1998 Ford Taurus routing heaterhoses

My anti freeze is leaking steady with the engine running. The water is coming out in the engine compartment on the driver side. There is some type of housing against the firewall where the brakefluid reservoir is mounted on. The straight flow comes out the bottom of that housing compartment. Do I need to disassemble the brake fluid reservoir and try to the housing off to get to whatever it is that may be leaking in there? There is no leak on the inside of the car. Thanks
