Parts for your 2007 Ford Escape-Tx valve

2007 Ford Escape TX valve — is it actually used on this model?

Short answer: for most 2007 Ford Escape models, a TX (thermostatic expansion) valve isn’t used. The factory A/C design on the petrol (non-hybrid) 2007 Escape is the Ford CCOT system — Cycling Clutch Orifice Tube — which meters refrigerant with a fixed orifice tube and uses an accumulator, not a TX valve. Technical references that state this include the Ford Workshop Manual for 2007 Escape (Section 412-03 Climate Control), which describes a fixed-orifice/accumulator layout, and the Motorcraft/Ford parts catalogue listings that show an A/C orifice tube and accumulator for 2007 Escape petrol models, while not listing an expansion valve for those variants. By contrast, the 2007 Escape Hybrid uses a different A/C strategy and is fitted with an expansion (TX) valve at the evaporator.

Why didn’t Ford use a TX valve on the petrol 2007 Escape? The CCOT setup was chosen across many Fords of that era because it’s robust, simple, and cost-effective. A fixed orifice tube meters refrigerant at a constant size, and system capacity is regulated by cycling the compressor clutch and storing refrigerant in the accumulator. That suits steady, belt-driven compressors and delivers reliable cooling without the extra moving parts and sensing element a TX valve brings. The upshot is fewer failure points and straightforward servicing when the vehicle is used in typical Australian and New Zealand conditions.

What does this mean for servicing? On a 2007 Escape petrol model, attention should go to the actual metering and protection components fitted from the factory:

• Orifice tube (in the liquid line) — can clog with debris, replace if there’s compressor damage or contamination.
• Accumulator/drier — replace whenever the system is opened to atmosphere or after a compressor failure.
• System flushing, correct oil type/quantity, evacuation, and a precise R-134a charge are essential to prevent repeat issues.

Note for 2007 Escape Hybrid owners: the hybrid uses a TX valve and an electric A/C compressor, it requires manufacturer-specified oil and high-voltage safety procedures during service. The Ford Workshop Manual and Ford parts catalogues identify the TX valve for the Hybrid variant only.

FAQs

Does my 2007 Ford Escape have a TX valve?
Most petrol (non-hybrid) 2007 Escapes do not, they use a fixed orifice tube with an accumulator (CCOT). The 2007 Escape Hybrid does use a TX valve at the evaporator. Checking the VIN against the Ford parts catalogue or viewing the liquid line for an orifice-tube service joint is a quick way to confirm.

Where is the metering device on a 2007 Escape, and what should be serviced?
On petrol models, the metering device is a fixed orifice tube usually located in the liquid line near the condenser-to-evaporator path, with an accumulator on the low side. Replace the orifice tube and accumulator if the system’s been contaminated or the compressor has failed. For the Hybrid, the TX valve is at the evaporator inlet and may be replaced if stuck or contaminated, observing Hybrid-specific procedures and oil.

What are the symptoms of a blocked metering device on a 2007 Escape?
Warm air at the vents, rapid compressor clutch cycling, low suction pressure with unusually high high-side pressure, and frost forming on the liquid line are common signs. On petrol models this often points to a clogged orifice tube, on Hybrids it may indicate a sticking TX valve. Proper diagnosis with gauges and temperature checks is recommended before parts replacement.
