Ford Explorer Refrigerant Type by Generation
The refrigerant used in the Ford Explorer has changed over the years. Identifying the correct type is essential before performing AC maintenance or repairs.
First Generation (1991–1994)
The first-generation Ford Explorer used R-12 refrigerant in 1991, 1992, and 1993. These models have a reference capacity of approximately 32 ounces.
In 1994, Ford switched to R-134a refrigerant, with a listed capacity of approximately 36 ounces.
R-12 is an older refrigerant that is no longer commonly available. Converting an older Explorer from R-12 to R-134a requires compatible components and the correct conversion procedure.
Second Generation (1995–2001)
The second-generation Ford Explorer uses R-134a refrigerant.
The reference capacities vary by model year:
- 1995–1996: 26 ounces.
- 1997: 22 ounces.
- 1998–2001: 30 ounces.
These models generally use PAG refrigerant oil. However, the correct oil specification and quantity should be confirmed before servicing.

Third Generation (2002–2005)
The 2002–2005 Ford Explorer uses R-134a refrigerant.
One important consideration is whether the vehicle has rear auxiliary air conditioning.
Models without rear AC have a reference refrigerant capacity of approximately 34 ounces, while models equipped with rear AC require approximately 56 ounces.
The additional refrigerant is necessary because rear AC systems have extra refrigerant lines and cooling components.
Fourth Generation (2006–2010)
The fourth-generation Ford Explorer also uses R-134a refrigerant.
The capacity depends on the model year and AC configuration:
- 2006–2008 without rear AC: 31 ounces.
- 2006–2008 with rear AC: 47 ounces.
- 2009–2010 without rear AC: 27 ounces.
- 2009–2010 with rear AC: 44 ounces.
Always check whether your Explorer has a rear evaporator before determining the correct refrigerant quantity.

Fifth Generation (2011–2019)
The fifth-generation Ford Explorer uses R-134a refrigerant.
However, refrigerant capacity varies depending on the engine and vehicle configuration.
For example, 2013 and 2015 Explorer models equipped with the 2.0L and 3.5L EcoBoost engines have a reference capacity of approximately 47 ounces. Models with the naturally aspirated 3.5L Ti-VCT engine have a reference capacity of approximately 41 ounces.
The 2019 Explorer also has different capacities depending on engine and drivetrain configuration.
Sixth Generation (2020–2025)
The sixth-generation Ford Explorer introduced R-1234yf refrigerant in place of the older R-134a.
The 2020 Explorer has a listed AC refrigerant capacity of 35 ounces (0.99 kg).
Later models have different specifications depending on the vehicle configuration. For example, the 2024 Explorer has a listed capacity of 16.2 ounces (0.46 kg) for the specified AC system.
Do not assume every sixth-generation Explorer uses the same refrigerant charge. Check the underhood AC label for the correct specification.

Ford Explorer AC Compressor Oil Capacity
Besides refrigerant, the air conditioning system requires compressor oil to lubricate moving components and reduce friction.
Most older Ford Explorer models use PAG oil, although the required quantity varies by generation and AC configuration.
The following table provides general reference values.
| Model Year | Compressor Oil Type | Reference Oil Capacity |
|---|---|---|
| 1991–1993 | Mineral oil | 7 oz |
| 1994–1996 | PAG-46 | 7 oz |
| 1997–2001 | PAG-46 | 9 oz |
| 2002–2005 without rear AC | PAG-46 | 9 oz |
| 2002–2005 with rear AC | PAG-46 | 13 oz |
| 2006–2008 without rear AC | PAG-46 | 9 oz |
| 2006–2008 with rear AC | PAG-46 | 16 oz |
| 2009–2010 | PAG-46 | Varies |
| 2011–2018 | PAG-46 | Varies |
| 2019 | PAG-46 | Varies by configuration |
| 2020 | Specified R-1234yf-compatible oil | Verify service specification |
These are reference values, not instructions to add the full quantity during every recharge. The correct oil amount depends on the vehicle and whether components such as the compressor, condenser, evaporator, or accumulator have been replaced.
Never mix different refrigerant oils without confirming compatibility.

Signs Your Ford Explorer Needs AC Refrigerant
An Explorer with insufficient refrigerant may struggle to maintain comfortable cabin temperatures, especially during hot weather.
Here are some common symptoms to watch for.
1. Warm Air From AC Vents
One of the most common signs of low refrigerant is warm air coming from the dashboard vents. When refrigerant levels are too low, the system may not transfer heat effectively.
However, warm air can also result from a faulty compressor, blocked condenser, electrical problem, or malfunctioning blend door.
2. Weak Cooling Performance
Your Explorer’s AC may initially produce cool air but gradually become less effective. This can indicate low refrigerant, a refrigerant leak, or another AC system problem.
3. AC Compressor Cycling Frequently
The compressor may switch on and off more frequently than normal when refrigerant pressure is outside the required operating range.
Low refrigerant can cause this behavior, but electrical and pressure-control problems can produce similar symptoms.
4. Unusual AC System Noises
Unusual noises when operating the AC may indicate compressor problems or insufficient lubrication. However, noise alone does not confirm low refrigerant.
5. Refrigerant Leaks
Oil residue around AC connections, hoses, or compressor fittings may indicate a refrigerant leak. A professional inspection can help identify the source.
How to Recharge Ford Explorer AC Refrigerant
Recharging the AC system requires the correct refrigerant, equipment, and charging procedure.
The basic process involves:
- Identify the refrigerant type using the underhood AC label.
- Inspect the AC system for leaks and damaged components.
- Recover any remaining refrigerant using approved recovery equipment.
- Repair leaks before recharging.
- Evacuate the system using a vacuum pump.
- Recharge the system using the exact specified refrigerant weight.
- Check AC pressures and cooling performance.
Avoid charging the system based only on pressure readings. The correct refrigerant quantity should be measured by weight.
Never mix R-134a and R-1234yf. They are different refrigerants and require compatible, dedicated servicing equipment.
