Just a very quick how to in a non spanner monkey way on the removal and refit of the aircon radiator if it becomes damaged.
Jack the car up and remove the under tray, prepare for hilarious rust in eyes moments..
Disconnect the pipe running from the intercooler over the top of Radiator to the Plenum, as this gets in the way big time.
Disconnect the pipes running into the radiator and watch coolant go all over your tools that you left under the car. move all ancilliary pipes out from the fan cowling area.
Disconnect the two brackets attached to the top half of the fan cowling.
From underneath the car un clip the flexible plastic guard that surrounds the bottom semi circle of the fan cowling.
Gently push up on the fan cowling so that it becomes un seated, it is easiest to see the two pivot points from underneath the car.
Disconnect the cable running to the electric fan on the side of the fan cowling.
The cowling should now, with a little encouragement lift clear of the engine bay.
Disconnect the two radiator restraint brackets. As you have already drained the coolant and detached the pipe, the radiator should just lift out, push it back towards the block and wiggle it if it is being stubborn.
Finally to the part you actually wanted to replace... There are bolts holding the Aircon rad to the sides, undo these.
WARNING The next part relies on your car having developed a fault that has caused it to leak all it's aircon gas, like a stone or corrosion. If your system is still gased I take no responsibility for attempting to un gas it yourself, or any harm caused by that process!
Disconnect the small ally pipes that connect to the RHS of the aircon rad and move them out of the way.
Tilt the aircon rad toward the block and lift clear, it shouldn't be stopped by anything as it just has side restraints and little rubber feet.
And that's pretty much it, putting it all back in and back together is actually a lot easier than taking it apart. After putting it all back together don't forget to tighten the hoses to the plenum, and to refill your coolant system, otherwise bad stuff will happen
Hopefully this will save people any head scratching about the best way to do it, as far as I can tell the only way is rad out, as there is no room to drop it down and the cowling contains an electric fan that stops it being slid back
Cheers

Oh, and big thanks to Steve Carter for answering my stupid questions and to my neighbour Clint, who despite driving a Pulsar is a pretty good guy with a spanner
