Four Seasons 39486 A/C Expansion Valve Rear TXV for Freightliner

The Four Seasons 39486 is a replacement rear A/C expansion valve (TXV — thermostatic expansion valve) engineered for Freightliner heavy-duty trucks, including the Century Class, Columbia, and Coronado models. It restores proper refrigerant flow regulation to the air conditioning evaporator, helping return the system to factory cooling performance.

The thermostatic expansion valve meters refrigerant entering the evaporator based on system demand. Each TXV is built to a unique specification for tonnage, superheat, and maximum operating pressure (MOP) to match the requirements of the specific A/C system it serves. Using an incorrect or low-quality valve is a leading cause of A/C performance issues in heavy-duty trucks, making an exact-fit replacement critical.

Key Features:

• Direct-fit replacement thermostatic expansion valve (TXV)
• Precision-machined ports for accurate refrigerant metering
• Calibrated to OEM tonnage, superheat, and MOP specifications
• Designed for rear A/C system position on applicable Freightliner trucks
• Manufactured by Four Seasons, one of the industry's largest aftermarket mobile climate control suppliers
