Assuming the diesel is like a m103 or m104 its not bad at all. You need to get the plastic fan shroud out of the way and often the radiator too if its been on there a while and you really need to force it. If you want to leave the rad in you may need to cut down a 10mm allen wrench.
The belt usually provides enough grip to keep the pulley from spinning. If its not enough use an old belt and wrap it around the fan pulley and a few others. Then bunch up some extra and run it over itself to lock everything up. This should not the first attempt but as a last resort on a stuck bolt its better than rounding off the 10mm hex bolts on the back of the pulley.
