I have a 2000 Xedi. Normally a radiator has a cap that releases pressure at a specified psi. How does excess pressure get released from the Freelanders cooling system? 
You have a expander tank which is under pressure, but I see no relief valve/system to release excees pressure... unless I cannot see it???. I have a slight water leak at times between radiator tank and radiator core (which is crimpted together and sealed by an o-ring). My thinking is that excess pressure causes this slight leak. On towing a caravan up a long hill the temperature tends to rise, and since the last incident I have had this leak. I need to top water up every 1000km or so with a bit, so it is not losing much. Any advice will be appreciated.
