you need a locking spanner for the water pump, theyre about £12.could probably make one. then you can undo the alan bolt through the fan.
tip, put a sheet cardboard sheet between the rad and fan, 2 reasons, easy to damage, and theyre sharp as razors!
the fan and cowl come off together, bit tight. no need to take the front off.
after this, its just a matter of undoing the same amount of boltholes that are on the new on.
dont forget the corrosion inhibitor/anti freeze
