Detailed Description
Four Seasons 39097 is an OE-style A/C expansion valve designed for HVAC systems that use R134A refrigerant. The block-type design meters refrigerant into the evaporator based on system demand, helping the air conditioning system maintain consistent outlet temperatures. It uses female captured O-ring fittings on the suction and liquid sides, with aluminum construction for serviceable fit and corrosion resistance. This part number 39097 is listed for 2001-2004 Toyota RAV4 and 2005 Toyota RAV4 through 11/05, making it a focused replacement for the original valve in those vehicles.
This part cross-references Pioneer Automotive Industries 759097 for the same application.
What It Helps Address
- Weak or inconsistent A/C cooling
- Improper refrigerant metering at the evaporator
- Temperature swings from a sticking or restricted expansion valve
- System performance issues after A/C service or component replacement
- Fitment-specific replacement needs on Toyota RAV4 HVAC systems
Installation Notes and Tips
Verify the vehicle uses an R134A system and confirm the original valve style before installation. Inspect the mating surfaces, O-ring sealing areas, and refrigerant lines for wear or contamination before reassembly. Because this valve uses captured O-ring connections and specific inlet and outlet sizes, matching the original configuration is important for proper sealing and refrigerant control. For Toyota RAV4 service, confirm whether the vehicle is a 2005 model built before or after 11/05.
Quality Assurance
Four Seasons lists this expansion valve as meeting or exceeding OEM requirements. The part is built as a replacement for select Toyota RAV4 applications and follows the specified OE-style fitment and connection design.
