you can also take a shop towel bunch it up and then try to stop fan clutch while engine idling.this is not dangerous and works well.if clutch is bad a good temp fix is to use a large screwdriver to force open the bi-metallic strip at the valve end and slide a ceramic fuse in beside the pin this will lock it up to engine speed as long as it hasn't lost too much of the silicon.
