2020 Nissan Titan Coolant Capacity & Type

The 2020 Nissan Titan with the 5.6L V8 engine holds approximately 12.3 quarts (11.6 liters) of coolant in its cooling system.

Quick Answer

• Total Cooling System Capacity: Approximately 12.3 quarts (11.6 liters)
• OEM Coolant Spec: Nissan Genuine Long Life Antifreeze/Coolant (Blue, Ethylene Glycol-based, extended-life, equivalent to Phosphated Hybrid Organic Acid Technology - P-HOAT).
• Mix Ratio: 50/50 Pre-mixed or concentrate to be mixed with distilled water.

Capacity by Engine Option

The 2020 Nissan Titan was offered with a single engine option, the 5.6L V8 (VK56VD).

Flush Interval

Nissan recommends a coolant flush and fill for the 2020 Titan every 105,000 miles or 84 months, whichever comes first, under normal driving conditions. For severe duty use (e.g., frequent towing, extreme temperatures, dusty conditions), it is advisable to shorten this interval to around 60,000 miles or 48 months to maintain optimal cooling system performance.

How to Refill & Bleed

Refilling and bleeding the cooling system on your 2020 Nissan Titan is crucial to prevent air pockets, which can lead to overheating. Here's a general procedure:

1. Drain the System: With the engine cool, place a drain pan under the radiator. Open the radiator drain cock (petcock) and remove the radiator cap to allow the system to drain completely. Some Titans may also have engine block drain plugs; consult your service manual for their location if you wish to drain the system more thoroughly.
2. Close Drain and Refill: Once drained, close the radiator drain cock. Begin refilling the radiator slowly with the specified Nissan Genuine Long Life Antifreeze/Coolant 50/50 mix. Fill until the coolant level reaches the filler neck.
3. Bleed Air: Install the radiator cap loosely. Start the engine and let it warm up with the heater set to maximum heat and fan speed low. This helps open the heater core valve and circulates coolant through the heater core. As the engine warms, the thermostat will open, and coolant will begin to circulate. Monitor the coolant level in the radiator and top it off as it drops.
4. Burp the System: Squeeze the upper and lower radiator hoses several times to help dislodge any trapped air. You may see bubbles rise in the radiator neck.
5. Check Reservoir: Once the engine reaches operating temperature and the cooling fan cycles on, turn the engine off. Allow it to cool completely. Check the coolant level in the radiator and the coolant reservoir. Top off if necessary. The reservoir should be filled to the "MAX" line when the engine is cold.
6. Final Check: After a few drive cycles, recheck the coolant level in both the radiator and the reservoir, topping off as needed. Be sure to properly dispose of old coolant.

Note for the 2020 Nissan Titan: No specific bleed screws are commonly found on the 5.6L V8 engine for this generation. The air bleeding process primarily relies on the method described above, allowing the engine to warm up and the thermostat to open to circulate coolant and self-purge air.

Common Cooling System Issues (2016-2024 Nissan Titan Generation)

While the 2020 Nissan Titan is generally reliable, some cooling system issues can arise in this generation:

• Water Pump Leaks: The water pump, like in many vehicles, can eventually develop leaks or fail. Keep an eye out for coolant puddles under the front of the vehicle or a noticeable drop in coolant level.
• Radiator Leaks: Radiators can develop leaks over time due to corrosion, stone chips, or manufacturing defects. Check for wet spots on the radiator fins or a sweet smell of coolant.
• Thermostat Issues: A faulty thermostat can lead to the engine running too hot (stuck closed) or too cold (stuck open). Symptoms include fluctuating temperature gauges or the engine taking a long time to warm up.
• Coolant Hose Leaks: Hoses can degrade over time, leading to cracks, bulges, or leaks at connection points. Periodically inspect hoses for any signs of wear.
• Coolant Reservoir Leaks: The plastic coolant reservoir can sometimes crack or develop leaks, leading to a loss of coolant.

Regular maintenance, including adhering to the recommended coolant flush intervals and inspecting components, can help prevent these issues.
