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.

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.
