- O-rings included for sealing at installation
- OE-style replacement for select Land Rover front A/C systems
Fitment and Application Details
Compatible with select Land Rover HVAC systems, this part is used in front-position applications on the LR3 and LR4, and in Range Rover Sport models across the listed years. Fits 2005-2009 Land Rover LR3, Front. Fits 2010-2016 Land Rover LR4, Front. Fits 2006-2013 Land Rover Range Rover Sport, N/A. Part number 999388 is also referenced for service and catalog lookup, and 999388 should be verified against the vehicle’s original A/C valve configuration before installation.
This part cross-references Genuine JQD500010 for the same application.
What This Part Helps Address
- Weak or inconsistent cabin cooling
- Improper refrigerant metering at the evaporator
- A/C performance issues caused by a worn internal valve
- Temperature fluctuations during compressor operation
- Service replacement for leaking or restricted expansion valve assemblies
Installation Notes and Tips
Confirm refrigerant type, port layout, and valve style before installation. The liquid inlet and outlet thread diameters, suction port dimensions, and included O-rings should be matched to the original system specification. Because mounting hardware is not included, reuse or source the correct vehicle-specific fasteners as needed. After installation, evacuate and recharge the system according to factory service procedures.
Quality Assurance
