The aluminum body and validated internal finish support consistent refrigerant metering and sealing performance.

What It Is Used For

• Restoring weak or inconsistent cabin cooling
• Correcting refrigerant metering issues at the evaporator
• Addressing A/C performance loss caused by a restricted or worn valve
• Resolving leaks at the expansion valve connection points
• Replacing a failed OE-style valve during HVAC service

Installation Notes and Tips

Install the valve on the confirmed vehicle application only: Fits 2024-2025 Toyota Corolla, N/A; Fits 2024-2025 Toyota Corolla Cross, N/A; Fits 2018-2019 Lexus RX350, front, exc. Japan built; Fits 2018-2019 Lexus RX350L, front, exc. Japan built. Replace the O-rings during service, verify the refrigerant type is R134, and evacuate and recharge the system according to factory procedures after installation. Confirm the front-position Lexus fitment and Japan-built exclusion before ordering.

Quality Assurance

Nissens manufactures thermal expansion valves to OE-matching standards and tests pressure performance, tightness, opening characteristics, set-point calibration, and internal finish for consistent HVAC operation. The 9991015 is built to the same control standards used across Nissens expansion valve production.
