• Expansion valve restriction or internal wear
• Uneven A/C performance after system service
• Loss of cooling efficiency in R134A systems

Installation Notes and Tips

Verify the vehicle’s refrigerant type, port style, and fitment before installation. This valve uses captured O-ring sealing surfaces, so inspect the mating surfaces and replace damaged seals during service. Confirm the application by year, make, and model, especially on 2011-2014 Toyota RAV4 Japan-built vehicles and 2012 Toyota Matrix units built to 8/11. Proper evacuation, leak checking, and recharge procedures are required after A/C component replacement.
