Four Seasons Heater Valve Product Line Details
The Four Seasons Heater Valve product line focuses on providing precise temperature control components for automotive HVAC systems. The Heater Valve 74623 is part of this line, offering a cable-operated, non-bypass design that replaces original equipment valves. This ensures consistent heater control performance and compatibility with factory specifications.
Product Features and Specifications
This HVAC heater control valve features two hose connectors, each with an opening diameter of 0.625 inches (15.875 mm), allowing for secure and leak-free connections. The valve operates via a cable mechanism, providing smooth and reliable control over coolant flow to the heater core. Made from plastic, the valve is designed to withstand typical engine compartment conditions without corrosion. It is a non-bypass style valve, meaning it directs all coolant flow through the heater core when open, which is essential for effective cabin heating.

- Restores proper heater core coolant flow in Honda Civic and Acura Integra models
- Resolves heater valve leaks or failures causing inconsistent cabin heating
- Eliminates issues with heater control cable operation or valve sticking
