What refrigerant is used by Ford?

Ford's modern vehicles predominantly use refrigerant R-1234yf (HFO-1234yf) for their air-conditioning systems. Some older models or regional variants may still employ R-134a.

The question of what refrigerant Ford uses touches on regulatory changes, vehicle age, and regional variation. This report surveys current standards across Ford's lineup, explains the rationale behind the shift, and outlines what owners and technicians should know when servicing Ford A/C systems.

Current standard: R-1234yf across Ford's lineup

Ford introduced R-1234yf as the standard refrigerant for nearly all new vehicles during the 2010s to meet environmental rules. Compared with R-134a, R-1234yf has a substantially lower global warming potential and is supported by Ford's workshop manuals and factory tools. In practice, most 2013-era Ford models and newer in key markets use R-1234yf. There are still exceptions: very early 2010s models, special fleets, or regional imports may still be supplied with R-134a.

Why the shift matters

The move to R-1234yf reflects broader regulatory pressure to reduce greenhouse gas emissions from vehicle air conditioning. The refrigerant's low GWP (around 4) stands in stark contrast to R-134a's GWP of about 1,300, making it a central part of the auto industry's decarbonization efforts.

Key differences between the two refrigerants that service technicians consider

• Global warming potential: R-1234yf has a GWP near 4; R-134a around 1,300.


• Flammability: R-1234yf is mildly flammable (A2L); R-134a is non-flammable (A1).


• Lubricants: R-1234yf typically uses POE oil; R-134a commonly uses PAG or POE depending on the system.


• System design and labeling: Ford A/C systems are designed for a specific refrigerant; mixing or retrofitting requires complete service adaptation.

Understanding these differences helps ensure proper service and environmental compliance when maintaining Ford air conditioning systems.

Timeline and regional variations

Ford's transition timeline reflects global regulatory changes, with the majority of modern vehicles using 1234yf, while some older models and certain markets may rely on 134a in service or for older inventory.

Milestones in Ford's refrigerant strategy

Key milestones include the gradual adoption of R-1234yf in new models during the 2010s and alignment with regional regulations mandating lower-GWP refrigerants for new cars.

• 2010s: Ford begins phasing in R-1234yf on new models as part of a global fleet modernization.


• 2011–2014: EU and other regions push for 1234yf for new cars; Ford aligns production and servicing guidelines.


• Mid to late 2010s: Most new Ford vehicles use R-1234yf; R-134a remains on older inventory and some regional fleets.

These milestones illustrate the gradual but broad shift toward 1234yf across Ford's lineup.

Regional notes and servicing tips

Regional differences and practical considerations when servicing Ford A/C systems include label checks, tool compatibility, and refrigerant sourcing.

Practical servicing guidance

Before servicing a Ford A/C system, technicians should verify the exact refrigerant type required for the specific model-year and market. Always use the refrigerant specified by Ford for that vehicle and avoid mixing different refrigerants, which can damage the compressor and seals.

• Check the label on the A/C compressor or under-hood sticker to identify the refrigerant type required for your specific Ford model.


• Use service equipment and refrigerant that match Ford's specification; do not mix refrigerants in a system.


• If your vehicle uses 1234yf, use the appropriate 1234yf-compatible lubricant and equipment; for older 134a, use the corresponding lubricant and equipment.


• Retrofits from 1234yf to 134a or vice versa are not standard and require comprehensive system overhaul and component replacements.

When in doubt, consult a Ford service bulletin or a certified technician to confirm refrigerant type and safe handling requirements.

Summary

Ford's current standard refrigerant for most new vehicles is R-1234yf, aligning with global environmental regulations and market requirements. Some older models or regional variants may still use R-134a, especially in markets where older stock remains in circulation. Always verify the exact refrigerant type from the vehicle's label or Ford service documentation, and ensure service uses the correct refrigerant and lubricants to maintain performance and safety.

What type of refrigerant does Ford use?

Ford uses both R-134a and R-1234yf refrigerants, with R-134a used in most models prior to 2017 and R-1234yf in many newer models, particularly those manufactured after 2017. The correct type of refrigerant depends on the specific vehicle's model year and system, so it is essential to check the vehicle's label or owner's manual to confirm the exact type needed. 

• R-134a: This was the standard refrigerant for many Ford vehicles for years. You can often find it specified with a Ford part number like YN-19. 
• R-1234yf: This is a newer, more environmentally friendly refrigerant that has been phased in for use in many newer models, starting around 2017. 
• How to check: The most reliable way to know which refrigerant your vehicle uses is to look for a sticker or label under the hood or in the owner's manual. It will specify the correct refrigerant type and capacity. 

Can I replace 1234YF with 134a?

No, you should not use R134a in an R1234yf system because the refrigerants are chemically different, have different pressures and oil requirements, and the service ports have different fittings. Using the wrong refrigerant can damage the AC system and its components, and it may be a violation of regulations. While some have reportedly performed a conversion by fully evacuating the system and using an adapter, this is not recommended by professionals due to the risk of system damage and legal issues. 
Reasons to avoid using R134a in an R1234yf system

• Different fittings: R1234yf systems have unique service ports and hose connections to prevent the use of older refrigerants like R134a, which have smaller fittings. 
• Chemical incompatibility: The refrigerants are chemically different and are not meant to be mixed. Mixing them can lead to system contamination and failure. 
• Oil incompatibility: R1234yf systems require specific oils (like POE), while R134a systems typically use PAG oil. The two are not compatible and mixing them can damage the compressor. 
• Pressure differences: The systems are designed to operate at different pressures. Using R134a in an R1234yf system can cause excessive pressure and damage components. 
• Reduced performance: Even if the system doesn't immediately fail, performance is likely to be inefficient, and the system may encounter issues like evaporator freezing. 
• Legal and warranty issues: Tampering with an emissions-controlled device by using the wrong refrigerant is a violation of the Clean Air Act. This could also void your vehicle's warranty.

What to do instead

• Always use the refrigerant specified on the vehicle's under-hood label. 
• If your AC system is low on refrigerant, it means there is a leak that needs to be professionally diagnosed and repaired before recharging the system with the correct refrigerant. 

How do I know if my AC is 410A or R22?

Device such as this one right. Here that's an R22 thermostatic expansion valve. And here's an R410A thermostatic expansion valve. But now not only do you have to determine if it's R22 or R410A.

Can I still get R12 refrigerant for my car?

R12 refrigerant is phased out due to environmental regulations, making it scarce. For vintage AC systems, seek certified suppliers or specialty shops offering reclaimed R12 or approved substitutes like R12a. Always check system seals, hoses, and compressor condition before recharge to prevent leaks.
