Once you remove the cowling around the fan you'll have a lot more room to work on it
Enda is spot on Chris, you will need the 32mm spanner and also a tool to hold the pulley in place if the belt is already off the car. With the fan belt on the car it should provide enough resistance to be able to give the 32mm spanner a swift slap with the hammer. They are a reverse thread. Give me a buzz if you have any questions. That looks nasty enough so don't drive it until you get it sorted. I would change water pump to while at it. Have in stock and there is always Valdas for fitting.
