2017 Nissan Titan: A/C Refrigerant & Oil Specifications

Quick Answer

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

Why R-1234yf Matters

Starting in 2014, manufacturers began transitioning from R-134a to the more environmentally friendly R-1234yf. The 2017 Nissan Titan uses R-1234yf, which has a much lower global warming potential (GWP) than its predecessor. However, this change comes with a few considerations for the vehicle owner. R-1234yf is more expensive than R-134a, and it requires a dedicated recovery machine. This means that not all shops are equipped to handle R-1234yf systems. It is also important to note that R-1234yf is mildly flammable, so it requires special handling procedures.

Recharge Procedure

A/C system recharging is not as simple as just adding more refrigerant. To ensure proper cooling and system longevity, the system must be evacuated of all refrigerant, moisture, and air before being recharged to the manufacturer's specifications. This process should be done by weight, not by pressure. Overcharging or undercharging the system can lead to poor performance and damage to the compressor.

Common A/C Problems for this Vehicle

While the 2017 Nissan Titan has a generally reliable A/C system, there are a few common issues that owners may encounter:

• Compressor Failures: The A/C compressor is the heart of the system, and it is also the most common point of failure. Compressor failures can be caused by a variety of factors, including low refrigerant levels, contamination, and old age.
• Condenser Issues: The condenser is located in front of the radiator, and it is responsible for dissipating heat from the refrigerant. Because of its location, the condenser is susceptible to damage from road debris. A damaged condenser can lead to a loss of refrigerant and poor cooling performance.
• Evaporator Leaks: The evaporator is located inside the dashboard, and it is responsible for cooling the air that blows into the cabin. Evaporator leaks are less common than other A/C problems, but they can be difficult and expensive to repair.

When to Call a Pro

While some basic A/C maintenance tasks can be performed by the do-it-yourselfer, most A/C repairs should be left to a professional. A/C systems are complex, and they require special tools and knowledge to service properly. If you are experiencing any of the following problems, it is time to call a certified A/C technician:

• The A/C is not blowing cold.
• The A/C is making strange noises.
• There is a leak in the A/C system.
