About this part

Climate Control Valve
What this part does
The heater control valve regulates the flow of hot engine coolant into the vehicle's heater core to provide cabin heating. Mounted in the engine bay near the firewall, it uses electromagnet solenoids to open and close internal plungers based on electronic signals from the climate control panel. When this component fails, the vehicle will typically experience a complete loss of heat, heat stuck on maximum at all times, or a severe temperature imbalance between the driver and passenger side air vents.

Before you order
The BMW 5 Series (E39) utilizes a dual-solenoid valve configuration to support the factory dual-zone climate control system. Before installing the replacement part, inspect the electrical connector on your vehicle's wiring harness; a leaking original valve can sometimes force coolant into the connector pins, causing corrosion. The cooling system must be properly bled according to factory procedures after this valve is installed to prevent trapped air from causing erratic heating or engine overheating.
