2017 Nissan Titan: Coolant Capacity & Type

The 2017 Nissan Titan has a total cooling system capacity of approximately 15.6 quarts (14.8 liters) for models equipped with the 5.6L V8 gasoline engine.

Quick Answer

• Total Capacity: 15.6 quarts / 14.8 Liters (5.6L V8)
• OEM Coolant: Nissan Blue Long Life Antifreeze/Coolant (P/N 999MP-L25500P)
• Coolant Type: Blue, Phosphated HOAT (Hybrid Organic Acid Technology)
• Mix Ratio: 50/50 with distilled water (pre-mixed is recommended)

Capacity by Engine Option

The second-generation Nissan Titan (2016-present) primarily features one gasoline engine, simplifying coolant specifications.

Note: These values represent the total system capacity, including the engine, radiator, and heater core. A simple drain-and-fill will typically replace 60-70% of this amount.

Flush Interval

Following the factory-recommended service interval is crucial for protecting your Titan's engine from corrosion and overheating.

• Initial Flush: The first coolant flush is recommended at 105,000 miles or 7 years, whichever comes first.
• Subsequent Flushes: After the initial service, change the coolant every 75,000 miles or 5 years.
• Severe Duty: If you frequently tow heavy loads, operate in extreme temperatures, or drive in dusty conditions, consider shortening the interval to 60,000 miles to be safe.

How to Refill & Bleed

Properly refilling and bleeding the cooling system is critical to prevent air pockets, which can cause overheating and damage to your engine.

1. Mix Coolant: If using concentrate, mix it 50/50 with distilled water in a clean bucket. Do not use tap water, as its mineral content can cause scaling and corrosion.
2. Refill Slowly: With the engine off and cool, slowly pour the coolant into the coolant reservoir (not directly into the radiator). Fill it to the "MAX" line.
3. Bleeding the System: Unlike many vehicles, the 2017 Titan does not have a traditional radiator cap or easily accessible bleed screws. The system is designed to be self-bleeding, but air can still get trapped.
   • After filling, leave the reservoir cap off.
   • Start the engine and let it idle. Turn the heater on to the highest temperature and the fan to a low setting. This circulates coolant through the heater core.
   • As the engine warms up, the thermostat will open, and you should see the coolant level in the reservoir drop. Continue to add coolant to keep the level between the "MIN" and "MAX" lines.
   • Pro Tip: Gently squeezing the upper radiator hose can help push trapped air bubbles toward the reservoir.
   • A "spill-free" funnel kit, which attaches directly to the reservoir opening, is highly recommended to make this process cleaner and more effective.
4. Final Check: Once the engine reaches operating temperature and no more air bubbles are seen, top off the reservoir to the "MAX" line and replace the cap. Check the coolant level again after the vehicle has cooled down completely.

Common Cooling System Issues

The 2017+ Nissan Titan has a generally reliable cooling system, but some issues can arise, often related to components shared across the Nissan lineup:

• Coolant Leaks: The most common sources of leaks include the radiator (especially where the plastic end tanks meet the aluminum core), water pump gaskets, and heater hoses that connect to the firewall.
• Thermostat Failure: A thermostat stuck open can lead to the engine never reaching full operating temperature and poor heater performance. A thermostat stuck closed will cause rapid overheating.
• Radiator Blockage: External blockage from debris (bugs, leaves) can reduce airflow and cooling efficiency. Internal blockage from using incorrect coolant or neglecting service intervals can also occur, though it is less common with modern long-life coolants.
