Quick answer
- Refrigerant type: R-1234yf
- Full system charge: 19.4 oz (550g)
- PAG oil type: PAG 46
- PAG oil amount: 4.1 oz (120mL)
- Low-side service port location: Near the passenger-side firewall
- High-side service port location: Near the radiator support
Why R-1234yf matters
The 2025 Nissan Altima uses R-1234yf refrigerant, which has a lower global warming potential than the R-134a used in older vehicles. This change was mandated by the EPA starting in 2014. While better for the environment, R-1234yf is more expensive and requires special equipment for service. You cannot use R-134a in a system designed for R-1234yf.
Recharge procedure
A proper A/C recharge is not a simple top-off. The correct procedure involves:
- Evacuation: The system must be fully evacuated of all refrigerant using a recovery machine.
- Vacuum: A deep vacuum is then drawn on the system to remove any moisture.
- Charging: The exact amount of refrigerant is added by weight, not pressure. Overcharging or undercharging can damage the system.
Common A/C problems for this vehicle
While the 2025 Altima is a new model, common A/C problems in this platform include:
- Compressor failures: The A/C compressor is a common failure point. Symptoms include a lack of cold air, strange noises, or a seized compressor clutch.
- Condenser issues: The condenser, located in front of the radiator, is susceptible to damage from road debris. A damaged condenser can leak refrigerant.
- Evaporator leaks: The evaporator, located inside the dashboard, can develop leaks. This is a difficult and expensive repair.
When to call a pro
Due to the specialized equipment and training required to work with R-1234yf, it is recommended that you have your A/C system serviced by a professional. EPA 609 certification is required to legally purchase and handle refrigerants.
