2007 Nissan Pathfinder Oil Pump — What It Does and When to Service It

Yes, the 2007 Nissan Pathfinder is fitted with an engine oil pump. Technical sources that confirm this include the Nissan Pathfinder (R51) Factory Service Manual (2007), Lubrication (LU) and Engine Mechanical (EM) sections, which describe a crankshaft-driven trochoid/gerotor-type oil pump. The VQ40DE 4.0L petrol’s pump is integrated into the front cover and driven directly off the crank, while the YD25DDTi 2.5 diesel uses a front-mounted, crank/chain-driven rotor-type pump. Nissan’s parts catalogues for the R51 platform also list complete oil pump assemblies for these engines.

On this Pathfinder, the oil pump’s job is to push pressurised oil through the galleries, filter and (on the diesel) the turbo, keeping bearings, cams and timing chains happy. Proper oil pressure is what stops metal-to-metal contact, cuts wear, cools hot spots and carries away contaminants.

There’s no routine replacement interval for the oil pump itself
