2025 Nissan Frontier Coolant Capacity & Type

The 2025 Nissan Frontier holds approximately 10.0 quarts (9.5 liters) of coolant in its cooling system.

Quick Answer

• Total Cooling System Capacity: 10.0 quarts (9.5 liters)
• OEM Coolant Spec: Nissan Genuine Long Life Antifreeze/Coolant (Blue, Phosphated Organic Acid Technology - POAT, Nissan L250 Super Long Life/Nissan L255NP)
• Mix Ratio: 50/50 Pre-mix or 50/50 Concentrate with distilled water

Capacity by Engine Option

The 2025 Nissan Frontier is expected to feature the 3.8L V6 engine across all trims, with a consistent coolant capacity.

Flush Interval

Nissan recommends specific coolant flush intervals to maintain optimal cooling system performance for your 2025 Frontier:

• Normal Duty: Replace initially at 105,000 miles or 84 months, then every 75,000 miles or 60 months thereafter.
• Severe Duty: If your vehicle is subjected to severe conditions (e.g., heavy towing, extreme temperatures, off-roading, frequent short trips), it's advisable to inspect your coolant more frequently and consider reducing the replacement interval. Typically, severe duty service might warrant replacement at 60,000 miles or 48 months.

Always consult your owner's manual for the most accurate and up-to-date maintenance schedule.

How to Refill & Bleed

Properly refilling and bleeding the cooling system in your 2025 Nissan Frontier is crucial to prevent air pockets, which can lead to overheating. Here's a general procedure:

1. Safety First: Ensure the engine is completely cool before attempting any work on the cooling system. Wear appropriate personal protective equipment (PPE) like gloves and eye protection.
2. Drain Coolant: If performing a flush, open the radiator drain cock (petcock) located at the bottom of the radiator and remove the radiator cap to allow the old coolant to drain completely. Some models may also have engine block drain plugs.
3. Flush System (Optional): If flushing, close the drain cock, refill with distilled water, run the engine with the heater on until it reaches operating temperature, then drain again. Repeat until the drained water is clear. Consider using a cooling system cleaner designed for your coolant type.
4. Refill: Close the radiator drain cock. Slowly add new Nissan Genuine Long Life Antifreeze/Coolant (Blue) to the radiator filler neck until it reaches the top. Fill the coolant reservoir to the "MAX" line.
5. Bleeding Air:
   • Start the engine with the radiator cap off (or loosely placed on top if splashing is an issue) and the heater set to full hot and fan on low. This helps open the heater core valve and circulate coolant through the entire system.
   • Allow the engine to idle and reach operating temperature. As the engine warms up, the thermostat will open, and coolant will begin to circulate. You may see the coolant level drop in the radiator as air escapes. Top it off as needed.
   • Gently squeeze the upper and lower radiator hoses several times to help dislodge trapped air bubbles.
   • Nissan Frontier models often benefit from utilizing specific bleed screws if present on the thermostat housing or other high points in the system. While the 2025 model
