It has been overheating.
Replaced thermostat x 4.
Repaired radiator x 2.
Repaired head.
Replaced head gasket x 2.
Overheating problem still has not been fixed.
It is still in the workshop.
A typical day out in the Discovery is that you travel 50 kms OK stop at a shop and then proceed with your journey and within 2 kms it starts to over heat.
After checking the thermostat housing when it has cooled down there is no water in the housing, meaning that the engine has no choice, but to over heat.
The dealership is now suggesting that an engine liner may be lose causing it to get hot.
I would be interested to know if anyone else has ever had such problems.
Your problem is not bleeding air from the system, when it has had work ie new thermostat, fill up to level in expansion tank, replace cap, remove small cap from radiator and run engine this should get rid of air locks.
