Parts for your 2000 Nissan Navara-Coolant

2000 Nissan Navara Coolant — what it does and how to look after it

Coolant is definitely relevant and used on the 2000 Nissan Navara. The D22 Navara engines (petrol and diesel) are liquid-cooled, with a radiator, thermostat and water pump detailed in the Cooling System section of the Nissan D22 Factory Service Manual, and they’re specified to run ethylene‑glycol engine coolant (often referred to as Nissan Genuine Long Life Coolant). The owner’s manual and Nissan coolant specifications back this up, including guidance on concentration and service intervals.

On this ute, coolant pulls heat out of the engine, carries it to the radiator to be shed to the air, and guards the alloy and steel internals from corrosion and scale. It also raises the boiling point and lowers the freezing point, and helps prevent cavitation around the water pump. In short, it keeps temperatures stable and the inside of the cooling system healthy.

For everyday use, a 50/50 premix (or a concentrate mixed 50/50 with demineralised water) is the sweet spot. The 2000 Navara originally shipped with green Nissan Long Life Coolant (a silicate/phosphate hybrid). If sticking with green LLC, a typical change interval is every 2 years or 40,000 km, whichever comes first. Some owners convert to Nissan’s blue Super Long Life Coolant, if doing so, fully flush first and confirm compatibility for the specific engine variant. Always follow the service schedule in the owner’s manual or FSM for your engine code.

Under the bonnet, it pays to do quick checks between services:

• Check the reservoir level when cold, top up with the same type and colour only.
• Inspect hoses, clamps and the radiator cap, replace anything cracked, soft or leaking.
• Look for dried pink/green crust around joins or the water pump weep hole.

When replacing coolant, drain, flush until clear, then refill slowly. Turn the heater to hot, run the engine, and bleed air thoroughly (many D22 engines have a bleed point near the thermostat housing/top hose). Expect around 7–9 litres total system capacity depending on engine. Recheck the level after the first decent drive once it’s cooled.

Never mix unrelated coolant chemistries, don’t top up with tap water, and dispose of old coolant responsibly—ethylene glycol is toxic to people and pets.

Popular questions about 2000 Nissan Navara coolant

What coolant type suits a 2000 Nissan Navara?

Use an ethylene‑glycol, silicate/phosphate hybrid coolant equivalent to Nissan Genuine Long Life Coolant (green). A 50/50 premix is ideal for most climates in Australia and New Zealand. If converting to Nissan Super Long Life Coolant (blue), perform a complete flush first and don’t mix types.

How often should the coolant be changed?

With green Nissan LLC, plan on every 2 years or 40,000 km. If the system is switched to Nissan blue SLLC and the FSM for your engine allows it, intervals can be longer, but only after a proper flush. Always confirm against the service manual for your specific engine code.

How do you bleed the cooling system on a D22?

Fill slowly, set the heater to hot, start the engine and let it warm while gently squeezing the upper hose. Open the bleed screw if fitted to release trapped air, top up as bubbles dissipate, then cap it, bring to operating temp, and allow to cool before a final level check at the reservoir. Repeat if the heater blows cool or if the temp gauge fluctuates.
