Product Details

Four Seasons 39052 is part of the Expansion Valve line and is engineered to regulate refrigerant flow into the evaporator in rear air conditioning circuits.

Installation Notes and Tips

Verify the vehicle uses an R134A rear HVAC setup before installation. Match the block-type valve, port sizes, and insert O-ring connection style to the original component on the 2003-2006 Dodge Durango, rear. Replace worn O-rings and inspect mating surfaces for contamination or damage before reassembly. Proper evacuation and recharge procedures are important after any A/C component replacement.
