2015 Ford Explorer A/C Refrigerant and Oil Specifications

Quick Answer: 2015 Explorer A/C Specs

• Refrigerant Type: R-134a
• Refrigerant Charge: 36 oz (1020g)
• PAG Oil Type: PAG 46 (Motorcraft YN-12-D)
• Total PAG Oil Capacity: 6.0 oz (177 mL)
• Low-Side Port Location: Near the passenger-side firewall, behind the shock tower.
• High-Side Port Location: In front of the radiator support, near the hood latch.

Why R-1234yf Matters (But Not for Your 2015 Explorer)

While the automotive industry began a government-mandated transition to the more environmentally friendly R-1234yf refrigerant around 2014, the 2015 Ford Explorer still uses the older R-134a refrigerant. This is good news for the DIYer, as R-134a is significantly less expensive and more readily available.

However, it's crucial not to mix these two refrigerants. R-1234yf systems operate at different pressures and require specific, more expensive service equipment. Using the wrong refrigerant or oil can lead to poor performance and catastrophic system damage. All A/C work, regardless of refrigerant type, requires specialized equipment like a recovery/recharge machine, and technicians must be certified by the EPA.

A/C Recharge Procedure Essentials

Topping off an A/C system with a can from the auto parts store is not a proper repair. A/C is a closed system; if it's low on refrigerant, it has a leak. Simply adding more refrigerant without fixing the leak is a temporary fix at best and harmful to the environment. Gauges that read pressure are not a reliable way to charge a system.

The correct procedure involves:

1. Recovery: Using an EPA-approved machine to safely recover all existing refrigerant from the system.
2. Evacuation: Pulling the system into a deep vacuum for at least 30-45 minutes. This removes all air and moisture, which can turn into corrosive acids when mixed with refrigerant and oil.
3. Charging: Recharging the system with the precise weight of refrigerant specified by the manufacturer (36 oz for the 2015 Explorer). This is the only way to ensure proper performance and system longevity.

Common A/C Problems: 2011-2019 Ford Explorer

• Compressor Failure: The A/C compressor clutch is a frequent point of failure. You might hear noises when the A/C is engaged or notice that the compressor isn't cycling on at all. Sometimes, the entire compressor may need to be replaced.
• Condenser Leaks: Located at the very front of the vehicle, the condenser is susceptible to damage from road debris. Leaks here are common and can often be identified by oily residue and dirt collecting on the fins.
• Evaporator Core Leaks: This is a more labor-intensive repair, as the evaporator is located deep inside the dashboard. A musty smell from the vents or fogging on the inside of the windshield when the A/C is running can sometimes indicate an evaporator leak. A technician can use a refrigerant "sniffer" or inject UV dye to confirm the leak's location.

When to Call a Professional

Anytime your A/C system requires more than a basic cabin air filter change, it's time to call in a professional. Legally, anyone servicing a mobile A/C system must be EPA Section 609 certified and use a recovery/recharge machine. This equipment is expensive and not feasible for most DIY mechanics.

An experienced technician can accurately diagnose the root cause of your A/C problem, whether it's an electrical issue, a failed component, or a hard-to-find leak. They have the tools and expertise to perform a lasting repair safely and legally.

Disclaimer: Handling refrigerants requires EPA Section 609 certification. Always wear safety glasses and gloves. Improper service can cause injury and damage to your vehicle.
