What freon does a 2015 F350 take?
The 2015 Ford F-350 uses R-134a refrigerant (often referred to as Freon) for its air-conditioning system. This model year does not factory-use the newer R-1234yf refrigerant. When servicing the A/C, use R-134a with the correct lubricant specified for this system.
Identifying the correct refrigerant for your F-350
To confirm the exact refrigerant type and oil requirements, check the under-hood A/C service label and the owner's manual or a Ford service bulletin. The standard configuration for a 2015 F-350 is R-134a, and R-1234yf is not used in the usual factory setup for this year.
- Common refrigerant: R-134a (HFC-134a).
- Oil compatibility: PAG oil is typically used with R-134a; the exact grade (commonly PAG-46) and the amount depend on the system and should follow Ford’s specifications.
- R-12 and R-1234yf: R-12 is obsolete in modern vehicles; R-1234yf is used on some newer models, but not the standard configuration for the 2015 F-350.
Always verify with the vehicle’s service label under the hood or the official Ford documentation before purchasing refrigerant or oil.
Steps to service the A/C system correctly
When servicing the A/C, follow these steps to ensure proper operation and avoid damage to the compressor or hoses.
- Confirm refrigerant type on the under-hood label or owner's manual: R-134a for the 2015 F-350.
- Evacuate the system to remove moisture and any old oil.
- Vacuum and hold the vacuum for the recommended duration to ensure all moisture is removed.
- Recharge with the correct amount of R-134a as specified by the service label, which may vary by configuration.
- Add the appropriate PAG oil if the system was opened or drained of oil; follow the exact quantity and grade specified by Ford.
- Perform a leak test and monitor pressures after recharge to ensure there are no leaks in the condenser, hoses, or compressor.
After completing these steps, run the A/C to verify cooling performance and check for any unusual noises or abnormal pressures.
Notes for technicians and retrofits
If a retrofit to a different refrigerant is being considered, such as moving to R-1234yf, be aware that this requires specific hardware, oils, and procedure changes. Do not swap refrigerants without confirming compatibility on the service label and consulting Ford’s technical resources.
Summary
The 2015 Ford F-350 is designed to use R-134a refrigerant with PAG oil. Verify the exact charge and oil specifications from the under-hood service label or Ford documentation, evacuate and recharge properly, and perform a leak test after service. If unsure, consult a certified HVAC technician or Ford dealer to ensure proper operation and avoid warranty issues.
