Otherwise you'll need to loosen the fan bolts not all the way out and use a screw driver for leverage and get a wrench on the big nut. It does depend on the type of fan you have.

First off, I always pull the radiator, seems like with that engine so tightly stuffed in there, it's the only way to make any room to work with. Remember it has 3 (yes, three) water hoses connecting to it, also when you put it back in, I use electrical cable ties to secure it (makes the next removal easier).
The fan is easy once you get that out, it's the pulley I never could get off!!! The manual suggests you secure the pulley in order to loosen that effin' bolt...
I still couldn't get it off, I ended up taking it someplace.
Hope you have better luck, but yeah, pull the radiator and shroud out of the way.How do I remove the fan in front of the pulley on my water pump, so I can change my water pump? 91, 318i?These fans are called the viscous fan,there are 4 ten mill bolts on the front of the fan and you have to hold blades of the fan with 1 hand and with the other loosen the bolts you will need to use a socket and a rachet but it is very tricky and to do it correctly you will need some mechanical experience so i advice to take it to your local garage otherwise in the long run you do some serious damage to youe engine if you do not fit it back correctly,How do I remove the fan in front of the pulley on my water pump, so I can change my water pump? 91, 318i?Hi Bill, There are many types of viscus fans %26amp; not sure of yours, does it have a large nut-head between back of fan %26amp; pump?

Good luck.How do I remove the fan in front of the pulley on my water pump, so I can change my water pump? 91, 318i?Do you have the viscouse clutch type fan, ( can you turn the blade freely by hand)? If so you need a 32mm wrench with a slight off set. available at halfords. Turn the large nut behind the clutch unit clockwise (lefthand thread). Should be out your way then. Otherwise its a fixed fan, make sure you got all the bolts, and some carefull persuasion.
