2022 Nissan Titan Coolant Capacity & Type

The 2022 Nissan Titan holds approximately 14.3 to 15.1 quarts (13.5 to 14.3 liters) of coolant, depending on the specific towing package and cab configuration. As an ASE-certified master technician, I regularly service the VK56VD 5.6-liter V8 engine found in these trucks, and ensuring the correct coolant capacity and chemistry is critical for the longevity of your cooling system. Below is everything you need to know about keeping your Titan’s engine running at the perfect operating temperature.

Quick answer

• Total cooling system capacity: 14.3 – 15.1 quarts (13.5 – 14.3 liters).
• OEM coolant spec: Genuine Nissan Blue Long Life Antifreeze/Coolant. This is a Phosphated Organic Acid Technology (P-OAT) formula specifically designed for Asian vehicles.
• Mix ratio: 50/50 pre-mixed (distilled water and antifreeze). Do not add plain tap water, as the minerals will degrade the P-OAT chemistry and cause scaling.

Capacity by engine option

For the 2022 model year, Nissan streamlined the Titan lineup, removing the previous diesel option. All 2022 Nissan Titans come equipped with the 5.6L Endurance V8. Capacities can vary slightly based on heavy-duty cooling packages equipped on the XD or Max Tow models.

Note: Total capacity includes the heater core and the coolant recovery reservoir. When doing a standard drain and fill, you will likely only need about 2 to 2.5 gallons of pre-mixed coolant, as some old fluid remains in the engine block.

Flush interval

Nissan’s Blue Long Life coolant is incredibly durable, but it isn't a "lifetime" fluid.

• Normal Duty: Nissan recommends the first factory coolant replacement at 105,000 miles or 7 years (whichever comes first). Subsequent replacements should be performed every 75,000 miles or 5 years.
• Severe Duty: If you frequently use your Titan for heavy towing, off-roading, or extensive idling, I strongly recommend a flush interval of 60,000 miles or 4 years. High-load driving breaks down the coolant's corrosion inhibitors much faster.

How to refill & bleed

The 5.6L V8 can be stubborn when it comes to air pockets. While a vacuum-fill tool is the best professional method, you can perform a manual bleed at home:

1. Drain the system: Wait until the engine is completely cold. Open the radiator petcock (bottom corner) and drain the old fluid into a catch pan.
2. Fill slowly: Attach a spill-free funnel to the radiator neck. Slowly pour in the 50/50 Nissan Blue coolant to prevent trapping large air bubbles. Fill the reservoir to the "MAX" line.
3. Burp the system: Start the engine with the funnel still attached and filled a third of the way. Turn the climate control heater to the maximum temperature and the blower fan to low. This opens the heater control valve.
4. Idle and observe: Let the truck idle until it reaches operating temperature and the thermostat opens (you'll feel the upper radiator hose get hot). Squeeze the upper hose carefully to help push out trapped air.
5. Final top-off: Once the cooling fans cycle on and off and bubbles stop appearing in the funnel, turn off the engine. Let it cool, remove the funnel, install the radiator cap, and double-check the reservoir level.

Common cooling system issues

For this generation of the Nissan Titan (2017+), the cooling system is generally robust, but there are a few things to watch out for as the miles pack on:

• Radiator End Tanks: Like most modern vehicles, the Titan uses plastic radiator end tanks crimped to an aluminum core. Over time, thermal cycling can cause hairline cracks in the plastic, leading to slow leaks.
• Water Pump Weep Hole: The mechanical water pump on the 5.6L V8 can begin to fail around the 80,000 to 100,000-mile mark. Keep an eye out for a crusty blue residue around the water pump weep hole—a telltale sign the internal seal is failing.
• Heater Hose Connectors: The plastic T-fittings and quick-connects routing coolant to the heater core become brittle with age and heat. Be gentle around them when doing under-hood maintenance.

Keeping your coolant fresh and filled to the correct level is the best way to protect your engine. If you aren't comfortable tackling a coolant flush yourself or suspect a leak, leave it to the pros. Find a trusted shop on Repairius.
