2025 Mitsubishi Eclipse Cross TX Valve

Yes, the 2025 Mitsubishi Eclipse Cross uses a thermal expansion valve (TX valve) in its air-conditioning system. Technical sources point to this: the Mitsubishi Motors Eclipse Cross Service Manual (Heating and Air Conditioning/Group 55A) depicts an expansion valve at the evaporator inlet, the Mitsubishi ASA electronic parts catalogue for GK/GL series lists a “Valve, Expansion” in the A/C group, and DENSO’s automotive A/C fundamentals explain the TXV arrangement used with variable-displacement compressors commonly fitted to modern Mitsubishis.

The TX valve meters refrigerant into the evaporator based on superheat, keeping the evaporator cold without letting it ice up. On the 2025 Eclipse Cross, that means steady cabin temps, decent demist performance, and efficient compressor load. Many markets run R‑1234yf refrigerant by this model year, owners should check the under‑bonnet label for the exact spec and charge.

TX valves aren’t a routine service item, but they can wear or clog. Typical signs of a crook valve include weak cooling at idle, vent temperatures that swing hot‑cold, evaporator icing, odd hissing, and mismatched high/low gauge pressures.

• Replace the valve if it’s stuck (open or closed), leaking at the body or fittings, or contaminated after a compressor failure.
• Always fit new OE‑spec O‑rings, observe correct torque, and keep everything surgically clean to avoid moisture and debris ingress.

Replacement lives at the evaporator connection inside or at the firewall area, so trim removal may be required. In Australia and New Zealand, refrigerant work must be carried out by an ARCtick‑licensed technician. The right process is to recover the gas, isolate and remove the valve, renew O‑rings, pressure‑test with dry nitrogen, evacuate to deep vacuum, then weigh in the exact charge shown on the vehicle label. If the system’s been open, the receiver‑dryer desiccant should be renewed and the correct amount of compressor oil balanced. A fresh cabin filter and a clean condenser face help overall A/C performance too.

Whether petrol or PHEV, the Eclipse Cross platform keeps the same TXV function. With proper handling and clean refrigerant, the valve should last many years while delivering crisp, reliable cooling in Aussie and Kiwi conditions.

Popular questions about a 2025 Mitsubishi Eclipse Cross TX valve

Does the 2025 Eclipse Cross use a TX valve or an orifice tube?
The 2025 model uses a thermal expansion valve at the evaporator inlet, not a fixed orifice tube. This setup suits the variable‑displacement compressor and gives finer control of superheat for stable vent temperatures and better efficiency.

When should the TX valve be replaced?
There’s no fixed interval. It’s replaced when there are symptoms like poor cooling, icing, or erratic pressures, or whenever the system has suffered compressor failure or heavy contamination. A licensed A/C technician can confirm diagnosis with temperature and pressure readings.

How long does replacement take and what else should be done?
Workshop time varies by trim access and test steps, but a few hours is typical including recovery, vacuum, and recharge. It’s smart to renew O‑rings, check the receiver‑dryer desiccant, and confirm the correct refrigerant weight with a calibrated scale.
