upstairs radiator cold.

[microbar]

Upstairs boxroom radiator has run cold for 2 weeks now,
Have Checked for air but no air in the rad,
The thermostat is at the left hand side of the radiator, all others in the house are at the right, So maybee this rad is at the end of the system, Do i need to replace the thermostat ? thanks,
If the thermostat needs replacing,
Is it possible to remove without draining down,
Have a balanced combi boiler system thanks.

Just trying to work out how remove the thermostatic head,
To get to the plunger pin,
