Coolant leak from rear passenger wheel underbody coolant AC and heater unit
Hello. I would need to know what kind of vehicle this is to be able to provide more information. Typically a leak in the rear of the vehicle can be a failure in the hose or in the rear heater core. A cooling system pressure test would need to be done if the leak cannot be easily found.
