Parts for your 2018 Nissan Pathfinder-Oil pump

2018 Nissan Pathfinder oil pump

The 2018 Nissan Pathfinder (R52, 3.5‑litre VQ35DD petrol) is fitted with an engine oil pump. Technical sources confirming this include the Nissan Factory Service Manual (R52) in the LU – Lubrication System section, which diagrams a crankshaft-driven gerotor/“trochoid” oil pump integrated into the front timing cover, and the Nissan electronic parts catalogue (FAST), which lists the oil pump assembly and related gaskets/seals for the VQ35DD. So yes—an oil pump is relevant and used on this model.

On this Pathfinder, the oil pump’s whole job is to keep the V6 happily lubricated. It pulls oil from the sump and pushes it under pressure through the filter and galleries to crank and cam bearings, timing chains, and valve gear. With the VQ35DD’s variable valve timing and tight clearances, stable oil pressure is vital for smooth starts, quiet running and long engine life.

It isn’t a regular “service item” like filters or spark plugs, but looking after it is straightforward: use quality oil in the grade specified in the owner’s manual (often 0W‑20 for VQ35DD, some workshops in hotter Aussie and Kiwi climates prefer 5W‑30—follow Nissan’s guidance), change oil and filter on time, and keep an eye out for leaks. Fresh, clean oil helps the pump maintain pressure and reduces wear on its internal rotors and relief valve.

Signs the pump or the lubrication system needs attention include a low oil pressure warning, rattly timing chains at start‑up, ticking from the top end, metallic glitter in the drained oil, or rising engine temps under load. Before blaming the pump, a good tech will check oil level and condition, verify the correct filter is fitted, inspect for front cover leaks, and test actual oil pressure with a gauge.

Replacement is uncommon but sometimes necessary after severe sludge, debris ingestion, or high‑kilometre wear. On the VQ35DD it’s a decent job: the front timing cover comes off, the pump is removed from the cover, and sealing surfaces are cleaned and resealed. Best practice is to replace associated seals, inspect the pickup and chain, and prime the new pump with clean oil before first start. Torque specs and sealant bead patterns matter here—follow the Nissan FSM to the letter. If the warning light ever comes on while driving, stop the vehicle promptly, switch off under the bonnet, and arrange a tow, running with low pressure can quickly damage bearings and the timing system.

• Best habits: timely oil changes, correct viscosity, genuine‑quality filters, and quick response to leaks or warning lights.
• When to book in: persistent start‑up rattle, low‑pressure warnings, or verified low pressure on a mechanical gauge.

Does the 2018 Pathfinder have an oil pump?

Yes. The VQ35DD engine uses a crankshaft‑driven gerotor oil pump housed in the front timing cover. This is documented in the Nissan Factory Service Manual (R52) under LU – Lubrication System, and shown in the Nissan FAST parts catalogue.

How long does the oil pump typically last?

With regular servicing and the correct oil, the factory pump commonly lasts the life of the engine. Failures are uncommon and usually tied to sludge, contamination, incorrect oil, or extended running with low oil level.

What are the warning signs of a failing oil pump on a Pathfinder?

Low oil pressure warnings, chain rattle on cold start, top‑end ticking, or hotter‑than‑normal running. Always verify with a mechanical pressure test and rule out basics like low oil level, a clogged filter, or leaks at the front cover.
