Parts for your 2009 Honda Elysion-Sump plug washers

2009 Honda Elysion sump plug washers

Yes, the 2009 Honda Elysion uses a sump plug washer. Technical references include the Honda Elysion service manual (KA1/KA2/KA3, Lubrication System – Engine Oil Replacement), which specifies to “always use a new drain plug washer” and to torque the drain bolt to 39 N·m (29 lbf·ft). Honda parts catalogues list a 14 mm crush-type drain plug washer for the K24A 2.4 and J30A V6 engines, commonly supplied under Honda part numbers 90471-PX4-000 (aluminium) or 94109-14000 (14 mm). That makes sump-plug-washers absolutely relevant on this model.

On the 2009 Honda Elysion, the sump-plug-washer (drain plug gasket) is a small, single-use crush washer that sits between the oil pan and the drain bolt. Its job is to deform slightly as the bolt is tightened, creating an even, oil-tight seal across the mating surfaces. That controlled “crush” helps prevent drips, weeping, and loosening due to heat cycling and vibration—handy on long Kiwi and Aussie road trips where engines get a proper workout.

Honda’s own servicing guidance is to replace the washer at every oil change. Reusing a crushed washer can cause slow leaks, rounded torque feel, or the temptation to over-tighten the bolt to chase a seal—risking stripped threads in the alloy sump. The correct approach is simple: install a fresh 14 mm Honda-spec aluminium (or copper) washer, clean both mating faces, and torque the drain bolt to 39 N·m. No sealants, no PTFE tape, and definitely no stacking of old washers.

Aluminium washers are the go-to for most Hondas of this era because they crush consistently and come off cleanly. Copper types exist and can also work, but the key is using the correct 14 mm inner diameter and sticking with OEM-quality parts. If there’s any scoring on the pan face or the bolt flange, replace the bolt too—it’s cheap insurance.

Signs a new washer is overdue include a faint oil halo around the plug, a drip on the driveway after a night parked, or a plug that never quite feels “right” at the wrench. As part of a tidy service on an Elysion, a fresh filter, the correct grade of oil, and a new sump-plug-washer will keep the K24A or J30A happy, leak-free, and easy to service next time around.

• Washer type/size: 14 mm crush washer (Honda OE spec)

Popular questions

What size sump plug washer does a 2009 Honda Elysion use?
The Elysion uses a 14 mm crush washer on the engine oil drain plug. Honda commonly supplies this as an aluminium washer under part numbers such as 90471-PX4-000 or a 14 mm drain plug gasket listed as 94109-14000. Using the correct 14 mm ID ensures it centres accurately and crushes as intended.

What’s the correct torque for the sump plug on a 2009 Elysion?
The factory torque is 39 N·m (29 lbf·ft). Tighten with a torque wrench on a clean, dry seat using a new crush washer. Over-tightening won’t improve sealing and risks damaging the sump threads, the washer is what does the sealing, not brute force.

Can the sump plug washer be reused?
It’s designed as a single-use crush washer and should be replaced at every oil change. Reusing it can cause weeping leaks or inconsistent clamp load, making future removal harder. Keep a few spares on hand so every service is leak-free and hassle-free.
