NOVAPARTS Heater Control Valve for BMW X5 X6 (2004-2019) — 64116910544 Solenoid Actuated Replacement

This NOVAPARTS heater control valve (Part No. 64116910544 / 1147412166, EHV102) regulates coolant flow into the heater core to restore reliable cabin heat and HVAC control in compatible BMW X5 and X6 models.

When a BMW’s heater fails to produce warm air or the HVAC blower behavior becomes unpredictable, a faulty heater control valve is often the root cause. This NOVAPARTS replacement is designed to match fit and function for many E53, E70, F15, E71 and F16 chassis X5 and X6 models from 2004 through 2019. Built as a high-quality aftermarket alternative to OEM components, it offers the connections, solenoid action, and mounting compatibility required to work with your vehicle’s climate system.

How does this valve affect cabin heating performance?

The valve modulates coolant flow into the heater core so the HVAC system can deliver warm air on demand. When it opens, hot coolant circulates through the heater core; when closed, flow is restricted and the system produces less or no heat. A failing valve can cause inconsistent temperature, no heat, or a permanently warm or cold cabin.

• Direct coolant flow control to heater core via solenoid-actuated valve.
• Restores predictable temperature control when functioning correctly.
• Prevents unwanted coolant bypass that reduces heating efficiency.

Will this fit my BMW X5 or X6—what models are supported?

This NOVAPARTS unit fits a large range of BMW X5 and X6 years and platforms. It covers X5 E53 (earlier models) and later X5 generations including E70 and F15, plus X6 generations E71 and F16. Verify fit by comparing part numbers or your vehicle’s OEM valve shape and connector.

• Compatible model years: BMW X5 (2004–2018) and BMW X6 (2008–2019).
• Reference part numbers: 64116910544, 1147412166, SK416008, EHV102, 74896, V20771011C, 701-005.
• Check electrical connector and mounting points against factory part before installation.

What are the construction and reliability features of this replacement valve?

The NOVAPARTS heater control valve is manufactured to aftermarket quality standards with materials chosen for coolant exposure and repeated thermal cycling. It includes a solenoid actuator and valve body designed to match the function of the original unit so it integrates with existing HVAC controls. While not manufacturer-branded OEM, it aims to provide durable operation and consistent flow control.

• Solenoid-actuated valve body for precise coolant regulation.
• Materials selected for corrosion and heat resistance in coolant systems.
• High-reliability aftermarket build designed for direct replacement.

How should I replace it and what should I watch for during installation?

Replacement typically involves draining a portion of the coolant, removing HVAC or engine trim to access the valve, unplugging the electrical connector, and swapping hoses and mounting hardware for the new unit. Take care to purge air from the cooling system after reassembly and confirm there are no leaks. If unsure, have a qualified technician perform the replacement to avoid improper routing or airlocks.

• Drain coolant to below valve level to prevent spills during removal.
• Compare new valve connectors and hose diameters before installation.
• Bleed the cooling system after installation and check for leaks and proper heater function.

Who is this for: Drivers or technicians working on BMW X5 (E53/E70/F15) and X6 (E71/F16) vehicles from 2004–2019 who need a dependable aftermarket heater control valve replacement. It’s intended for those restoring heater performance or replacing a failing OEM valve—especially owners wanting a direct-fit, solenoid-type control valve listed under part numbers 64116910544, 1147412166, or EHV102. If you require exact fit confirmation, compare part numbers and connector details with your existing component or consult a professional installer.
