Mercedes Heater Valve O-Ring (E350) - Santech 2119970048

Product Information

The HVAC heater control valve regulates the flow of hot coolant from the engine to the heater core, allowing the system to produce warm air for the cabin. The valve opens and closes based on the driver's temperature settings, controlling how much heat is transferred to the cabin.

• Inconsistent Cabin Temperature: If the valve is stuck open or closed, you may experience fluctuating temperatures inside the vehicle, with heat not matching the temperature settings
• No Heat: A malfunctioning heater control valve can prevent hot coolant from entering the heater core, resulting in cold air blowing from the vents, regardless of the temperature setting
• Coolant Leaks: If the valve is damaged or has a poor seal, it may leak coolant onto the floor of the vehicle or around the engine compartment
