I purchased a 32mm spanner from ebay for 6 and used a large flat bladed screwdriver to wedge between two of the 4 bolts on the front of the water pump. the 32mm nut is a left handed thread so undoes in a clockwise direction looking from the front of the car. once the nut is loose fully unwind it and you can simply lift the fan and viscous clutch out from behind the radiator. there are 3 allen bolts holding the viscous cluth to the fan. the replacement is simply the reverse.
I feel that need to be emphasized for a novice. I have a little trouble when putting it back on the WP thread: tight space makes it hard to line them up.
FYI: 1 1/4" open wrench fit on that nut too.
