It is imperative to realize that @AlanR here is not merely trying to sell a repDVD.
In order to perform this job, the proper documentation is a must. Swapping the radiator as such is not a big deal, but according to the DVD, refilling the system requires vacuum.
Some people will probably chime in and say that there is no need to use vacuum. However, the cooling system on the LC engine holds a small amount of coolant. This means that the channels holding the coolant are tiny, and there are probably several bends and kinks in the system, offering plenty of options for trapping air bubbles. So neglecting the proper procedure may become very expensive....
I don't have much experience with computers from the fruit company, but I understand others make the RepDVD work by loading the files onto a memory stick and then install the files on the HDD. And then use Windows emulation on the MAC to read the manual.
Lacking access to the manual and perhaps lacking the equipment for vacuum filling system I humbly suggest it will be cheaper and safer to let the dealer do the job.
