Parts for your 2014 Nissan Navara-Coolant

2014 Nissan Navara Coolant — What it is, why it matters, and how to look after it

Coolant is absolutely used on the 2014 Nissan Navara. Nissan’s own technical literature — including the Navara D40 Series Owner’s Manual (2014), the D40 Service Manual (Cooling System, section CO), and the Nissan Genuine Long Life Antifreeze/Coolant (Blue) Technical Data Sheet — specifies a liquid-cooled engine that relies on ethylene‑glycol coolant for temperature control, corrosion protection, and water‑pump lubrication.

For this ute, coolant does the heavy lifting under the bonnet. It pulls heat out of the engine, lifts the boiling point and drops the freezing point, and shields aluminium components (radiator, heater core, head) from internal corrosion and scale. It also keeps the water pump happy and the heater blowing warm on frosty mornings.

The recommended fill is Nissan Genuine Long Life Antifreeze/Coolant (Blue), typically a 50/50 pre‑mix with demineralised water. Don’t mix coolant types or colours — blending blue long‑life with universal green or red can slash service life and cause sludge. If a top‑up is needed in a pinch, use the same blue long‑life, very small amounts of demineralised water are acceptable to reach the mark.

Service-wise, owners should check the translucent reservoir when the engine is cold and keep the level between MIN and MAX. As a guide from Nissan materials: the factory fill often runs to about 160,000 km or 8 years, then subsequent changes every 5 years or 100,000 km. Heavy towing, outback heat, or stop‑start use? Test the coolant annually and replace sooner if protection is low or contamination is present. Always confirm the exact interval in the vehicle’s maintenance schedule.

• Inspect hoses, clamps, radiator cap, and the water pump area for crusty residue, staining, or that sweet coolant smell.
• Only open the radiator cap when stone cold. Hot systems are pressurised.
• During a change, drain, flush with demineralised water, refill with the correct mix, set the heater to HOT, and bleed air out. Many D40s bleed cleanly by idling with the cap off until the thermostat opens, some variants have a bleed screw near the upper hose or housing.
• After a short drive, recheck the reservoir next morning and top up to MAX if needed.
• Dispose of old coolant responsibly — it’s toxic to pets and wildlife.

System capacity varies by engine and spec, but expect roughly 9–11 litres, the exact figure is in the service manual. Sticking with the right blue long‑life coolant and a proper change schedule keeps the Navara running cool and protects expensive components for the long haul.

Popular questions

What coolant type does a 2014 Nissan Navara use?

The 2014 Navara uses Nissan Genuine Long Life Antifreeze/Coolant (Blue), an ethylene‑glycol, silicate‑free long‑life formulation suited to aluminium engines. Use a 50/50 mix (or pre‑mix) and avoid mixing different coolant colours or chemistries.

How often should the coolant be changed?

Nissan documentation commonly lists the factory fill at up to about 160,000 km or 8 years, then every 5 years or 100,000 km thereafter. Severe use (towing, high ambient temps, dusty work) justifies annual testing and earlier replacement if protection is marginal or the fluid looks off.

How do you bleed the cooling system after a flush?

With the engine cold, set the heater to HOT, fill the radiator slowly with the correct coolant, and fill the reservoir to MAX. Start and idle with the cap off until the thermostat opens and the level stabilises, topping up as needed. Some variants have a bleed screw near the upper hose—crack it to release air, then tighten. Fit the cap, drive, and recheck the reservoir next day when cold.
