2011 Ford Falcon TX Valve: What It Does and How to Look After It

Yes, a TX valve is fitted to the 2011 Ford Falcon (FG/FG MkII). Technical sources including Ford’s workshop literature (Section 412-00 Climate Control), the Ford Australia Microcat parts catalogue listing “Refrigerant Expansion Valve” at the evaporator, and air-conditioning service data used by VASA/Autodata all specify a thermostatic expansion valve controlling refrigerant flow into the evaporator on these models.

On the Falcon, the TX valve meters R‑134a into the evaporator based on evaporator outlet temperature and pressure. That keeps vent temps nice and cold without freezing the core, balancing efficiency and compressor load. It’s typically mounted at the evaporator inlet by the firewall, where the pair of A/C lines pass through the bulkhead. When working properly, it helps the Falcon cool quickly in Aussie and Kiwi summers, and stabilises cabin temps during long motorway runs or stop‑start traffic.

As part of routine servicing, there isn’t a “maintenance” item for the TX valve itself, but a few smart checks help it live a long life. Keep the condenser clean for good airflow, don’t ignore cabin filter restrictions (where fitted), and have the system checked if cooling performance swings hot‑cold at random or the evaporator ices up. Any time the system is opened, a new set of O‑rings and drier/desiccant (condenser‑integrated on many FG variants) should be fitted, as per Ford service practice.

• Common fault signs: weak cooling at idle but too cold on the move, hissing at the firewall, frosty line after the valve, or odd high/low gauge readings.
• Replacement tips: recover refrigerant, remove the lines at the valve, replace O‑rings, torque to spec, evacuate, nitrogen leak‑test, then recharge by weight with the correct PAG oil per the under‑bonnet label and Ford specs.

If contamination is suspected (compressor failure, moisture ingress), the air‑con specialist will flush the lines where allowed, replace the condenser drier/desiccant, and verify the TX valve isn’t restricted. A tidy install with new seals and proper evacuation usually restores crisp, consistent cooling. Most owners leave this to a licensed air‑con tech, as it needs recovery gear, vacuum equipment, and access for the valve at the firewall.

Popular questions about 2011 Ford Falcon TX Valve

Where is the TX valve on a 2011 Falcon?
It sits at the evaporator inlet by the firewall, where the two A/C pipes pass through the bulkhead. Access is from the engine bay on most variants, though components may need to be moved for space. Always discharge the system with proper recovery gear before cracking the lines.

Do I need to change the drier when replacing the TX valve?
Yes. Ford service information and industry practice call for renewing the drier/desiccant any time the system is opened. On many FG Falcons, the drier is integrated with the condenser or available as a cartridge. Replacing it helps protect the new or existing TX valve from moisture and debris.

How much does a TX valve replacement usually cost?
It varies with labour time and parts, but expect parts, recovery/evacuation, drier, oil top‑up, and a precise recharge by weight. Pricing depends on workshop rates and whether additional items (like a condenser drier or contaminated lines) need attention. A quick quote from a licensed A/C specialist will nail it down.
