2022 Nissan Titan A/C Refrigerant and Oil Specifications

Quick Answer: 2022 Titan A/C Specs

• Refrigerant Type: R-1234yf
• Refrigerant Charge: 26.5 oz (750g)
• PAG Oil Type: PAG 46
• PAG Oil Capacity (Full System): 4.1 oz (120 mL)
• Low-Side Port Location: Near the firewall, on the passenger side of the engine bay.
• High-Side Port Location: In front of the radiator, on the driver's side.

Why R-1234yf Matters

Starting around 2014, automakers began transitioning from R-134a to the more environmentally friendly R-1234yf refrigerant. Your 2022 Titan uses R-1234yf, which has a much lower Global Warming Potential (GWP). While this is great for the atmosphere, it comes with a few trade-offs for the vehicle owner:

• Cost: R-1234yf is significantly more expensive than R-134a.
• Specialized Equipment: Servicing R-1234yf systems requires dedicated, spark-proof recovery and charging machines. This is not a DIY-friendly task.
• Mild Flammability: R-1234yf is classified as mildly flammable, which is another reason specialized equipment and training are required.

Recharge Procedure

It is no longer best practice to "top off" an A/C system. The correct procedure involves a full evacuation and recharge by weight.

1. Recover: A certified technician will use an R-1234yf-specific machine to recover any remaining refrigerant from the system.
2. Evacuate: The system is placed under a deep vacuum for at least 30-45 minutes to boil off any moisture.
3. Charge: The exact weight of refrigerant (26.5 oz / 750g for a 2022 Titan) is added back into the system.

A note on oil: If the system was flushed or a component (like the compressor or condenser) was replaced, the technician will add the specified amount of PAG 46 oil.

Common A/C Problems for this Nissan Titan Generation

While the second-generation Titan is generally reliable, some common A/C issues to watch for include:

• Condenser Damage: The condenser sits in front of the radiator and is susceptible to damage from road debris. A leak in the condenser is a common reason for the A/C to stop blowing cold.
• Compressor Failure: The A/C compressor is the heart of the system. Over time, internal seals can wear out, or the clutch can fail.
• Evaporator Leaks: Though less common, a leak can develop in the evaporator core, which is located inside the dashboard. This is a labor-intensive repair.

When to Call a Pro

Due to the cost of R-1234yf and the specialized equipment required, any A/C service on a 2022 Titan should be performed by a qualified shop. If you notice your A/C isn't as cold as it used to be, it's time to have it professionally inspected.

Disclaimer: The EPA requires anyone servicing motor vehicle air conditioning systems to be Section 609 certified.
