The way I tell is two ways. First if the engine is cold and stopped take your hand and spin the fan,if it spins fairly easy you can bet the clutch is bad. The other way is block the radiator with some cardboard as tight as you you can and run the motor at high idle until the temp. gage moves to 3/4 or so hot (about 230-240 deg). Listen and you will hear the fan pick up speed and make more noise if it good. After test pull out cardboard and let motor run until it cools back down because a motor will get hotter after shutdown.
