Suzuki Liana, 2006, Radiator Losses Water

[muhammadnumairahmed]

"Why is my Liana radiator losing water if there is no internal leakage and the mechanic has confirmed that there is no issue with the gasket?" After 30 KMs in the city, Radiator need 0.5 Liter of Make-up water which becomes really hectic for me, Any suggestions or Solution and also please do recommend any relevant expert. Actions I have taken till date,

Radiator Clean and checked
All Internal Leakages checked
Even Heater has been cut down
Radiator Cap has been changed twice
But still confused ......

Does the system fill the expansion tank when hot and suck it back when cooling down?

Thermostat valve missing?

Does system build pressure (hard hose pipes)?

Change water to coolant... As leakage is found better through usage of coolant cause it leaves trace bit water doesnt, from where it's leaking.. the leaking maybe very minor and not visible with naked eye.
