Four Seasons 39141 Expansion Valve Overview
The Four Seasons 39141 expansion valve is a block-type A/C flow restrictor built for R134A systems. It uses an aluminum body with captured O-ring connections and a 4.000 super heat setting for controlled refrigerant metering in the HVAC circuit.
Compatible with 2004-2005 Toyota Echo expansion valve applications, this Four Seasons Expansion Valve line part is a direct-fit service component for restoring proper A/C refrigerant flow. The 39141 part number is also referenced in aftermarket interchange listings for the same application.
Key Features
- Block-type A/C expansion valve for R134A refrigerant systems
- Aluminum construction with aluminum finish
- Captured O-ring inlet and outlet connections
- Female suction and liquid fittings with non-threaded interfaces
- 2 mounting holes for OE-style installation points
- 4.000 super heat specification
- Meets or exceeds OEM requirements
- Style: w/o solenoid
Product Details
Four Seasons 39141 is part of the Expansion Valve product line and is engineered for HVAC systems that require precise refrigerant control at the evaporator inlet. The liquid inlet and outlet use captured O-ring sealing surfaces, while the suction side uses female No. 12 fittings with non-threaded connections. This configuration supports service replacement on vehicles that use the specified OE-style block valve layout. The 39141 expansion valve is listed for 2004-2005 Toyota Echo models and is a practical choice when diagnosing poor cooling performance tied to refrigerant metering.
Common A/C Problems This Part Addresses
- Warm air from the vents caused by restricted refrigerant flow
- Erratic evaporator performance from a sticking expansion valve
- Uneven cabin cooling related to incorrect superheat control
- Loss of A/C efficiency after HVAC service or component replacement
- Refrigerant metering issues in R134A systems on Toyota Echo applications
Installation Notes and Tips
Verify the vehicle uses the listed block-type valve layout, R134A refrigerant, and matching suction and liquid fitting sizes before installation. Inspect the sealing surfaces and replace damaged O-rings during service to maintain proper sealing at the captured O-ring connections. Confirm the system is clean and evacuated before recharging, and follow the vehicle service procedure for the 2004-2005 Toyota Echo.
Quality Assurance
Four Seasons 39141 meets or exceeds OEM requirements and is built to match the specified application details for reliable HVAC service replacement.
