Heater valves are essential components in a vehicle's heating system that regulate the flow of coolant to the heater core, controlling the temperature inside the car. These valves are crucial for maintaining a comfortable driving experience in cold weather. Vintage NOS heater valves refer to new old stock valves that are no longer in production but are brand new and unused. These valves are sought after by car enthusiasts and collectors for restoring classic vehicles to their original state. Vintage NOS heater valves are rare finds and are valued for their authenticity and quality in vintage car restoration projects.
