Expansion Valve Overview

The expansion valve meters refrigerant into the evaporator; a stuck valve causes poor cooling or icing. Van Horn Truck Parts carries A/C expansion valves cross-referenced to OEM part numbers.

Match by your make, model, and A/C system, and the valve type.

Mechanic & Fitment Specs:

  • Match by: Make/model, A/C system, valve type
  • Cross-references: OEM
  • Buying tip: Replace the drier/accumulator with the expansion valve
