2019 Ford Ranger A/C Refrigerant & Oil Capacity

Quick Answer

• Refrigerant Type: R-1234yf
• Full System Charge: 17.6 oz (500 grams)
• PAG Oil Type: PAG 46
• PAG Oil Amount: 4.7 fl oz (140 mL)
• Low-Side Service Port Location: On the accumulator/drier, near the firewall on the passenger side.
• High-Side Service Port Location: On the A/C line, typically near the condenser on the passenger side, closer to the front of the vehicle.

Why R-1234yf Matters

The 2019 Ford Ranger utilizes R-1234yf refrigerant, a significant change from the R-134a commonly used in vehicles prior to the mid-2010s. This transition was driven by environmental concerns, as R-1234yf has a much lower Global Warming Potential (GWP) than R-134a. While better for the planet, this newer refrigerant comes with a few considerations:

• Cost: R-1234yf is generally more expensive than R-134a, which can impact the cost of A/C repairs or recharges.
• EPA Regulations: Due to its environmental impact, the handling and disposal of R-1234yf are subject to strict EPA regulations. Only certified technicians are legally allowed to purchase and work with this refrigerant.
• Specialized Equipment: Servicing an R-1234yf system requires specialized recovery and recharging equipment. These machines are designed to prevent cross-contamination with R-134a and ensure accurate charging by weight.

Recharge Procedure

Recharging your 2019 Ford Ranger's A/C system is not as simple as adding a can of refrigerant. Proper procedure is crucial for system longevity and effective cooling:

1. Evacuation: The system must first be evacuated using a vacuum pump to remove any air and moisture. Moisture in the A/C system can lead to component corrosion and system failure.
2. Leak Test: After evacuation, the system should hold a vacuum for a specified period to confirm there are no leaks. If a leak is present, it must be repaired before adding refrigerant.
3. Proper Charge by Weight: The most critical step is charging the system with the precise amount of R-1233yf by weight, not by pressure. Overcharging or undercharging can lead to poor cooling, increased compressor wear, and potential damage to the system. The exact charge for your 2019 Ford Ranger is 17.6 oz (500 grams).
4. PAG Oil Addition: If components were replaced or the system was opened, the appropriate amount of PAG 46 oil (4.7 fl oz or 140 mL) must be added. Refer to an OEM service manual for proper oil measurement and distribution in the system after component replacement.

Safety Disclaimer: Working with automotive A/C systems and refrigerants can be dangerous. Refrigerants can cause frostbite, and system pressures are high. It is strongly recommended that A/C service and repair be performed by an EPA 609 certified technician using appropriate safety equipment and specialized tools.

Common A/C Problems for the 2019 Ford Ranger

While the 2019 Ford Ranger is a relatively new vehicle, some common A/C issues can arise:

• Refrigerant Leaks: Leaks can occur at various points, including O-rings, hoses, fittings, the compressor, condenser, or evaporator. Due to the high cost of R-1234yf, even small leaks can be costly to address.
• Condenser Issues: The condenser is located at the front of the vehicle and is vulnerable to damage from road debris. A damaged condenser can leak refrigerant or restrict airflow, impacting cooling performance.
• Blower Motor Problems: While not directly related to the refrigerant circuit, a failing blower motor or resistor can prevent air from circulating through the cabin, leading to perceived A/C issues.
• Electrical Problems: Issues with A/C related sensors, relays, or wiring can prevent the system from engaging or functioning correctly.

When to Call a Pro

If you're experiencing any of the following symptoms with your 2019 Ford Ranger's A/C, it's best to consult a certified professional:

• No cold air, or air that's not as cold as it used to be.
• Unusual noises coming from the engine bay when the A/C is on.
• Visible leaks of fluid (often appearing oily) under the vehicle.
• A burning smell when the A/C is running.
• The A/C only works intermittently.

Given the complexities of R-1234yf systems and the need for specialized equipment, attempting a DIY repair beyond basic visual inspection is not recommended. A professional can accurately diagnose the issue, safely recover and recharge the refrigerant, and ensure your system operates efficiently.
