Four Seasons 39438 a/c expansion valve for the 2012-2018 Ram 2500 and other vehicles is a block type valve without a solenoid; it controls refrigerant flow into the evaporator.
- Engineered and tested for trouble-free operation, backed by over 50 years of mobile a/c experience
- Calibrated for cabin comfort for both the driver and passengers
- Meets or exceeds O.E. fit, form and function requirements
- Precision machined ports
Weak or uneven cooling, or frost at the valve, can mean the expansion valve is failing, but low refrigerant or a compressor problem can look the same. Before replacing it, look over the A/C lines and fittings with the engine off for oily residue or damage, and leave pressure testing to a shop with gauges.
Its fitment also includes the 2012 Ram 1500 and the 2012-2018 Ram 3500, and a vehicle takes one valve.
