Parts for your 2013 Toyota Land cruiser-Tx valve

2013 Toyota Land Cruiser TX valve (thermal expansion valve)

Based on Toyota’s 200 Series Repair Manual (air conditioning section), DENSO system literature, and Toyota Genuine Parts catalogues for the URJ202-platform sold in Australia and New Zealand, the 2013 Toyota Land Cruiser uses an air-con expansion valve (TX valve/TXV). Vehicles with rear air conditioning are fitted with two TX valves—one for the front evaporator and one for the rear—so a 2013 Land Cruiser absolutely has a txvalve and it’s a relevant service item.

The TX valve is the metering brain of the Land Cruiser’s A/C. It regulates how much liquid refrigerant enters the evaporator, responding to temperature and pressure so the system hits that sweet spot of cool, dry air without icing up. In the 200 Series, a healthy TXV helps keep vent temps stable while you’re towing up the Kaimais or crawling a rutted track in the High Country.

When should owners think about the txvalve? It’s not a routine replacement like a cabin filter, but it should be assessed any time the system’s open, during compressor swaps, or if cooling performance is flaky. Signs it’s playing up include erratic cabin temps, icing on the evaporator or lines, a noticeable hiss near the valve area, or pressure readings that don’t match spec on high/low sides. On dual A/C models, poor rear cooling with decent front cooling can point to the rear TXV in particular.

• Service tips for the 2013 Land Cruiser txvalve:
  • Always replace the receiver/drier or desiccant bag when the system is opened.
  • Use the correct PAG oil type and quantity, account for component replacement oil balancing.
  • Fit new OE-quality O-rings, lightly lubricated with compatible oil.
  • Pull a proper vacuum and weigh in the R134a charge to factory spec—no guessing.
  • On dual A/C models, inspect both front and rear TXVs if symptoms suggest uneven cooling.

Location-wise, the front TXV sits at the front evaporator (in or near the HVAC case at the firewall area), while the rear TXV is mounted at the rear evaporator behind interior trim in the cargo area on dual A/C vehicles. Replacement is straightforward for an experienced tech but can be trim- and dash-intensive, so budgeting labour makes sense. After refit, a leak check, vacuum, and precise recharge are non-negotiable. Done right, the 2013 Land Cruiser’s air-con will stay frosty on the hottest Aussie or Kiwi summer days.

Popular questions about the 2013 Toyota Land Cruiser txvalve

Where is the TX valve on a 2013 Land Cruiser?

The front TXV is mounted at the front evaporator inside or at the HVAC case near the firewall. If the vehicle has rear air-con, a second TXV sits at the rear evaporator behind the side trim in the cargo area.

What are common symptoms of a faulty TX valve on a 200 Series?

Expect inconsistent vent temps, poor cooling at idle, icing or sweating on lines, and high/low-side gauge readings out of spec. On dual A/C models, good front cooling but weak rear cooling can point to the rear TXV.

Should the TX valve be replaced when the compressor is changed?

It’s wise to inspect or replace the TXV when a compressor fails, particularly after an internal failure that may send debris through the system. Always replace the receiver/drier, flush where appropriate, and recharge to spec.
