Parts for your 2012 Nissan Navara-Oil pump

2012 Nissan Navara oil pump — what it does and how to look after it

Based on Nissan’s own technical literature, the 2012 Navara (D40) absolutely uses an engine oil pump. The Nissan Navara D40 Service Manual (Lubrication System section), the Nissan FAST parts catalogue (listing complete oil pump assemblies for YD25DDTi, V9X and VQ40DE engines), and the V9X/YD25 engine workshop manuals all describe a crankshaft-driven, gear/trochoid-type oil pump, its relief valve, pick-up, and priming procedures. So the oil pump is relevant and fitted to all 2012 Navara engines.

In a 2012 Nissan Navara, the oil pump is the heartbeat of the engine’s lubrication system. Spun directly by the crank, it pulls oil through the pick-up strainer and pushes it under pressure through galleries to crank and cam bearings, timing components, and (on diesels) the turbocharger. That pressurised flow builds the protective oil film that stops metal-to-metal contact, manages heat, and sweeps away contaminants to the filter. Without a healthy pump and clean oil, bearings score, chains rattle, and turbos can suffer a short, unhappy life.

The Navara’s pump is designed to be tough and low-maintenance, but it depends on good oil and regular servicing. It’s not a “replace every X kilometres” item
