Parts for your 2017 Nissan Navara-Oil pump

2017 Nissan Navara oil pump — what it does and how to look after it

Yes, the 2017 Nissan Navara is fitted with an engine oil pump. Technical references that confirm this include the Nissan D23 Series Navara Service Manual (Lubrication System and Engine Mechanical sections), which details a crankshaft-driven trochoid/gerotor oil pump integrated in the front cover on the 2.3‑litre YS23 diesel, and the Nissan Electronic Parts Catalogue for D23 models, which lists the oil pump assembly for 2015–2019 vehicles. Reputable workshop databases (e.g., Autodata and HaynesPro) also carry oil‑pump pressure specs and replacement procedures for the YS23 engine used in AU/NZ Navaras.

On the 2017 Navara, the oil pump’s job is to push the right amount of clean oil through the engine under pressure, so bearings, camshafts, timing components and the turbo(s) all stay lubricated and cool. It also feeds hydraulic chain tensioners. Without good pump performance, the engine can suffer noisy starts, bearing damage, timing rattle, or turbo failures, and the low‑oil‑pressure lamp can flick on—often at idle when hot.

Oil pumps usually last the life of the engine if serviced right, so the best “maintenance” is sticking to quality oil and filter changes at the interval in the service schedule (many owners in local conditions choose 10,000–20,000 km depending on use). Use the correct low‑SAPs diesel oil grade specified in the owner’s manual, especially with DPF‑equipped models.

Replacement is only recommended when there’s a verified fault. Typical clues include a persistent low‑pressure warning, rumbling bearings, chain rattle, metallic debris in the sump, or pressure readings below spec when measured with a mechanical gauge. Before condemning the pump, a good tech will check oil level and grade, the pick‑up strainer for sludge, the pressure relief valve, and for internal leaks (e.g., worn bearings).

• If the pump needs doing, expect front cover removal on YS23 engines—plan for new seals, RTV where specified, and a fresh pick‑up O‑ring.
• Always prime the pump with clean oil and pre‑lube the galleries. Crank with injectors disabled to build pressure before first start.
• After any pump or front‑cover work, fit a new filter, refill with the correct oil, and confirm hot idle and 2,000 rpm pressure meet spec on a gauge.
• Given the labour and timing‑chain proximity, it’s a job best handled by an experienced workshop.

Look after the oil system and the Navara’s pump will quietly keep things spinning for hundreds of thousands of kilometres.

FAQ: What are the symptoms of a failing oil pump on a 2017 Navara?

Common signs include the low‑oil‑pressure warning at idle when hot, rattly timing noises, increased lifter/tappet noise, and turbo whine or smoke from lack of lubrication. Verified low pressure on a mechanical gauge is the proper diagnostic step—don’t rely on the dash lamp alone.

FAQ: Should the oil pump be replaced as routine maintenance?

No. It isn’t a scheduled replacement item. With the right oil and filter changes, the factory pump typically lasts the life of the engine. Replace it only if testing shows it’s out of spec, or if there’s damage or heavy wear discovered during engine work.

FAQ: Can it be driven with the low oil pressure light on?

Best not. Stop the engine as soon as it’s safe. Driving on with low pressure can quickly damage bearings, the camshaft, and the turbo(s). Check the oil level and quality, and have pressure tested with a mechanical gauge before restarting.
