Parts for your 2019 Nissan Pathfinder-Oil pump

2019 Nissan Pathfinder oil-pump — purpose, care and when to replace

Yes, the 2019 Nissan Pathfinder absolutely uses an engine oil pump. Technical sources including the Nissan Factory Service Manual for the R52 Pathfinder (VQ35DD) — sections LU (Lubrication System) and EM (Engine Mechanical) — describe a crankshaft-driven trochoid oil pump integrated with the front timing cover. Nissan’s parts catalogue for the R52 likewise lists the oil pump/front cover assembly, and workshop databases such as Autodata/Haynes detail oil-pressure specs that rely on this pump’s operation.

On this V6, the oil pump’s job is to draw oil from the sump through the pickup and push it under pressure to bearings, camshafts, the timing-chain tensioners and the variable valve timing hardware. It keeps metal from touching metal, whisks away heat, and carries contaminants to the filter. Given the VQ35DD’s direct injection and chain-driven cams, steady oil pressure is vital for quiet starts, clean performance and long life — especially in Aussie and Kiwi conditions with towing, heat and long highway stints.

It’s not a regular replacement item, but looking after it is all about good lubrication habits:

• Service on time per the schedule (typically 10,000–15,000 km or 12 months, whichever comes first, depending on usage).
• Use the viscosity and spec in the owner’s manual (commonly 0W-20 for the VQ35DD in AU/NZ markets) and a quality filter.
• Keep an eye on the oil-pressure warning lamp and investigate any start-up rattle, ticking, or low-pressure messages promptly.
• Inspect for leaks around the front cover area and at the sump, low oil level will starve the pump.

When would a pump need replacement? Consider it if a verified low oil-pressure condition exists (checked with a mechanical gauge), there’s metallic debris in the sump, the timing chain tensioners won’t hold pressure, or the engine has severe sludge history. The job is involved: the front cover must come off, meaning the right engine mount, crank pulley and timing chains come out. Good practice includes cleaning the pickup screen, flushing the galleries, fitting new seals and a filter, priming the pump with clean oil before first start, and using the correct anaerobic sealant on the front cover. It’s a solid driveway project for pros, for everyone else, it’s best left to a workshop with the proper locking tools and torque specs. Treat it well and the Pathfinder’s pump is built to go the distance.

Popular questions

Does the 2019 Pathfinder have an oil pump and where is it?
Yes. It’s a crankshaft-driven trochoid pump integrated into the front timing cover on the VQ35DD engine. It draws oil from the sump and pushes it through the galleries, filter and cooler, then out to bearings, cams and timing-chain tensioners.

What are the signs of a failing oil pump on a 2019 Pathfinder?
Red oil-pressure warning lamp, verified low pressure at hot idle, start-up rattles from the timing chains, lifter/cam noise, or bearing knock. Always rule out low oil level, a blocked filter, thin/incorrect oil and wiring or sensor faults before condemning the pump.

Should the oil pump be replaced as preventative maintenance?
Normally, no. With regular oil and filter changes using the correct spec oil, the pump should last the life of the engine. Preventative replacement is only considered if the front cover is already off for major timing work on a very high-kilometre engine or there’s evidence of sludge or wear.
