HELP! I've tried two different fan clutch removal tools from Azone and Schucks (to replace the water pump).

Azone had the right size to fit over the 4 pully bolts, but the wrong size for the clutch nut. The opposite was true for the Schucks set. That is one tool fit on the nut but none fit the pully bolts quite right...not that it mattered much.

The cheap thin Schucks 1 7/8" wrench fit the fan clutch nut very well at first, but warped out of shape when I applied torque, and subsequently rounded off the nut edges. Yes I applied clockwise force (left hand thread) along with some PB blaster.

Any one know of any tricks???
