Radiator does not require removal, nor does draining the a rad a requirement,
Under tray off.
Unplug the loom block connectors.
Remove the 2 x top bolts.
Remove the top rad hose.
If PAS pipe gets in the way, then just loosen the large bolt on the PAS pump.
Then just lift complete fan unit assembly upwards.
A simple 15 minute job.
As you have drained the rad it will now take you so much longer just to bleed the system.
