Automotive Electric 2-Port Coolant Control Valve for Audi A1 A3 A4 A5 A6 A7 A8 Q3 Q5 Q7 TT

The Audi coolant control valve is a compact, electric 2-port valve designed to precisely regulate the flow of engine coolant to the heater core. Crafted for a wide range of Audi models, this valve helps you achieve faster cabin warm-up, steady temperature control, and reliable heater performance even in cold starts. As a direct replacement, it restores smooth climate control without the hassle of diagnosing intermittent heater issues.

Benefits & Tips

• Restore optimal heating performance: When the heater takes too long to warm up or fluctuates with engine temperature, this electric valve provides precise coolant flow to the heater core for consistent warmth.
• Easy, reliable replacement: 2-port, 12V solenoid design with a 2-pin connector fits the specified Audi models and OEM references, making installation straightforward for DIY enthusiasts or professional technicians.
• Proactive maintenance tip: If your vehicle’s heater behavior changes after coolant service or at extreme temperatures, replacing the valve can prevent heater core stress and improve overall cooling system efficiency.
