Parts for your 2010 Nissan Navara-Oil pump

2010 Nissan Navara oil-pump — what it does and when to sort it

Short answer: yes, the 2010 Nissan Navara is fitted with an oil-pump. Technical sources including the Nissan Navara D40 Factory Service Manual (Lubrication System and Engine Mechanical sections), the Nissan Electronic Parts Catalogue (D40 listings for YD25DDTi and V9X engines), and common workshop data (Autodata/Haynes coverage for D40) all show a crankshaft-driven trochoid/gerotor oil-pump mounted in the front cover with a pickup strainer in the sump. That makes the oil-pump absolutely relevant on any 2010 Navara sold in Australia and New Zealand.

The oil-pump’s job is simple but critical: it pressurises and circulates engine oil so bearings, camshafts and turbocharger (on the diesels) stay lubricated and cooled. Without solid oil pressure, the top end ticks, the bottom end grumbles, and a good ute has a bad day.

As for servicing your 2010 Navara oil-pump, it’s not a routine replacement item. The best “maintenance” is timely oil and filter changes with the correct spec oil. For most AU/NZ conditions that means quality low-ash diesel oil (ACEA C3 5W-30 is commonly specified for YD25 and V9X) at sensible intervals (often 10,000 km, or as per your service schedule if in dusty/towing duty).

Watch for these warning signs:

• Oil pressure warning light at idle or on hot starts
• Top-end rattle on cold start that lingers
• Flickering oil light when cornering/braking hard
• Audible bearing rumble or turbo whine changes

If diagnostics show low oil pressure (verified with a mechanical gauge), consider more than just the pump: a clogged pickup strainer, a hardened pickup O-ring (known on some YD25s), worn bearings, or a sticking relief valve can all drop pressure. A competent tech will inspect the sump pickup, relief valve, and clearances before condemning the pump.

When replacement is due, use a quality pump and new seals. Priming matters: pack the pump with assembly lube or clean oil, prefill the filter, then crank with injectors disabled to build pressure before letting it fire. It’s smart to pair pump work with related front-cover or timing-chain work to save labour. After fitting, confirm hot-idle and 2,000 rpm pressure meets the FSM specs, and keep up the oil changes so the fresh pump lives a long, happy life under the bonnet.

Popular questions about 2010 Nissan Navara oil-pump

Does a 2010 Nissan Navara have an oil-pump?
Yes. All 2010 Navara D40 engines (including YD25DDTi 2.5 diesel and V9X 3.0 V6 diesel) use a crank-driven oil-pump, as shown in the Nissan D40 Factory Service Manual and Nissan Electronic Parts Catalogue.

How often should the oil-pump be replaced?
There’s no scheduled interval. It’s replaced on condition—typically after confirmed low oil pressure or internal wear. Regular oil and filter changes with the correct spec oil are the key preventative “service” for the oil-pump.

What are common symptoms of a failing oil-pump on a D40?
Low or flickering oil pressure light, extended top-end rattle on cold starts, and pressure readings below spec when checked with a mechanical gauge. Also check the sump pickup and O-ring, as issues there can mimic pump failure.
