Product Details

The Four Seasons A/C expansion valve (also called a thermal expansion valve, TXV, or A/C metering device) controls how much liquid refrigerant enters the evaporator in your vehicle's air conditioning system. By regulating refrigerant flow, it helps the system cool efficiently and keeps the evaporator from freezing or starving.

Key Features:

  • Meters refrigerant into the evaporator to match cooling demand
  • Helps maintain consistent vent temperatures and A/C performance
  • Designed as a replacement for the original component in the A/C refrigerant circuit
  • Made by Four Seasons, a long-established supplier of aftermarket A/C and engine cooling parts
  • Each part number in this line is built for a specific application

Why Replace It: A failing expansion valve can cause weak cooling, warm air at the vents, uneven or fluctuating temperatures, or a frosted evaporator. Replacing it restores proper refrigerant metering and A/C performance.

Installation Notes: The A/C system should be properly evacuated and recharged after installation. Replacing the receiver/drier or accumulator at the same time, and using new O-rings or seals, is a common practice that helps protect the repair.
