i've developed my own style...

i've got a rover one piece shroud

four shroud screws which are allen key head.

i take the radiator out of the shroud to get it out, but still with it all jacked up,

just easier than manouvering over fan blades.

BUT

it all goes back in as one piece ie bolt rad to shroud and then juggle it over the fan and bolt up the shroud to bottom mount and drop motor back down
