You can check the function of the fan clutch by doing a simple test. Start the car, let it warm up, turn on the A/C and watch the temp gauge. When it gets near 100 C bring the revs up to about 2000. You should be able to hear a turbine like fan noise. Keep the revs at about 2000 until the temp drops. You can make this happen quicker by killing the A/C and turning on the heat at max in Econ mode. If the fan noise decreases, then for all intent and purposes, your clutch is OK..
