It is designed to free wheel until the engine reaches running tempture. The way you check the fan clutch is make sure the engine is hot, norther words go and drive it a few miles, then come back and leave the engine running, open the hood then stand somewhere where you can see the fan turning. Then turn the engine off and the fan blades should only turn about 1 time as soon as you turn engine off. If the fan spends several times then the fan clutch is bad. Replace fan clutch. Just be sure the engine is hot when you do this test.
