Hi - Dave here, contributing to RepairPal and providing expert advice since 2010. If you have coolant getting into the passenger compartment of the vehicle on the passenger side, it would sound to me like the heater core is leaking. This would not be intermittent though. It would happen pretty much all the time the engine is running with coolant circulating. I do not know of a "back radiator cap" that could leak inside the vehicle.
