Parts for your 2015 Ford Focus-Tx valve

2015 Ford Focus TX valve — is it even there?

Short answer: a thermostatic expansion valve (TX valve) is not used on the 2015 Ford Focus. Ford’s own technical literature points that way. The Ford Workshop Manual for the 2015 Focus (Climate Control, Section 412-01) specifies a fixed orifice tube—listed as the A/C evaporator core orifice, part code 19D990—as the metering device in the liquid line at the evaporator inlet. Likewise, Motorcraft parts catalogues for the 2012–2018 Focus family list an A/C refrigerant orifice tube but no expansion valve for this platform.

Why no TX valve? Ford engineered this generation Focus with a variable-displacement compressor and a fixed orifice tube. Instead of a TX valve trimming refrigerant flow at the evaporator, the compressor’s swashplate regulates output based on demand. It’s a proven combo that keeps costs down, packaging tight, and performance consistent for everyday Aussie and Kiwi driving. The condenser carries an integrated desiccant (receiver/drier function), and the metering is handled by that simple fixed orifice—no separate TX valve body is fitted.

So if someone is chasing a “2015 Ford Focus TX valve”, they’re looking for a part the car doesn’t have. The correct metering part is the orifice tube, typically located in the liquid line heading into the evaporator at the bulkhead in the engine bay. When the A/C system is opened for major work—like a compressor replacement—best practice is to replace the orifice tube and renew the condenser desiccant, then evacuate and recharge to spec with the right oil balance. That’s the sort of servicing that keeps cabin temps frosty without any dramas.

Common symptoms that make people suspect a TX valve on these cars are usually tied to a clogged orifice tube or compressor wear. Think weak cooling at idle, uneven vent temps, or pressure readings that show a starved evaporator. On a Focus, sort the orifice tube and system cleanliness first—there’s no TX valve to adjust or replace.

• Metering device fitted: Fixed orifice tube (A/C evaporator core orifice, 19D990)
• No TX valve on this model/year
• Compressor type: Variable displacement, PCM-controlled
• Good practice: Replace orifice tube and refresh desiccant when the system is opened

Popular questions about a 2015 Ford Focus TX valve

Does the 2015 Ford Focus have a TX valve?
No. The 2015 Focus uses a fixed orifice tube as the refrigerant metering device. Ford’s workshop documentation and Motorcraft parts listings show an orifice tube and do not list a TX valve for this model.

What does the 2015 Focus use instead of a TX valve?
It uses a fixed orifice tube paired with a variable‑displacement compressor. The compressor output is modulated to control cooling, while the orifice tube provides a constant restriction at the evaporator inlet.

Can a TX valve be retrofitted to a 2015 Focus?
It’s not recommended. The system design, controls, and plumbing are built around a fixed orifice tube and variable‑displacement compressor. Retrofitting a TX valve would require extensive re-engineering and offers no practical benefit for reliability or performance.
