Parts for your 2014 Nissan Navara-Oil pump

2014 Nissan Navara oil pump — what it does, why it matters, and when to sort it

Yes — the 2014 Nissan Navara is fitted with an engine oil pump. Nissan’s own technical publications confirm it: the Navara D40 Service Manual (LC: Lubrication System, 2010–2014) details a crank-driven trochoid/gerotor pump mounted in the front timing cover on YD25DDTi (2.5 diesel), QR25DE (2.5 petrol) and VQ40DE (4.0 petrol) engines. The Nissan FAST parts catalogue and dealer microfiche list the complete pump assembly, pickup and relief components for these engines, and independent data services (e.g., Autodata and Haynes) describe identical lubrication layouts.

On a 2014 Navara, the oil pump is the heart of the lubrication system. It draws oil from the sump through a screened pickup, pressurises it, and feeds crankshaft and cam bearings, turbocharger bearings (on diesels), timing chain tensioners and the valvetrain. Being driven off the crank, it scales pressure with engine speed, while an internal relief valve limits maximum pressure. Without a healthy pump, bearings starve, chains rattle and turbos can fail in short order.

There’s no routine replacement interval for the pump itself — it’s designed to last the life of the engine — but good servicing protects it. Stick to the correct oil spec and change intervals for Aussie/NZ conditions, use quality filters, and keep an eye on any oil pressure warning light or unusual noises. If the sump’s ever off, it’s smart to clean the pickup strainer and replace the pickup O-ring
