Parts for your 2013 Honda Elysion-Sump plug washers

2013 Honda Elysion sump plug washers

Based on Honda workshop literature for the Elysion’s K24 and J-series V6 engines, and aligned service manuals from the same era (e.g., Odyssey/Accord), the 2013 Honda Elysion uses a single-use aluminium crush washer on the engine oil drain (sump) plug. These manuals specify “always replace the drain plug washer” at each engine oil service and list a 14 mm aluminium sealing washer (commonly Honda P/N 94109-14000), with typical drain bolt torque around 39 N·m. So yes — a sump plug washer is relevant and fitted to this vehicle.

On this Elysion, the sump plug washer is a simple but crucial seal. When the drain bolt is tightened, the soft aluminium washer deforms to match the mating surfaces, creating a reliable seal that prevents weeping or drips after an oil change. Without that controlled crush, or if a flattened old washer is reused, tiny gaps can form and oil can wander out under heat and vibration — messy on the driveway and not great for the engine either.

As part of regular servicing, the washer should be replaced every oil change. It’s inexpensive, designed as single-use, and swapping it takes seconds while the oil is already drained. After refitting the bolt with a fresh washer, tighten to the specified torque (around 39 N·m for many Honda alloy sumps, check the exact spec for the Elysion’s engine variant). Over-tightening can distort the pan threads or the washer, under-tightening can allow a slow leak. A new OEM-style aluminium washer is the safe bet for correct crush and sealing.

• Always clean the sump face and drain bolt before refitting.
• Use a new 14 mm aluminium crush washer each service, avoid reusing the old one.
• Don’t stack washers or add sealants — the crush washer does the sealing.
• After the first drive, have a quick look underneath for any misting or drips.

For owners doing DIY servicing across Australia and New Zealand, keeping a small pack of genuine-style washers on the shelf makes life easy. It’s a tiny part that saves a lot of hassle — and keeps the Elysion tidy and leak-free between services.

Popular questions

What size sump plug washer does the 2013 Honda Elysion use?
The Elysion typically uses a 14 mm aluminium crush washer on the engine oil drain plug, matching common Honda specifications of the period. This size suits the drain bolt’s sealing face and provides the correct crush when torqued. Using the proper 14 mm washer helps avoid leaks and ensures consistent clamping.

How often should the sump plug washer be replaced on an Elysion?
Replace it at every oil change. Honda service information calls for a new washer each time the drain bolt is removed. The washer is designed to deform once, reusing it risks weeping, especially after a few heat cycles. Given the low cost, it’s sensible preventative maintenance.

Can a copper or reusable washer be used instead of aluminium?
While copper can seal, Honda specifies an aluminium crush washer for correct deformation and torque feel on the Elysion’s sump. Reusable or hard washers may not crush properly and could require different torque or surface prep. For straightforward, reliable sealing, stick with the Honda-style aluminium washer.
