Detailed Product Description and Specifications

This A/C expansion valve is crafted from aluminum, providing a lightweight yet durable component resistant to corrosion. It is designed specifically for use with R134a refrigerant, the standard for many modern automotive air conditioning systems. The valve features a block type design with two mounting holes, ensuring a secure fit within the HVAC assembly. Both suction and liquid inlet/outlet fittings are female, with thread diameters of No. 10 and No. 12 for suction, and No. 6 and No. 8 for liquid connections, all non-threaded to accommodate insert o-ring seals. The included green o-rings (part numbers 24606 and 24608) help maintain a tight seal to prevent refrigerant leaks. This expansion valve meets or exceeds OEM standards, making it a reliable replacement part for Land Rover Freelander vehicles.

Common Issues Addressed by This Expansion Valve

• Inconsistent or insufficient air conditioning cooling
• Refrigerant flow restrictions causing system inefficiency
• Leaks due to worn or damaged expansion valve seals
• HVAC system pressure imbalances affecting performance
• Failure of original expansion valve components over time

Installation Notes and Tips

Ensure the vehicle’s A/C system is fully evacuated and depressurized before removing the old expansion valve. Verify that the mating surfaces are clean and free of debris to ensure proper sealing with the included o-rings. Use the two mounting holes to securely fasten the valve in place, and confirm that all female fittings are properly aligned to avoid damage during installation. After installation, perform a leak test and recharge the system with R134a refrigerant according to manufacturer specifications.
