Stop in for a cup of coffee

My Wife and Mom took my car in for a heater core change Tuesday. Dealership called and cant find a leak. Told them if you go anywhere past mid temp towards hot on hvac controls you smell coolant inside the car and you lose coolant from the radiator. They are still trying to find the leak. Will call me back on Monday.
At least the carpet is dry.
It's probably leaking out of the HVAC box drain.
