Nissan Armada 2025-2026 Owner's Manual: Basic information
The engine cooling system of the Nissan Armada is factory-filled with a precisely balanced mixture consisting of 50% Genuine NISSAN Long Life Antifreeze/Coolant (blue) and 50% water. This formulation ensures reliable year-round protection against freezing, overheating, and corrosion.
This advanced coolant used in the Nissan Armada includes corrosion inhibitors designed to protect internal engine components, making additional cooling system additives unnecessary under normal conditions.
Maintaining the correct coolant composition is essential for preserving engine efficiency, preventing overheating, and extending the service life of the Nissan Armada powertrain.
WARNING
- Never remove the radiator cap or coolant reservoir cap while the Nissan
Armada engine is hot. Allow sufficient time for the engine and cooling system
to cool down completely.
Opening the system under pressure may cause hot coolant to spray out, resulting in serious burns or injury.
- The radiator in the Nissan Armada uses a pressurized cap. Always use a genuine NISSAN radiator cap to ensure proper system operation and to prevent potential engine damage.
CAUTION
- Do not use cooling system additives such as sealants or stop-leak products
in the Nissan Armada.
These substances may clog passages within the cooling system and lead to serious damage to the engine, transmission, or radiator components.
- When topping up or replacing coolant in your Nissan Armada, use only
Genuine NISSAN Long Life Antifreeze/Coolant (blue) or a fully compatible equivalent.
This coolant is pre-diluted to provide freeze protection down to −34°F (−37°C). If operating in extremely cold climates, additional concentrate may be added according to manufacturer instructions.
If using an alternative coolant, carefully follow the product guidelines to ensure equivalent protection. Using incorrect coolant types may compromise the Nissan Armada cooling system and lead to costly repairs.
- The factory-filled coolant in the Nissan Armada is designed to last up
to 105,000 miles (168,000 km) or approximately 7 years under normal driving
conditions.
Mixing different coolant types, including green antifreeze or non-distilled water, may significantly reduce its lifespan and effectiveness.
Refer to the maintenance schedule for detailed service intervals and always maintain the correct coolant quality for optimal Nissan Armada performance.
Regular inspection of coolant levels and components in the Nissan Armada engine bay helps ensure reliable operation and prevents overheating issues, especially during demanding driving conditions.
Checking engine coolant level
For optimal performance and reliability of your Nissan Armada, always check the
engine coolant level when the engine is completely cold.
Inspect the coolant level in the reservoir tank. If th ...
