Product Details

The Four Seasons 37490 is a replacement A/C expansion valve designed for select Lexus and Toyota vehicles. This expansion valve is a critical component of the air conditioning system, regulating the flow of refrigerant into the evaporator to maintain optimal cooling performance.

Key Features:

  • Direct-fit replacement expansion valve for OEM specifications
  • Precision-engineered to regulate refrigerant flow and pressure
  • Designed to restore proper A/C system operation and cooling efficiency
  • Manufactured by Four Seasons, a trusted name in automotive climate control components

This expansion valve is application-specific for certain Lexus ES300, RX300, and Toyota Avalon, Highlander, and Sienna model years. Replacing a faulty expansion valve can resolve issues such as inadequate cooling, icing on A/C lines, or inconsistent air conditioning performance.
