Parts for your 2016 Ford Focus-Tx valve

2016 Ford Focus TX valve — is it a thing?

Short answer: a TX valve isn’t used on the 2016 Ford Focus. Referencing the Ford Workshop Manual (WSM) for 2015–2018 Focus models (Section 412-00, Climate Control), the metering device shown and serviced is a fixed orifice tube, not a thermostatic expansion valve. Motorcraft/Ford parts catalogues list the orifice tube under group 19 (commonly 19D990) for this model, with no expansion valve listed. Trade service databases (e.g., Mitchell 1, ALLDATA) describe the Focus A/C as an orifice-tube system with a receiver–drier integrated in the condenser and a variable-displacement compressor.

Why doesn’t the 2016 Focus run a TX valve? Ford engineered this platform around a fixed orifice tube (FOT) and a variable-displacement compressor. In this setup, the compressor modulates output based on pressure sensor feedback, while the orifice tube provides a steady restriction. It’s a robust, cost-effective design with fewer moving parts than a TX valve, and it suits the Focus’s control strategy nicely. With no TX valve to stick or drift, there’s one less precision component to worry about under the bonnet.

If chasing weak A/C on a 2016 Focus, the attention points aren’t a TX valve. Instead, think about:

• Orifice tube clogging from compressor wear debris.
• Low refrigerant charge or small leaks (condenser stone strikes are common).
• Receiver–drier desiccant saturation (the drier is built into the condenser on many Focus variants).
• Condenser airflow issues (bent fins, fans not kicking in).

Technically minded owners will find the orifice tube located in the liquid line at the evaporator inlet or line joint near the condenser/evaporator feed, depending on build. Replacement requires refrigerant recovery, O-ring renewal, correct oil balance, and an accurate recharge by weight. If the compressor has failed, plan on replacing the condenser (to renew the drier), flushing lines, and fitting a new orifice tube to keep the system clean and reliable.

So, while “2016 Ford Focus TX valve” is a popular search, the right part to service is the fixed orifice tube and associated components. Keep the charge spot-on, ensure clean airflow through the condenser, and the Focus’s A/C will blow cold even on a harsh Aussie or Kiwi summer’s day.

• Does a 2016 Ford Focus have a TX valve?
  No. It uses a fixed orifice tube with a variable-displacement compressor, as documented in the Ford Workshop Manual and Motorcraft parts listings.
• What does the job of a TX valve on this car?
  The fixed orifice tube meters refrigerant flow, while the compressor modulates capacity. Together, they achieve the same outcome a TX valve would in other systems.
• Can a TX valve be retrofitted?
  It’s not practical. Retrofitting would mean redesigning lines, controls, and possibly the compressor strategy. It’s far easier and more reliable to service the stock orifice-tube system properly.

Popular questions about a 2016 Ford Focus TX valve

Does my 2016 Ford Focus have a TX valve?
No. The 2016 Focus uses a fixed orifice tube instead of a thermostatic expansion valve. Ford’s service literature and OE parts catalogues show the orifice tube as the metering device for this model.

What part replaces the TX valve’s role, and where is it?
The fixed orifice tube meters refrigerant flow. It’s typically located in the liquid line near the evaporator inlet or a line joint by the condenser/evaporator feed. Access requires recovering refrigerant and separating the line to extract the small insert.

Should I try to retrofit a TX valve for better cooling?
Not recommended. The Focus’s A/C strategy relies on the fixed orifice tube and a variable-displacement compressor. Retrofitting a TX valve would involve significant changes and won’t deliver reliable gains compared with maintaining the original system.
