Engine fan testing

Hey all, is there a way to check the engine fan clutch? I an not sure if the clutch is working. Do you know at what temperature the clutch engages? Thanks for the help!

Is it over heating? Usually you let the engine overheat a little and then turn it off. Then go out there and try to turn it and see if any resistance. Usually you can hear the fan spinning faster when the engine is hot (around 210-220) Remember most thermostats don't open up all the way til 220.

not overheating, but the ac is not cold when you are stopped or moving slow. The temperature will not go over 206*

this has an electric fan clutch. With the engine off won't it spin freely regardless of the temperature?

Should the fan come on when the ac is turned on?
