Parts for your 2010 Nissan Navara-Radiator

2010 Nissan Navara Radiator — what it does and how to look after it

Yes, a radiator is absolutely fitted to the 2010 Nissan Navara (D40). Technical references including the Nissan Navara D40 Service Manual (2010, Cooling System “CO” section), the Nissan genuine parts catalogue for D40, and popular workshop manuals confirm an aluminium crossflow radiator across diesel and petrol variants, with an integrated transmission cooler on most automatic models. So this part is very much relevant to the ute.

The radiator’s job is to shed engine heat from the coolant, keeping the Navara happy whether it’s crawling a job site, towing the boat, or punching into a Nor’wester. Coolant circulates through the engine, picks up heat, then runs through the radiator’s fine tubes and fins where airflow and the fan dump that heat to the breeze. On autos, the built-in cooler also helps manage transmission temperatures.

For a 2010 Navara, smart servicing keeps the cooling system reliable:

• Inspect at every service: look for crusty pink/white staining at end-tanks, damp spots around the core, soft or swollen hoses, and a tired cap seal.
• Coolant quality: use the correct long-life coolant that meets Nissan specifications, top up only with premix or demineralised water and concentrate mixed to spec.
• Intervals: long-life coolant is typically replaced about every 5 years or up to 120–150,000 km, with annual checks and earlier changes if the coolant looks dirty or tests weak. Follow the service schedule for your engine variant.
• Bleeding: after a drain and refill, run the heater, bleed air at the designated points, and recheck the level once cooled.
• Airflow: clear bugs and seeds from the fins with gentle hose pressure from engine side out. Don’t bend the fins with high pressure.

Replacement is straightforward with the right prep. Choose an OEM-quality radiator, renew the cap, upper and lower hoses, clamps, and thermostat while you’re there. On automatic models, inspect the built-in trans cooler lines and consider an auxiliary cooler if towing heavy in hot conditions. Watch for signs of trouble like a rising temp gauge under load, a sweet coolant smell, frequent top-ups, brown sludge, or a heater that’s gone cold—sort issues early to avoid a cooked head or mixed coolant/ATF dramas.

Backed by Nissan’s D40 service literature and parts data, keeping the radiator and coolant in good nick is cheap insurance for a hard-working Navara.

Popular questions

What coolant does a 2010 Navara use, and how much does it take?
Nissan specifies a long-life ethylene glycol coolant that meets its D40 requirements. Capacity varies by engine and heater spec, but most YD25 diesel models sit around the 9–10 litre mark. Always check the owner’s or service manual, and don’t mix coolant types—stick with one spec and brand if possible.

How often should the coolant be changed on a 2010 Navara?
For long-life coolant, plan on about every 5 years or 120–150,000 km, with annual inspections for level, colour, and protection strength. If the vehicle has unknown history, tow work, or signs of contamination, change it sooner and flush properly.

Is the stock radiator OK for towing?
If the cooling system is healthy and clean, the factory radiator is fine for normal towing within the ute’s rated limits. Keep fins clear, coolant fresh, and hoses and cap in good order. For frequent heavy towing in high ambient temps, many owners add an auxiliary transmission cooler (autos) and ensure the radiator is OEM quality.
