Parts for your 2016 Nissan Serena-Sump plug washers

2016 Nissan Serena sump plug washers: what they do and when to replace

Yes, a sump plug washer is used on the 2016 Nissan Serena. Nissan’s C26 Serena service literature and the Nissan FAST parts catalogue specify a crush-type gasket on the engine oil drain (sump) plug. Nissan lists this as an oil drain plug gasket, commonly an M14 aluminium or copper washer such as 11026-01M02 or its later equivalent 11026-JA00A. That means sump plug washers are absolutely relevant to the 2016 Nissan Serena’s servicing.

The sump plug washer (also called a drain plug gasket) is a small, single-use seal that sits between the sump plug head and the oil pan. When the plug is tightened, the soft metal washer deforms to create a reliable, even seal. On the Serena, this helps prevent weeping around the plug, keeps oil where it should be, and allows the plug to be tightened to spec without chewing up the pan or relying on thread sealants. It’s a simple part that does a big job.

For routine servicing of a 2016 Nissan Serena, best practice is to replace the sump plug washer at every oil change. Reusing a crushed washer can lead to slow leaks, oil spots on the driveway, or a burnt-oil whiff after a highway run. If there’s any sign of seepage at the plug, the first fix is a fresh washer and a correct torque.

• Replace the washer at each service interval (typically every 10,000–15,000 km or 12 months, per local conditions and service schedule).
• Tighten the drain plug to the specification in the Serena’s service manual, many Nissan M14 plugs sit in the ~30–40 N·m range. Don’t overdo it—let the new washer do the sealing.
• Clean the mating face on the sump, and inspect the plug. If the plug’s flange is scored or the threads are tired, replace the plug as well.
• Use a quality OEM-equivalent M14 crush washer (aluminium or copper). Keeping a few spares in the toolbox saves hassle.
• Dispose of used oil and the old washer responsibly at a recycling centre.

This small part keeps the Serena’s sump tidy, the service neat, and helps the family bus stay leak-free between changes—easy win.

Popular questions related to 2016 Nissan Serena sump plug washers

What size sump plug washer does a 2016 Nissan Serena use?
Most 2016 Serenas use an M14 crush washer on the engine oil drain plug. Nissan commonly supplies 11026-01M02 or 11026-JA00A. Always check against the VIN or existing plug before ordering.

How often should the sump plug washer be replaced?
Replace it at every oil change. It’s a single-use crush washer, once compressed, it won’t seal as reliably a second time. Fresh oil, fresh filter, fresh washer—job done.

Can the washer be reused if it looks fine?
It’s not recommended. Even if it looks okay, the metal has already deformed. Reusing increases the risk of weeping or needing extra torque on the plug, which isn’t great for the sump.
