[QUOTE="astroboy, post: 601570, member: 4527"] You notice the crank fan spinning all the time because it's passive spinning due to the motion created by the internal shaft, u can actually use your hand to stop the fan, if the clutch didn't engage [I think only, DON'T TRY!! Dowan u to lose your fingers!] :4: Another method u can try is try spinning the fan with engine OFF. If the fan spins, then there's a clutch. Try it out! :4: That's a heat sensitive clutch and not controlled by any wire or electrical pulse. It kind of have a brain of its own.. :24: RR Fan clutch: [img]http://info.rockauto.com/getimage/getimage.php?imagekey=2420732&imageurl=http%3A%2F%2Finfo.rockauto.com%2FHayden%2F2991-2.jpg[/img] [/QUOTE]
