Hmm... You can do it yourself, it is a pain to do though, you need to get the front well elevated, drop the tray, remove the fan plate complete, out under the car (hence the need to elevate it so high) then set about removing the rad, hoses first then free the radiators (multiple), free the cowling, separate the radiators, remember to remove half of Thetford forest from between them! and eventually drop the main one out of the bottom. At the very least you need to remove the grille but I removed the whole bumper as I had a list of jobs to do while I was there.
The radiator main bolts will likely snap, the cowling (tiny) bolts will crumble and the tray fairing clips will mostly disintegrate; it is a pleasure when it is all back together though.
