Product Details

This Four Seasons expansion valve regulates refrigerant flow into the evaporator to help maintain proper A/C performance and temperature control. The TXV design responds to system demand, making it a practical replacement for vehicles that need accurate refrigerant metering in R134A-equipped HVAC systems. Four Seasons 38844 is listed across a wide range of Chrysler, Dodge, and Plymouth factory-air applications, including 1965-1973 Chrysler Imperial, New Yorker, Newport, and 300; 1965-1973 Dodge Monaco and Charger; and later Dodge B-series and Ramcharger platforms.

This part cross-references Monroe Shocks & Struts 182116 for the same application.

What It Helps Address

  • Inconsistent cabin cooling from a worn or restricted expansion valve
  • Improper refrigerant metering in an R134A A/C system
  • Evaporator performance issues caused by TXV wear
  • Temperature fluctuation in factory-air HVAC systems
  • A/C service needs on classic Dodge, Chrysler, and Plymouth vehicles

Installation Notes and Tips

  • Verify the vehicle uses an R134A system before installation.
  • Confirm the correct valve style and position, including rear or front application where listed.
  • Match the existing HVAC layout and factory-air configuration to the fitment notes.
  • Inspect the system for contamination or restriction before replacing the valve.
  • Use the vehicle-specific fitment data for Dodge B150, B250, B350, Plymouth PB150, PB250, PB350, and related Chrysler/Dodge models.

Quality Assurance

Four Seasons 38844 is built as an HVAC flow restrictor component for specified factory-air applications and is identified by OE-style interchange references for service matching. Confirm fitment against the vehicle year, make, model, and A/C configuration before ordering.
