2005 Nissan Navara Oil Pump — What It Does and How to Look After It

Yes, a 2005 Nissan Navara uses an oil pump. Factory technical sources confirm it: the Nissan Navara D22 and D40 Service Manuals (Lubrication/Engine Mechanical sections) detail a crank-driven trochoid/gerotor oil pump integrated into the front cover on the YD25DDTi diesel and VQ40DE petrol engines. Nissan’s FAST parts catalogue also lists the oil pump assembly for 2005 Navara variants. So the oil-pump is very much relevant on this model, and it’s central to engine longevity.

The oil pump’s job is straightforward but critical: it pushes engine oil through galleries to lubricate bearings, camshafts, and timing components, and to help with cooling and hydraulic tensioners. On the YD25, consistent oil pressure keeps the timing chain tensioner happy
