Product Details

The Four Seasons Expansion Valve line focuses on precise refrigerant metering for automotive HVAC systems. This 39033 valve is configured for R134A service and uses female insert O-ring connections at the liquid and suction ports for a secure seal in the A/C circuit. For 2005-2006 Hyundai Elantra models, it supports proper refrigerant expansion at the evaporator, helping the system maintain consistent outlet temperatures and balanced cooling performance. This part cross-references UAC EX10256C for the same application.

Common A/C Problems This Part Can Address

• Warm air from the vents caused by restricted refrigerant control
• Uneven cabin cooling during A/C operation
• Incorrect evaporator refrigerant metering
• Loss of cooling performance in an R134A system
• A/C cycling issues related to a worn expansion valve

Installation Notes and Tips

Verify the vehicle uses the correct R134A block-type expansion valve configuration before installation. Inspect the mating surfaces, O-ring condition, and line cleanliness before assembly, and replace damaged seals as needed with the correct refrigerant-compatible components. Confirm the liquid and suction port sizes match the original HVAC layout on the Hyundai Elantra before recharging the system.
