fan clutch nut (QUICK QUESTION)

in the process of replacing all the belts and water pump, have really run into a wall... Bentley manual explains it as this:

(170-12)

"1. Place a 32 mm wrench on the fan clutch nut. Strike wrench quickly in a clockwise direction (working from the front of the car) to loosen nut. Spin fan off pump."

now... what exactly is it saying? is there some trick to it?

The only trick is that it is a reverse thread. Facing the car, you want to turn the nut to the right (clockwise) to loosen it. Giving it a sharp tap helps loosen it.

If it just slips, stick a screwdriver between one of the nuts and the shaft, put the wrench on then strike it while holding the screwdriver to keep the pulley from turning.
