The 2014 Chevrolet Silverado uses R-134a refrigerant in its air-conditioning system.
In detail, this year’s Silverado is designed around R-134a refrigerant with PAG oil. It does not use the newer R-1234yf refrigerant that appears in some later GM models. If you’re servicing the system, follow the OEM specs for refrigerant type, oil, and recovery/recharge procedures. Do not mix refrigerants, and seek professional help if you’re unsure about the process or handling of refrigerants.
Refrigerant used in the Silverado and what it means
Below are the essential facts about the refrigerant used in the 2014 Silverado and how that affects maintenance and service.
- Refrigerant type: R-134a (HFC-134a).
- Lubricant: PAG oil is used with R-134a, commonly PAG-46 for many GM systems.
- System capacity: typical charge is about 1.8 pounds (roughly 0.8 kilograms) of R-134a for a standard Silverado A/C system.
- Service ports: standard high- and low-pressure service ports; use a proper manifold gauge set for diagnosis and charging.
- Label guidance: check under-hood labels or the vehicle’s service manual for exact spec and procedure details.
These points summarize the refrigerant and oil requirements, plus basic service considerations for the 2014 Silverado’s A/C system.
Service considerations and practical steps
To service an R-134a system in the Silverado, follow these general steps and safety notes.
- Recover refrigerant with EPA-approved equipment before opening the system.
- Evacuate the system to a deep vacuum (typically 500 microns or better) to remove moisture and air.
- Inspect for leaks and replace components such as the receiver/drier or accumulator if needed.
- Recharge with the correct amount of R-134a (about 1.8 pounds) and add PAG-46 oil as specified by the service manual.
- Test the system’s pressures and cooling performance across normal operating temperatures.
In practice, using the right refrigerant and oil, plus proper recovery and vacuum procedures, helps ensure reliable cooling and long-term system health.
Is R-1234yf ever used in this model?
For the 2014 Silverado, R-134a is the standard refrigerant. R-1234yf is not typical for this model year. Retrofitting to 1234yf, if even possible, would require a full approved retrofit with compatible hardware and oil, and should be evaluated by a qualified technician with GM specifications in mind.
Summary
The 2014 Chevy Silverado’s air-conditioning system relies on R-134a refrigerant with PAG oil, with a typical charge near 1.8 pounds. Always use the correct refrigerant type, follow proper recovery and evacuation steps, and consult the service manual or a professional technician for precise procedures and specifications.

What's the worst year for Chevy Silverado 1500?
Worst Years for the Chevy Silverado 1500
- 2007–2011 (early GMT900) – Known for AFM oil use, lifter noise, and costly engine repairs.
- 2014–2016 (early K2XX) – Frequent A/C condenser leaks, transmission shudder, and cabin vibration.

Does my car use R-134a or R1234yf?
Cars built mid-1990s to roughly 2014–2017 almost always use R134a. Most 2017–present vehicles, especially Euro, hybrid and EV models, use R-1234yf. Some EVs use specialised refrigerant blends depending on the cooling system. Your car has a sticker under the bonnet that confirms its exact gas type.
