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
