I haven't read the whole thing as it was getting a little out of subject. But to answer the initial question. I received my 32 mm wrench last week to remove the fan during cold weather. Very simple. Put the wrench on the 32 mm viscous nut and give a good sharp hit on the wrench (clockwise) with a rubber mallet. I am not sure if there was locktight on the bolt or nut but it came off on the second hit. I don't think you could dammage the water pump by undoing the viscous fan bolt this way. Hopefully the DEF will warmup faster now.

i agree with Nathan just give it a wack ? you can take the belt off wont hurt any bearings then!"

Although with no belt, the fan pulley will just spin as you hit the spanner... :doh:
