Land Rover HVAC Heater Control Valve - Genuine Land Rover BTR4022

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

About Genuine Land Rover

The same parts Land Rover used to build your vehicle are sold as replacement parts under the “Genuine Land Rover” brand. These are manufactured under Land Rover’s direction, guaranteeing top quality. As you’d expect, they also carry a premium price and are sold exclusively through the Land Rover dealership network.

Genuine Land Rover parts trace their origins back to the earliest days of the brand in 1948, when Rover engineers built the first Series I using robust, serviceable components designed for durability in harsh environments. Over the decades, Land Rover established partnerships with leading European suppliers to ensure consistent quality and performance. This tradition continues today, with Genuine Land Rover parts representing the official replacement components engineered to the same specifications as those used on the production line.

What many owners don’t realize is that Land Rover doesn’t manufacture most of these parts themselves. Instead, they design the components, contract trusted suppliers to produce them, and then verify the quality. Many of these suppliers have partnered with Land Rover for decades. In the industry, they’re known as OEMs (Original Equipment Manufacturers)—brands you probably recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. It’s not unusual to open a Genuine Land Rover box and find one of these brands inside—just re-badged with a Land Rover logo.

On our site, look for OE tags on product pages to quickly spot parts that come straight from the original manufacturers. Choosing these can save you a significant amount compared to buying them in Genuine packaging. For more details on how to identify OE and OEM parts, check out our OE Academy.
