Parts for your 2016 Nissan Pathfinder-Sump plug washers

2016 Nissan Pathfinder sump plug washers

Referencing Nissan’s own technical literature, the 2016 Nissan Pathfinder (R52, VQ35DE) does use a sump plug washer (also called an oil drain plug gasket). The 2016 Pathfinder Factory Service Manual (sections MA – Maintenance and LU – Lubrication System) calls for replacing the drain plug gasket whenever the plug is removed and specifies tightening the plug to about 34 N·m (25 ft‑lb). Nissan’s Electronic Parts Catalog for the R52 lists the oil drain plug gasket as an aluminium crush type, commonly supplied under Nissan part number 11026‑JA00A (superseding older 11026‑01M02) for a 14 mm plug. That makes sump plug washers directly relevant to servicing this model.

For the 2016 Pathfinder, the sump plug washer does a simple but critical job: it seals the drain plug to the alloy sump so engine oil doesn’t creep out over time. The washer is soft aluminium designed to “crush” slightly as the plug is torqued, filling any tiny imperfections between the plug flange and the sump face. That single‑use crush is why Nissan tells techs to fit a fresh washer at every oil change. Reusing a flattened washer is a false economy — it’s a common cause of weeps that leave spots on the driveway and can eventually drop oil level.

Owners who service their own Pathfinder will find the washer inexpensive and easy to swap. After draining the oil, wipe the sump face clean, fit a new 14 mm aluminium crush gasket to the plug, and tighten to around 34 N·m (25 ft‑lb) as per the FSM. Avoid overtightening — going gorilla‑tight can distort the washer, mark the sump face, or strip threads. If the old washer seems stuck to the sump, carefully peel it off without scratching the surface.

• Replace the washer every time the drain plug is removed.
• Check for tell‑tale weeping after a service, a quick nip to spec can tidy up a minor seep, but don’t exceed torque.
• Use the correct aluminium crush type, copper or fibre substitutes may not seal as predictably on this engine.
• If in doubt on sizing or part numbers, confirm by VIN through a Nissan parts desk.

Looked after this way, the sump plug and washer combo will stay leak‑free between services, keeping the 3.5‑litre V6 happy and the garage floor clean.

Popular questions about 2016 Nissan Pathfinder sump plug washers

What size and part number washer does the 2016 Pathfinder use?
The 2016 Pathfinder typically uses a 14 mm aluminium crush gasket, commonly supplied as Nissan 11026‑JA00A (which supersedes 11026‑01M02 in many catalogues). Because trim and regional supply can vary, it’s smart to confirm by VIN with a Nissan dealer before buying in bulk.

How often should the sump plug washer be replaced?
Every oil change. The washer is designed to deform once to create a perfect seal. Reusing it risks weeping, especially after long, hot runs common in Aussie and Kiwi summers. A fresh gasket each time is cheap insurance against leaks.

What is the correct torque for the drain plug on the 2016 Pathfinder?
Nissan’s service manual calls for about 34 N·m (25 ft‑lb). That’s firm but not excessive. Using a torque wrench helps avoid over‑crushing the washer or damaging sump threads, both of which can lead to leaks or costly repairs.
