2019 Ford F-150: A/C Refrigerant & Oil Specifications

Quick answer: 2019 F-150 A/C specs

• Refrigerant type: R-1234yf
• System charge amount: 34.0 oz (964 g)
• PAG oil type: PAG 46
• Oil capacity: 4.5 oz (133 mL)
• Low-side port location: Near the firewall, on the passenger side of the engine bay
• High-side port location: In front of the radiator, near the hood latch

Why R-1234yf matters

Starting in 2014, Ford began transitioning its vehicle fleet from R-134a to the more environmentally friendly R-1234yf refrigerant. By 2019, all F-150s were factory-filled with R-1234yf. This new refrigerant has a much lower global warming potential (GWP) than its predecessor, but it comes with some important differences for the service and repair process.

First, R-1234yf is significantly more expensive than R-134a. Second, it requires specialized equipment for recovery and recharging, as it is mildly flammable. Finally, it is crucial to use only R-1234yf in a system designed for it; cross-contamination can damage A/C components and lead to poor performance.

Recharge procedure

A proper A/C recharge is not just about topping off the system. To ensure optimal performance and longevity, the system should be evacuated for at least 30 minutes to remove any moisture and air before recharging with the precise weight of refrigerant specified by the manufacturer. Recharging by pressure can lead to an undercharged or overcharged system, which can cause damage to the compressor and other components.

Common A/C problems for this vehicle

While the 2019 F-150 has a generally reliable A/C system, some common issues have been reported. These include:

• Compressor failures: The A/C compressor is the heart of the system, and failures can be costly. Symptoms include a lack of cold air, strange noises from the engine bay, or a visible leak from the compressor body.
• Condenser issues: The condenser, located in front of the radiator, is susceptible to damage from road debris. A leak in the condenser will cause a loss of refrigerant and a gradual decline in A/C performance.
• Evaporator leaks: The evaporator is located inside the dashboard and is responsible for cooling the air that enters the cabin. A leak in the evaporator can be difficult to diagnose and may require the removal of the entire dashboard for replacement.

When to call a pro

While some DIYers may be tempted to tackle A/C repairs themselves, the specialized equipment and training required for working with R-1234yf make it a job best left to the professionals. Additionally, the EPA requires that anyone servicing a motor vehicle A/C system be certified under Section 609 of the Clean Air Act.
