REPRODUCTION. You are purchasing one heater control valve. This is the valve that attaches to the heater core and controls the flow of hot water through the heating system. This comes with the coiled thermostatic line. Please compare to yours to ensure proper fitment. There are two styles for 1959 Cadillac Models. This valve pipe approximately is 5/8 inch (15.875 mm) in diameter. Replaces part # 3146277
PLEASE NOTE: For some models, the pipe on this valve may need to be straightened some in order to line up with the heater core. It is possible to slightly bend by hand, but if a more drastic change is needed it is recommended to heat the pipe to make it more malleable before attempting to straighten it. If this part is heated and shows heat damage on the piping this is NOT RETURNABLE.
