I have disappearing coolant from the system when the engine is run for a long time, short trips is fine but of long period it loses coolant and overheats.

I have replaced the Heater Hose and radiator cap (twice), can’t see any bubbles in the radiator inticating a head gasket leak.

Overflow remains full and when I top up the coolant the extra goes into the overflow and leaks out.

Can’t see any other leaks and no hissing from anywhere, none of the hoses and coolant residue of them.

Any Ideas??? Been going on for months now and suddenly it started getting worse, now it needs to be topped up once a week about 2 litres

TIA

genuine cap and right pressure one 120 or 140kpa, too many issues with aftermarket caps, and there were changes too the pressure after a set year, use vin too get correct one, check for crack top hose on radiator

you're definitely using coolant not just water?
