Hi,
to dismantle the rad completely you have to remove the bumper.
As I remember now, I didn't remove the rad when I was renewing the tooth belt.
At the bottom of the rad you find to further rubber bearings, fixing the rad.
Be prepared, that these bearings will be cracked.
You should also prepare new seals for the gearbox-oil-rad.
The thermostat was not seriously fitted, when the valve was bound downwards.
But the question is: Is there any need, to dismantle the coolant radiator? You can flush the system with special fluids as long as there is no thermostat fitted.
By the way: Tap the threads of the cover cap and insert new bolts with a smooth coat of ceramic or copper grease.
