The Nissan Maxima’s air conditioning system uses a refrigerant, not an engine coolant, and the exact type depends on the model year. In short: older Maxima models typically use R-134a, while newer models use R-1234yf. Confirm with the under-hood label or the owner's manual before refilling.
Refrigerant types used by the Maxima
Automakers shifted refrigerants over time in response to environmental rules. The Maxima follows those changes, so the required refrigerant depends on when the car was built and where it was sold.
By model year and market
Below is a general guide. Always check the refrigerant label on the vehicle and the owner's manual, since there can be regional variations.
- Pre-2017 Maxima models: typically R-134a refrigerant. This was the standard for many vehicles before the shift to lower-GWP refrigerants.
- 2017 and newer Maxima models (especially in North America and many markets): commonly use R-1234yf refrigerant. This is the newer, lower-GWP refrigerant used across many modern vehicles.
- Regional variations: some markets or special editions may differ; always verify with the under-hood service label and the owner's manual.
In addition to the refrigerant, the system uses lubricant compatible with the refrigerant: PAG oil for R-134a systems and POE oil for R-1234yf systems. Never mix lubricants or refrigerants, and follow the service procedure for proper recovery and recharge.
Concluding: The exact refrigerant for your Nissan Maxima depends on the year and market. Check the label on the service port and the owner's manual to confirm before servicing the A/C system. If in doubt, consult a qualified automotive HVAC technician.
Summary
Answer: The Nissan Maxima takes R-134a refrigerant in older models and R-1234yf in newer ones. Verify with the vehicle’s label to avoid mistakes, and use the correct lubricant and proper recovery/recharge procedures.
What kind of refrigerant does a Nissan Maxima take?
Essential Nissan Maxima Refrigerants
Certified A/C Pro R-134a PAG 46 Refrigerant Oil with ICE 32. This product contains approximately 8 fluid ounces of PAG refrigerant oil with ICE32.
What coolant does Nissan Maxima use?
Pentosin – Pentofrost A3 HOAT Phosphated Asian 50/50 Prediluted Antifreeze / Coolant – 1 Gallon (Part No. 8115207) Pentofrost A3 is a phosphated organic acid technology (phosphated OAT); which is categorized as HOAT (hybrid organic acid technology) in the US market.
Does it matter what AC coolant you use?
R-410a has replaced R-22 as the standard in most new AC systems. It cools efficiently and is more environmentally friendly. It does still use harsh chemicals, but the overall impact is far less. However, if you want to replace the coolant in an older system, R-410a might not be the best option.
Does my car use R-134a or R-1234yf?
Cars built mid-1990s to roughly 2014–2017 almost always use R134a. Most 2017–present vehicles, especially Euro, hybrid and EV models, use R-1234yf. Some EVs use specialised refrigerant blends depending on the cooling system. Your car has a sticker under the bonnet that confirms its exact gas type.
