Td5 college problem

[Aerialdave]

Please someone shed some light on this??
Coolant issues with td5 discovery
Car starts,runs,drives, perfect

1)After driving radiators cold,(then gets hot when engines off)
2) heater works fine driving along but when stopped in traffic goes cold after 5 mins ( then hot when u drive again)

Checked thermostat
Done water test for contamination
No water in oil ???
Still loses water ?

Radiator blocked? Water pump?

Suggest flushing system out and make sure bled properly afterwards

Tiny hose leak - possibly where hose rubs somewhere.
Low level water causes airlocks...?
