Parts for your 2020 Nissan Pathfinder-Oil pump

2020 Nissan Pathfinder Oil Pump

Technical sources confirm the 2020 Nissan Pathfinder absolutely uses an oil pump. The Nissan Factory Service Manual (R52, 2017–2020), particularly the Engine Mechanical (EM) and Lubrication (LU) sections, outlines a chain-driven, variable-displacement oil pump integrated into the front timing cover on the VQ35DD 3.5‑litre V6. Nissan technical training material on the VQ engine family also details pressure-regulated, variable oil pumps for efficiency and valve timing control, so the oil pump is a core component on this model.

For this Pathfinder, the oil pump’s job is to feed pressurised oil to bearings, cam phasers and the valvetrain, keeping everything slick and cool while the ute hauls family and gear. Because the VQ35DD uses continuously variable valve timing, steady oil pressure is critical for smooth performance and fuel economy. The pump meters flow based on engine demand, reducing drag when cruising and ramping up under load.

It’s not a routine replacement item, but looking after it is still part of smart servicing. The best protection is timely oil and filter changes with the right spec oil (0W‑20 full synthetic is the usual call-out for this model—always follow the owner’s manual). Cheap filters without a solid anti‑drainback valve can starve the pump and valvetrain at start‑up, so quality matters.

• Watch for warning signs: low oil pressure light, rattly cold starts that don’t settle quickly, VVT-related fault codes, or persistent top-end ticking after fresh oil.
• If the sump’s off for other work, inspect the pickup and O‑ring for hardening or nicks
