First of all thank you so much for your donation.I emailed you a diagram that goes with the instruction's You use a holding tool like they show in the diagram I emailed you and hold the water pump shaft then use a fan clutch wrench to loosen the large nut.

If you can hold the water pump shaft in place without damaging something you need you can otherwise you will need the holding tool in the diagram.But when you put the fan clutch back on the new pump your going to have the same problem with holding the new water pump shaft without damaging something you need to reuse.Also say's you have right handed thread's on that so left loosey would be correct.
