Parts for your 2013 Nissan Navara-Oil pump

2013 Nissan Navara oil pump — what it does and when to service or replace it

An oil pump is absolutely relevant and fitted to the 2013 Nissan Navara across its common engines (YD25DDTi 2.5 diesel, VQ40DE 4.0 petrol, and other market variants). Technical sources that document this include the Nissan D40 Factory Service Manual (Lubrication System section), which illustrates a trochoid-type oil pump integrated with the front cover and driven by the crankshaft, and the Nissan FAST electronic parts catalogue, which lists the oil pump assembly and related components (pickup, relief valve, gaskets) for 2013 Navara engines. Mainstream workshop manuals for the Navara/Pathfinder of the same era also cover oil pump operation, pressure specs, and removal/installation procedures, confirming its presence and serviceability.

On a 2013 Navara, the oil pump’s job is simple but critical: keep pressurised oil moving through the bearings, camshafts and timing hardware so the engine runs smoothly and lasts. It’s a positive-displacement trochoid pump designed to deliver the right pressure at idle and on the highway, while the relief valve prevents over-pressure. Without it, the engine would be toast in minutes.

The oil pump itself isn’t a routine replacement item, instead, good servicing keeps it healthy. Regular oil and filter changes at the intervals recommended for local conditions (often every 10,000–15,000 kilometres or 12 months in AU/NZ, sooner if towing, off-roading, or doing short trips) help prevent sludge and abrasive wear. Always use the correct specification oil viscosity for the engine and climate, and quality filters with proper anti-drainback valves.

Owners and workshops should watch for tell-tales of low oil pressure: warning lamp flicker at idle, top-end ticking, chain rattle on cold start, or a sudden increase in mechanical noise. If any of these show up, a mechanical gauge test is the first step. If pressure is genuinely low, inspect the pickup screen for blockage, check the pickup O-ring for air leaks, verify bearing clearances, and only then consider the pump.

When replacement is necessary, it’s a fair bit of spanner work. On many Navara engines the pump is housed in the front cover, so expect sump removal, front cover access, cleaning and resealing. Best practice includes: priming the new pump with fresh oil, renewing the pickup O-ring and gaskets, checking the pressure relief valve, using the correct sealant on the front cover, and torquing fasteners to the factory specs. After reassembly, crank with the injector or ignition disabled to build oil pressure before first start, then verify pressure with a gauge. Avoid hard revs from cold and keep up with timely oil services to maximise pump and engine life.

• Service tip: if the vehicle works hard (towing, hot climate, dusty tracks), shorten oil change intervals.
• Diagnostic tip: never rely solely on the dash lamp—confirm with a gauge.

How long does an oil pump last on a 2013 Navara?

With regular oil changes and quality filters, many Navara pumps run well past 250,000 kilometres. They’re robust, and most failures trace back to contaminated oil, sludge, blocked pickups, or general engine wear increasing clearances.

If the engine’s clean inside and oil pressure stays within spec, there’s usually no reason to replace the pump as routine maintenance.

What are the signs of a failing oil pump on a 2013 Navara?

Common red flags include a low oil pressure warning, ticking lifters, chain rattle on cold start, or a whirring/whining from the front cover. Metal sparkle in drained oil or the filter can also point to broader lubrication issues.

Confirm with an external gauge. If pressure is low, inspect the pickup and O-ring first, then assess bearing clearances before condemning the pump.

Can it be driven if the oil pressure light comes on?

No—stop the engine as soon as it’s safe. Running with low or no oil pressure can damage bearings, cam lobes, and the turbo on diesel models in very short order.

Have it towed, checked with a gauge, and repaired properly to avoid a costly rebuild.
