Product Details

This Four Seasons expansion valve is built for 1981-1988 Toyota Cressida HVAC service and is listed as an A/C expansion valve for the system’s refrigerant metering circuit. The brass body and TXV design support controlled refrigerant delivery to the evaporator, helping the A/C system maintain consistent cooling performance. If you are servicing a Toyota Cressida with R134A conversion or R134A-based operation, Four Seasons 38629 provides a fitment-specific replacement option. This part cross-references Monroe Shocks & Struts (e.g., 182207) for the same application.

Common Issues This Part May Address

• Inconsistent cabin cooling on a Toyota Cressida
• Improper refrigerant metering at the evaporator
• Incorrect superheat control in the A/C circuit
• Restricted or unstable refrigerant flow through the HVAC system
• Loss of cooling performance during A/C operation

Installation Notes and Tips

Verify the vehicle’s refrigerant type and system configuration before installation. Replace the expansion valve during A/C service when diagnosing flow restriction, evaporator performance issues, or superheat concerns. Confirm all sealing surfaces are clean and that the replacement valve matches the application requirements for 1981-1988 Toyota Cressida models.
