Coolant that is...

My '06 DDIS GV is losing coolant from somewhere. I need to top up the header tank from min to max every 4-500 miles, say 1/2 litre.

Theres no coolant in the oil. I cannot see any leaks from the radiator or hoses. No sign of dripping anywhere, no steam from exhaust...

Engine is running fine and no overheating. Interior of car not steaming up, no smells. No drips in footwell...

So where is it going?

Any suggestions please

Check your rad cap seals next.

The seal is on the pressurised header/expansion tank and it looks ok too with no obvious signs of leak, same as the radiator drain point.

Thanks for suggestion though

Do you have an overflow on the expansion tank, like the Jimny's?

Dont know about Jimny setup but mine has a lower pipe which goes to the bottom of radiator and a top pipe above the max level which goes to the top radiator hose. The cap is a pressure cap so the header must be pressurised when the thermostat is open. Theres no sign of the cap or pipes leaking...
