There’s loads of threads in searchbar (top right) on it as most of us have done it at some point. It’s not as bad as you would think once you get stuck in. If you go full removal good idea to place the bits in the boot as you disassemble, then it goes back together quicker in reverse. Even LandRover eventually used the hole cutting method in the end
 
+1 its an easy job to by pass under bonnet
Wish I saw this before I started tearing the dash apart! Is it as simple as piping the internal (behind firewall )pipes to eachother and the external (engine loop) pipes to eachother?

Made a start today, got some bits off but got stuck because I don't have any eTorx sockets. Got some coming tomorrow.

Looks like the butcher has already had a go at this before, cut metal and quite a few missing screws:

No need to link the internal pipes. Use compressed air to blow the coolant out of the heater matrix.
