2019 Ford Transit A/C Refrigerant & Oil Capacity

Quick Answer

• Refrigerant Type: R-1234yf
• Full System Charge: 22.9 oz (650 grams)
• PAG Oil Type: PAG 46
• PAG Oil Amount: 6.0 oz (180 mL) for single A/C system; 8.1 oz (240 mL) for dual A/C system
• Low-Side Service Port Location: Typically on the accumulator/dryer, near the firewall on the passenger side.
• High-Side Service Port Location: Usually on the larger A/C line, closer to the condenser, often near the passenger side headlight assembly.

Why R-1234yf Matters

For your 2019 Ford Transit, the refrigerant of choice is R-1234yf. This is a significant change from the R-134a used in older vehicles, primarily driven by environmental regulations. R-1234yf has a much lower Global Warming Potential (GWP) than R-134a, making it more eco-friendly. While this is great news for the environment, it does come with a few implications for vehicle owners and technicians.

Firstly, R-1234yf is considerably more expensive than R-134a. This means that a simple A/C recharge can be more costly. Secondly, due to its mild flammability, specialized equipment is required for its recovery and recharging. This means that not all shops are equipped to service R-1234yf systems, and it's crucial to find a facility with the proper EPA 609 certification and the correct R-1234yf specific recovery and recharge machine.

Recharge Procedure

Recharging your Ford Transit's A/C system isn't as simple as just adding a can of refrigerant until it feels cold. Proper A/C service requires precision. The most critical step is evacuating the system. This process uses a vacuum pump to remove all air and moisture, which can severely damage the A/C system components and reduce cooling performance. After evacuation, the system should be recharged with the exact amount of refrigerant specified, which for your 2019 Ford Transit is 22.9 oz (650 grams). This is almost always done by weight, not by monitoring pressure. While pressure gauges can give you a general idea, relying solely on them can lead to over or undercharging, both of which can lead to poor performance and potential compressor damage.

It's also crucial to ensure the correct type and amount of PAG oil is in the system. For a single A/C system, this is 6.0 oz (180 mL) of PAG 46 oil. For dual A/C systems, it increases to 8.1 oz (240 mL). Always use new, uncontaminated PAG oil of the correct viscosity.

Common A/C Problems for This Vehicle

While the Ford Transit is a robust vehicle, like any A/C system, it can experience common issues. Some potential problems you might encounter with your 2019 Ford Transit's A/C include:

• Compressor Failures: The A/C compressor is the heart of the system. Issues can arise from low refrigerant, improper lubrication, or internal mechanical failures. Signs include a noisy compressor, complete loss of cooling, or a clutch that won't engage.
• Condenser Issues: The condenser, usually located in front of the radiator, dissipates heat. It's susceptible to damage from road debris and can also develop leaks over time, leading to refrigerant loss.
• Evaporator Leaks: The evaporator, located inside the dashboard, is another common leak point. Due to its location, leaks here can be more challenging and costly to repair, sometimes requiring dashboard disassembly. A musty smell or visible water on the passenger floorboard can be symptoms.
• Blend Door Actuator Failures: While not strictly a refrigerant issue, a malfunctioning blend door actuator can prevent proper temperature control, leading to an A/C system that seems to blow air that's not as cold as it should be.

When to Call a Pro

Given the complexity of R-1234yf systems and the necessity of specialized equipment, A/C system repairs are best left to certified professionals. Attempting to service your A/C without the proper knowledge or tools can lead to further damage, costly repairs, and even personal injury. If you notice a reduction in cooling performance, strange noises from the A/C system, or a noticeable leak, it's time to consult an EPA 609 certified technician.

Safety Disclaimer: Working with automotive air conditioning systems can be dangerous. Refrigerants are under high pressure and can cause frostbite or other injuries if released improperly. It is illegal to release refrigerants into the atmosphere. Always wear appropriate personal protective equipment and consult a professional for A/C service. EPA 609 certification is required for anyone performing A/C service for compensation.
