4th Gen Ram A/C Expansion Valve Kit (12-18) – 68138269AB

Your A/C is blowing warm — or cooling inconsistently even with a full refrigerant charge. On 4th Gen Ram trucks, a failed expansion valve restricts refrigerant flow into the evaporator, causing weak or no cooling. This is the OEM Mopar replacement kit, built to factory spec.

Part Number: 68138269AB

Fits:

• 2012 Ram 1500 (3.7L V6, 4.7L V8, 5.7L V8)
• 2012–2018 Ram 2500 (5.7L V8, 6.4L V8, 6.7L Diesel)
• 2012–2018 Ram 3500 (5.7L V8, 6.4L V8, 6.7L Diesel)

⚠️ Fitment note: The 2009–2013 Ram 1500/2500/3500 uses a different expansion valve (68048896AB). Confirm your model year before ordering.

Why replace it?

• A/C blows warm or inconsistently cool with a full refrigerant charge
• Evaporator freezing up (over-restriction of refrigerant flow)
• A/C system pressure readings out of spec
• Refrigerant charge not holding after confirmed leak repair

What the expansion valve does:
The expansion valve meters refrigerant flow into the evaporator core. Too little flow and the A/C won’t cool. Too much and the evaporator freezes. A failed valve disrupts this balance — replacing it restores proper refrigerant metering and full A/C performance.
