Parts for your 2016 Nissan Navara-Oil pump

2016 Nissan Navara oil pump — what it does and when to service or replace it

Yes, the 2016 Nissan Navara (D23/NP300) uses an engine oil pump. All Australian and New Zealand 2.3‑litre YS23 diesel variants (single‑ and twin‑turbo) are fitted with a crank‑driven pump mounted in the timing cover. This is documented in the Nissan Navara D23 Series Service Manual (Engine – Lubrication System) and shown in the Nissan Electronic Parts Catalogue, which lists an “Oil Pump Assy” for YS23DDT and YS23DDTT engines. Genuine and aftermarket parts catalogues for this model also list replacement oil pump assemblies and pick‑ups, confirming it’s a standard component on the 2016 ute.

On this Navara, the oil pump is the heart of the lubrication system. It draws oil from the sump, pushes it through the filter, and feeds critical parts such as crank and cam bearings, timing chains, and the turbocharger(s). It also helps cool and clean the engine by carrying heat and contaminants away to the cooler and filter. Without steady pressure, the YS23’s turbo and bearings won’t last long, so keeping the pump and its oil supply in top nick is essential.

The oil pump itself isn’t a routine service item, it’s replaced when there’s confirmed low oil pressure or internal wear. Before blaming the pump, a good workshop will verify pressure with a mechanical gauge and rule out thin/old oil, a blocked filter, a torn pick‑up O‑ring, sludge at the strainer, or excessive bearing clearances.

• Common red flags owners notice: low oil pressure warning, rattly timing/knock on cold start, turbo whine, metal flecks in the oil, or persistent top‑end noise.
• If replacement is needed: expect sump removal, timing cover off, new front crank seal, new pick‑up O‑ring, careful RTV sealing, and pump priming with clean oil before start‑up.

As part of normal servicing, the best way to look after the oil pump is to look after the oil. Stick to the service schedule in the owner’s manual, use the correct low‑SAPS diesel oil (ACEA C‑spec, typically 5W‑30) and a quality filter, and shorten intervals if the ute tows, idles, or works in dusty or hot conditions. Let it idle briefly after heavy towing to look after the turbos and avoid aggressive engine flushes that can dislodge sludge into the pick‑up.

With proper oil and filters, the Navara’s pump generally lasts the life of the engine in Aussie and Kiwi conditions. When it’s time, use quality parts and proper priming so the fresh pump builds pressure straight away—no dramas.

Popular questions

Does a 2016 Nissan Navara have an oil pump?
Yes. All 2016 D23/NP300 Navara diesels in Australia and New Zealand use a crank‑driven oil pump in the timing cover. This is shown in the D23 Service Manual’s lubrication section and in OEM parts catalogues.

When should the oil pump be replaced on a 2016 Navara?
It’s not a scheduled item. Replace it only after confirmed low oil pressure or internal wear. Always verify with a mechanical gauge and check the oil grade, filter, pick‑up O‑ring, and clearances first.

What are the signs of a failing oil pump?
A lit oil pressure warning, top‑end ticking, timing chain rattle on start‑up, turbo noise, or metal in the oil are red flags. Get it diagnosed promptly—continuing to drive can cause major engine damage.
