "overheating". After about 10 mins of driving my gauge is already at half and my hose from the radiator to the thermo is bleeding (im assuming it builds pressure and chooses to bleed there). The cap hisses when i take it off and let it sit after a 10 minute drive which makes me think its an air issue. I filled the radiator up, and let it run for around 10 minutes and overtime the fluid started pouring out of the cap with the level of the fluid going up and down etc. Any ideas?
Thanks, Andrew
