Parts for your 2011 Honda Elysion-Sump plug washers

2011 Honda Elysion sump plug washers

For the 2011 Honda Elysion, a sump plug washer (also called an oil drain plug crush washer) is indeed used and relevant. Honda factory literature for comparable K24A and J‑series V6 engines of the same era instructs refitting the drain bolt with a new washer at each oil change, and the parts catalogue lists a 14 mm aluminium crush washer for the drain plug. Workshop procedures in Honda service manuals for these engines specify replacing the “drain bolt gasket/washer” during engine oil servicing, confirming the Elysion follows the same design practice.

The sump plug washer on a 2011 Honda Elysion is a small, single-use aluminium crush washer that sits under the drain plug and seals the sump. Its job is simple but crucial: when the drain plug is torqued, the soft washer deforms slightly to seal any tiny imperfections between the plug and the sump, preventing annoying drips and messy driveways. On Hondas of this generation, it’s a standard bit of kit—cheap, reliable, and designed to be replaced whenever the engine oil is changed.

As part of routine servicing on an Elysion—whether it’s the 2.4-litre four or the V6—best practice is to install a new washer every time the oil is drained. Reusing an old one can lead to seepage, gradually loosening torque, and the kind of slow leak that’s easy to miss until the level drops. The typical Honda torque spec for the drain plug is around 39 N·m (29 lb‑ft), a fresh crush washer helps the plug reach correct clamping force without over-tightening.

Techs and home mechanics across Australia and New Zealand will usually keep a few 14 mm Honda-style aluminium washers on hand, as they’re inexpensive. If a copper or reusable washer is being considered, it’s worth noting Honda’s own literature specifies a single-use aluminium type for reliable sealing. Swapping like-for-like avoids guesswork.

• Always clean the sealing face on the sump and the drain plug before refitting.
• Fit a new 14 mm aluminium crush washer, flat side against the sump, and torque the plug correctly.
• After the first heat cycle, check for any sign of weeping around the plug.

With that done, the Elysion stays tidy underneath, oil stays where it should, and servicing remains straightforward.

Popular questions

What size sump plug washer does the 2011 Honda Elysion use?

It uses a 14 mm aluminium crush washer designed for Honda drain plugs. This single-use washer deforms under torque to create a proper seal between the plug and the sump.

How often should the sump plug washer be replaced on an Elysion?

Replace it at every engine oil change. Honda service guidance for the same engine families specifies a new drain plug washer each time the oil is drained to ensure a reliable seal and correct torque.

Can a copper or reusable washer be used instead?

Honda specifies a single-use aluminium washer. While copper can seal in some cases, sticking with the correct aluminium crush washer avoids variability in sealing and torque feel, and aligns with factory servicing practice.
