Parts for your 2013 Mitsubishi Lancer-Tx valve

2013 Mitsubishi Lancer TX valve — what it does and when to service it

Technical sources confirm the 2013 Mitsubishi Lancer uses a TX valve (thermostatic expansion valve) in its air‑conditioning system. The Mitsubishi Lancer Workshop Manual (Heating & Air Conditioning, Group 55A) lists an “Expansion Valve” at the evaporator, and Mitsubishi’s parts catalogues (ASA/CAPS) show a genuine “Valve, Expansion” for CJ/CF Lancer models around MY2013 (market‑dependent part numbers commonly noted as 7815A047). Major OE suppliers and aftermarket catalogues for the same model year also specify a block‑type TXV rather than an orifice tube. So yes — a TX valve is fitted and relevant on the 2013 Lancer.

On this Lancer, the TX valve meters how much liquid refrigerant enters the evaporator, reacting to evaporator outlet temperature and pressure. That control keeps the evaporator from icing up and helps the cabin stay consistently cool without the compressor working overtime. It’s a compact block valve mounted at the evaporator inlet, typically accessed from the passenger side behind the glovebox area, with line connections passing through the firewall.

There’s no scheduled replacement for a TX valve — it’s a “fit and forget” component until symptoms pop up. Common signs of a crook TXV include weak cooling at idle, evaporator icing, wildly fluctuating vent temps, or odd hissing at the firewall. A specialist will usually confirm with gauge readings (e.g., low suction with normal/high discharge if the valve is stuck or restricted) and temperature checks across the valve.

If replacement’s on the cards, best practice is to have a licensed air‑con technician recover the refrigerant (it’s R‑134a on this model), swap the valve and O‑rings, pressure‑test, evacuate, then recharge to the factory label specification. It’s smart to replace the receiver/drier or desiccant bag (often integrated with the condenser on modern Mitsubishis) whenever the system’s opened or after compressor damage. Keeping the cabin filter clean, the condenser free of debris, and running the air‑con regularly all help the TXV live a long, drama‑free life.

• Typical causes of TXV trouble: moisture/contamination, desiccant breakdown, compressor wear sending debris, or prolonged system exposure to air.
• Good workshop habits: new O‑rings lubricated with the correct oil, torque line fittings properly, evacuate thoroughly, and verify superheat/subcooling on recharge.
• Legal note (AU/NZ): refrigerant handling must be done by appropriately licensed technicians (e.g., ARCtick in Australia).

Does the 2013 Mitsubishi Lancer use a TX valve or an orifice tube?

It uses a TX valve. Mitsubishi documentation and parts listings for the CJ/CF Lancer specify a block‑type thermostatic expansion valve at the evaporator inlet.

Where is the TX valve located on a 2013 Lancer?

It’s mounted at the evaporator, typically accessed from the passenger side behind the glovebox area. The refrigerant lines connect through the firewall in the engine bay.

When should the TX valve be replaced on a 2013 Lancer?

Replace it only when it’s faulty or after contamination events (e.g., compressor failure). Symptoms include poor cooling, icing, or unstable pressures. Any TXV replacement should include new O‑rings, evacuation, correct recharge, and a fresh receiver/drier or desiccant bag as applicable.
