Womala A/C Expansion Valve JQD500010 C2P8263 for Jaguar XK F-Type LR3/4

Product Details: A/C Expansion Valve - JQD500010

This A/C expansion valve is a precision-engineered component that regulates refrigerant flow into the evaporator core, ensuring optimal cooling performance and cabin comfort. It is a direct-fit replacement for vehicles equipped with front air conditioning systems.

Core Function: The expansion valve controls the amount of refrigerant entering the evaporator by sensing temperature and pressure conditions . When refrigerant is at the correct temperature and pressure, the valve opens to allow flow; when conditions deviate, it modulates to maintain optimal cooling efficiency. This precise regulation ensures consistent cabin temperature and prevents evaporator freeze-up.

Failure Symptoms:

• Warm or insufficiently cool air from vents 
• Intermittent cooling or system cycling on and off frequently 
• Frost or ice formation on evaporator core 
• Poor A/C performance after compressor or condenser replacement
• Visible refrigerant leaks in the evaporator area

Installation Note: This component is located within the HVAC housing and requires significant interior disassembly for access . On LR3/LR4 models, replacement involves removing the instrument panel and related interior components. Professional installation is strongly recommended.

Note: When servicing the A/C system, it is recommended to replace the expansion valve whenever the compressor, condenser, or receiver/drier is replaced to ensure optimal system performance. Always evacuate and recharge the system with the correct refrigerant type and quantity after installation. Verify compatibility using your vehicle's VIN number before purchasing.

A: Signs of a failing bumper bracket include visible damage or deformation, misaligned bumper panels, unusual noises from the front end, or if the bumper appears loose or sagging on one side.

A: For optimal results, we recommend professional installation. Key considerations include ensuring proper alignment of all mounting points, checking for additional damaged components, and verifying all fasteners are properly torqued to specification.
