You likely have an air bubble. Open drain, squeeze bottom hose till liquid comes out, then close, run, refill, repeat as needed.

Do the diesels have reverse-flow coolant as the petrol engines do? (thermostat at the bottom of the engine block)

If so, try this: Run the engine for 15 minutes with the radiator cap loose. Then, shut it down. The engine will then heat-soak and the thermostat will open up. (It didn't before, because it was in an air pocket)

Then, restart the engine...the open thermostat will allow coolant flow and you can top up as normal.
