Volvo Radiator Leak that cant be found

#1

My S70 Volvo leaks coolant but we can’t find a leak. They have run a pressure test and nothing also we flushed out the radiator but still nothing.


#2

Heater core? Check all the hoses that handle the coolant (radiator to the engine to the heater core…)

Have you checked to make sure you don’t have a head gasket problem?

If all of this fails…there is one final option, but I am sure it will get me attacked here.
