best done from underneath mate
remove front undertrays and the one above the radiator
unplug fans and fan temp switch
remove the fans, 3X10mm bolts each i think
remove the two clamps on the top of the rad, 2x12 or possibly 10mm again each
now thw only thing holding the rad in is the pipes,

(wil probably need something to lever them off, or just cut them) remove them, lift the rad about an inch and tilt the bottom towards the rear of car, drop from underneath
when reffiting, soak the pipes in hot water for a while first
