Parts for your 2013 Nissan Serena-Sump plug washers

2013 Nissan Serena sump-plug-washers: what they do and when to replace them

Technical sources confirm that the 2013 Nissan Serena (C26 series) uses a replaceable sump plug washer. The Nissan C26 Serena Service Manual (Engine – Lubrication section) specifies a drain plug with a crush-type gasket, and the Nissan FAST electronic parts catalogue lists an M14 drain plug gasket commonly supplied as Nissan part number 11026-4N200 (also seen as 11026-01M02 on some markets). That means sump-plug-washers are relevant to servicing a 2013 Nissan Serena.

On this Serena, the sump plug washer (also called a drain plug gasket) is a small, soft metal ring—typically aluminium—that sits between the sump plug head and the oil pan. Its job is to deform slightly as the plug is tightened, creating a tight seal that keeps engine oil where it belongs. Without a good washer, the plug can seep, the threads can be over-tightened to “chase” a seal, and the sump face can be marked. A fresh washer lets the plug reach the correct clamping load at the proper torque.

Best practice for the 2013 Serena is to replace the washer at every oil change. Nissan crush washers are designed as single-use items, once compressed, they don’t spring back reliably. A new washer helps prevent weeping around the plug and supports consistent torqueing. Typical Nissan drain plug torque for M14 applications sits in the mid-30 N·m range, always follow the exact figure in the model’s service manual and use a torque wrench rather than “by feel.”

Owners and workshops looking after a C26 Serena (including S-HYBRID variants) should keep a small stash of correct-spec M14 aluminium washers on hand. Avoid reusing a visibly flattened, gouged or hardened washer, and swap it any time the plug is removed. After the first drive post-service, a quick look under the vehicle for any fresh oil around the plug is a smart move.

• Replace the washer at each oil change interval.
• Use the correct M14 Nissan-type crush washer (e.g., 11026-4N200).
• Tighten the plug to the service manual torque—don’t overdo it.
• Inspect for drips after the first heat cycle.

Popular questions about 2013 Nissan Serena sump-plug-washers

What size sump plug washer does the 2013 Nissan Serena use?
The C26 Serena uses a washer for an M14 drain plug. Nissan commonly specifies an aluminium crush washer such as 11026-4N200. Sticking with genuine or equivalent-spec aftermarket washers ensures the correct inner/outer diameters and thickness for a proper seal.

How often should the sump plug washer be replaced on a 2013 Serena?
It should be replaced every time the engine oil is changed. These are single-use crush washers, once compressed, they can’t guarantee the same seal a second time. Replacing it each service helps prevent leaks and avoids overtightening the plug.

Can the washer be reused if it looks fine?
Reusing is not recommended. Even if it looks tidy, the metal has already deformed. Reuse increases the risk of slow weeps and can tempt overtightening, which risks damaging the plug threads or the sump sealing face. A new washer is inexpensive protection.
