2017 Ford Explorer A/C Refrigerant & Oil Capacity

Quick Answer

• Refrigerant Type: R-1234yf
• Full System Charge: 22 oz (624 grams)
• PAG Oil Type: PAG 46
• PAG Oil Amount: 6.76 fl oz (200 mL)
• Low-Side Service Port Location: On the accumulator/dryer, typically located near the firewall on the passenger side.
• High-Side Service Port Location: On the A/C line, usually found between the condenser and the firewall, closer to the passenger side.

Why R-1234yf Matters

The 2017 Ford Explorer uses R-1234yf refrigerant, a standard that became increasingly common in vehicles manufactured after 2014. This shift from the older R-134a refrigerant was driven by environmental concerns. R-1234yf has a significantly lower Global Warming Potential (GWP) compared to R-134a, making it more environmentally friendly.

However, this change comes with implications for both cost and servicing. R-1234yf is generally more expensive than R-134a. Furthermore, special equipment is required for its recovery and recharging. Standard R-134a recovery machines cannot be used with R-1234yf, as cross-contamination can damage both the vehicle's A/C system and the recovery equipment. Due to its mild flammability, R-1234yf also necessitates specific safety protocols and certified recovery machines designed to handle it safely during service.

Recharge Procedure

Recharging your 2017 Ford Explorer's A/C system is not as simple as just adding a can of refrigerant. It is crucial to emphasize that the system should be evacuated and recharged by weight, not pressure. Overcharging or undercharging, or simply topping off based on pressure readings, can lead to poor cooling performance, compressor damage, and other expensive repairs.

Here's a high-level overview of the proper procedure, which is best performed by a certified technician:

1. Recover Existing Refrigerant: Any remaining refrigerant in the system must be safely recovered using a dedicated R-1234yf recovery machine.
2. Evacuate the System: A vacuum pump is used to evacuate the system, removing air and moisture. This step is critical as moisture can mix with refrigerant to form corrosive acids, and air reduces cooling efficiency.
3. Leak Test: After evacuation, the system should hold a vacuum, indicating no significant leaks. If the vacuum doesn't hold, a leak detection process (e.g., using a nitrogen charge and leak detector, or UV dye) must be performed to identify and repair the leak.
4. Recharge by Weight: Based on the manufacturer's specifications (22 oz or 624 grams for your 2017 Ford Explorer), the precise amount of new R-1234yf refrigerant is charged into the system.
5. Add PAG Oil (if necessary): If components were replaced or a significant leak occurred, the appropriate amount of PAG 46 oil (6.76 fl oz or 200 mL for a full system) should be added. It's generally best to only add oil if a specific amount was lost, typically only with component replacement. Otherwise, technicians are careful not to overfill oil.

Common A/C Problems for This Vehicle

While the 2017 Ford Explorer is a generally robust vehicle, certain A/C issues can be common for this generation. These often include:

• Compressor Failures: The A/C compressor is the heart of the system. Issues can range from internal wear and tear to clutch problems (if applicable). Symptoms include no cold air, strange noises when the A/C is on, or a burning smell.
• Condenser Issues: The condenser, located at the front of the vehicle, dissipates heat. It's susceptible to damage from road debris, which can cause leaks. A clogged condenser (e.g., with bugs or dirt) can also hinder cooling efficiency.
• Evaporator Leaks: The evaporator, located inside the dashboard, cools the air entering the cabin. Leaks here are common due to corrosion or manufacturing defects and are often difficult and expensive to repair as they require significant dashboard disassembly.
• Blend Door Actuator Problems: While not a refrigerant issue, a faulty blend door actuator can prevent cold air from being directed to the cabin, leading to warm air from the vents even if the A/C system is otherwise functional.

When to Call a Pro

Many A/C system repairs require specialized tools, knowledge, and EPA 609 certification for handling refrigerants. If you're experiencing any of the following, it's best to consult a professional:

• Your A/C is blowing warm air.
• You hear unusual noises when the A/C is on.
• There's a visible leak or oily residue around A/C components.
• The A/C system cycles on and off rapidly.
• You suspect a refrigerant leak.

Safety Disclaimer: Working with automotive air conditioning systems and refrigerants can be dangerous. Refrigerants are under high pressure and can cause severe frostbite if they come into contact with skin or eyes. Inhaling large quantities can also displace oxygen and cause dizziness or suffocation. Always wear appropriate personal protective equipment, including safety glasses and gloves, and ensure adequate ventilation. Refrigerant recovery and handling should only be performed by individuals or shops certified by the EPA under Section 609 of the Clean Air Act.
