Parts for your 2013 Nissan Pathfinder-Oil pump

2013 Nissan Pathfinder oil pump — what it does and when to service it

Based on technical sources, the 2013 Nissan Pathfinder is absolutely fitted with an engine oil pump. The Nissan Factory Service Manual (R52, 2013) in the LU – Lubrication System section, and Nissan’s Electronic Parts Catalogue for the VQ35DE 3.5‑litre petrol and QR25DER hybrid engines, both show a chain/crank-driven trochoid/gerotor oil pump integrated into the front (timing) cover with a built-in pressure relief valve. So yes, the oil pump is relevant to this model.

On this Pathfinder, the oil pump’s whole job is to move the right amount of oil, at the right pressure, through the engine. That keeps bearings, camshafts and timing components lubricated and cooled, and it feeds the valve timing system too. Without stable pressure, you’ll get extra wear, noisy starts, possible timing control faults, and in the worst case, engine damage. It’s a quiet hero under the bonnet.

There’s no routine “replace by X kilometres” interval for the pump itself. Instead, it lives or dies by oil quality and level. Sticking to the correct oil grade and the logbook service schedule, using a quality filter, and checking the level regularly will do more for pump life than anything else. If the low oil pressure warning flickers, there’s top-end rattle on hot idle, or you find metallic debris at oil changes, don’t keep driving—get a mechanical oil pressure test done. If pressure is out of spec after ruling out low oil, a blocked pickup, or a dud pressure switch, the pump may be due.

If replacement is needed, it’s a front cover–integrated unit, so it’s a fairly involved job: crank pulley off, timing cover off, and timing components disturbed. It’s best left to a workshop. Smart techs will: inspect the pickup strainer and O‑ring, check chain wear and guides, clean or verify the relief valve, use the correct sealant pattern on the front cover, and prime the pump with clean oil before first start. They’ll also verify hot idle and raised‑rpm pressure with a gauge once it’s back together.

• Watch for warning lamp flicker, timing control faults, or new engine noise.
• Use the correct viscosity oil and change it on time—especially important on the hybrid QR25DER with frequent stop/start.
• Never drive with a low oil pressure warning—shut it down and diagnose.
