2016 Ford Explorer: A/C Refrigerant and Oil Specifications

Quick answer

• Refrigerant Type: R-1234yf
• Full System Charge: 34.5 oz (978g)
• PAG Oil Type: PAG 46
• PAG Oil Amount: 6.8 oz (200mL)
• Low-Side Service Port Location: Near the firewall, on the passenger side of the engine bay.
• High-Side Service Port Location: In front of the radiator, on the driver's side.

Why R-1234yf matters

The 2016 Ford Explorer uses R-1234yf refrigerant, which has a lower global warming potential than the older R-134a. This makes it more environmentally friendly, but it also comes with some important considerations for service and repair.

• Cost: R-1234yf is significantly more expensive than R-134a, which can increase the cost of A/C repairs.
• EPA Regulations: Due to its environmental benefits, the EPA has mandated the use of R-1234yf in all new vehicles. This means that older refrigerants cannot be used in your 2016 Explorer.
• Recovery Machine Requirements: Servicing a vehicle with R-1234yf requires a specific recovery machine that is designed for this type of refrigerant. This is because R-1234yf is mildly flammable, and the recovery machine must be able to handle it safely.

Recharge procedure

A proper A/C recharge is not just about adding refrigerant. It's a precise process that requires specialized equipment and knowledge. Here's a high-level overview of the steps involved:

1. Evacuation: The first step is to evacuate the A/C system to remove all of the old refrigerant, oil, and any moisture that may be present. This is done using a recovery machine, which creates a vacuum in the system.
2. Vacuum Hold: Once the system is evacuated, it should be held under a vacuum for at least 30 minutes to ensure that there are no leaks.
3. Charge by Weight: The A/C system must be charged with the precise amount of refrigerant specified by the manufacturer. This is done by weight, not by pressure. Overcharging or undercharging the system can cause damage to the A/C components.
4. Add PAG Oil: The correct type and amount of PAG oil must be added to the system. PAG oil lubricates the A/C compressor and other components.

Common A/C problems for this vehicle

While the 2016 Ford Explorer is a reliable vehicle, it is not without its share of A/C problems. Here are some of the most common issues that we see:

• Compressor Failures: The A/C compressor is the heart of the system, and it is a common failure point on the 2016 Explorer. Symptoms of a failing compressor include a lack of cold air, strange noises coming from the engine bay, and a visible leak from the compressor itself.
• Condenser Issues: The condenser is located in front of the radiator, and it is responsible for cooling the refrigerant. It is susceptible to damage from road debris, which can cause leaks and a loss of cooling.
• Evaporator Leaks: The evaporator is located inside the dashboard, and it is responsible for cooling the air that blows into the cabin. Evaporator leaks are difficult to diagnose and repair, and they often require the removal of the entire dashboard.

When to call a pro

While some basic A/C maintenance can be done at home, it is always best to leave the more complex repairs to a professional. If you are experiencing any of the following, it is time to call a certified A/C technician:

• Your A/C is not blowing cold air.
• You hear strange noises coming from the engine bay.
• You see a visible leak from the A/C system.
• You suspect that your A/C system has a leak.

Disclaimer: It is illegal to handle refrigerants without an EPA 609 certification. Attempting to service your own A/C system without the proper training and equipment can be dangerous and harmful to the environment.
