2022 Ford Ranger TX valve: what it does and when to service it

Yes, the 2022 Ford Ranger uses a TX valve (thermostatic expansion valve) in its air-conditioning system. This isn’t guesswork—Ford service literature for T6 Rangers (Workshop Manual, HVAC section 412‑00) specifies a block‑type A/C expansion valve at the evaporator inlet, and Ford’s parts catalog for 2019–2022 Ranger variants lists an “A/C Expansion Valve” for this platform. Major aftermarket catalogues for Australia and New Zealand also carry Ranger‑specific TX valves, reinforcing that this model is TXV‑equipped rather than an orifice‑tube setup.

The TX valve’s job is to meter refrigerant into the evaporator, keeping superheat in the sweet spot so the cabin gets cold air without icing the core. On the 2022 Ranger’s variable‑displacement compressor system, the TXV and the climate control module work together to keep pressures stable, vent temps consistent, and fuel draw sensible—even when the ute is idling in traffic or towing up a hill.

Telltales of a crook TX valve include weak cooling at idle then over‑cooling on the highway, evaporator icing, rapid cycling, hissing at the firewall, or odd high/low‑side gauge readings. Before blaming the valve, a tech should rule out low charge, a blocked cabin filter, condenser airflow issues, or a sticky compressor control valve.

• Replacement basics for the Ranger: recover refrigerant, remove the cowl/trim to access the evaporator inlet, replace the TX valve and O‑rings, and torque to Ford spec. If the system’s been opened, fit a new receiver‑drier/desiccant (often integrated with the condenser on modern Rangers).
• After refit: evacuate for an adequate time, recharge by the exact mass on the under‑bonnet label with the correct refrigerant (R‑1234yf on most late‑model Rangers in AU/NZ) and the specified PAG oil balance. Leak‑test, then verify outlet temps and pressure stability.

There’s no routine interval for replacing a TX valve on a 2022 Ranger. Treat it as “inspect if symptomatic.” Good habits—keeping the cabin filter fresh, ensuring condenser fins are clean and straight, and running the A/C regularly—help the valve live a long, drama‑free life. If the compressor has failed or the system’s contaminated, the TXV should be inspected or replaced as part of the clean‑out to avoid repeat issues.

Popular questions

Does the 2022 Ford Ranger have a TX valve or an orifice tube?
It’s a TX valve system. Ford’s workshop documentation and parts listings identify a block‑type expansion valve at the evaporator inlet on T6 Rangers, including 2022 models.

What symptoms point to a failing TX valve on a 2022 Ranger?
Common signs are inconsistent vent temperatures, evaporator icing, weak cooling at idle, unusual hissing at the firewall, and abnormal gauge readings. Always check charge level, airflow, and compressor control before condemning the valve.

Should the TX valve be replaced during a routine A/C service?
No. It’s not a scheduled item. Replace it if it’s faulty, contaminated, or when major A/C repairs are carried out—especially after compressor failure or when the system’s been left open to atmosphere.
