Heater Control Valve for 1955-59 Chevy Truck
New water control valve for use with deluxe type heater. Mounts inside of heater core box. Many times this is the cause of water leaking from the heater box. Tubing size is 5/8" as used in 1955-57 trucks but will work equally well on 1958-59's. 1958-59 uses 3/4 tube.
