Vacuum tested working hot water valve for any 1969-73 Mercury Cougars or Ford Mustang equipped with factory A/C. This valve stops the flow of warm coolant in the heater hose, when the A/C is on. Has the original cast brass valve and vacuum pod. Used but functional, the reproduction version is very good, but has a black plastic valve, like the service replacement valves from Ford.
Replaces Ford part number C9AA-18495-D.
