Parts for your 2014 Honda Accord-Sump plug washers

2014 Honda Accord sump-plug-washers — what they do and when to change them

Yes, the 2014 Honda Accord uses a sump plug washer. Honda’s factory service information for the 2013–2017 Accord specifies installing the engine oil drain bolt with a new 14 mm aluminium crush washer and tightening to 39 N·m (29 lbf·ft). The Owner’s Manual reinforces using a new washer at each oil change, and Honda’s genuine parts catalogue lists the washer as 94109-14000 (or superseding equivalent). Those technical sources make it clear: a sump-plug-washer is absolutely relevant on this model.

What does the washer actually do? It’s a soft aluminium ring that deforms slightly (crushes) as the drain bolt is torqued, sealing the mating faces between the bolt and the sump. That controlled crush prevents weeping, helps maintain correct torque, and protects the alloy sump threads from over-tightening. Without a good washer, tiny paths for oil can open up, leading to drips on the driveway and a mess under the car.

For anyone servicing a 2014-honda-accord, the sump-plug-washers are treated as single-use consumables. Swapping in a fresh washer at every oil change is cheap insurance. Reusing an old one can feel fine on the spanner, but once a crush washer has done its job, it won’t reliably reseal the next time.

Good practice for sump-plug-washers replacement on a 2014 Accord:

• Use the correct size: 14 mm aluminium crush washer (Honda p/n 94109-14000 or equivalent).
• Clean the sump’s sealing face and the drain bolt head so the new washer sits flat.
• Never stack washers or mix types (aluminium vs copper vs bonded). Stick with the specified style.
• Refit and torque the drain bolt to 39 N·m (29 lbf·ft) — no rattle-gun heroics.
• After warm-up, check for a faint weep. If there’s any sign, replace the washer and re-torque.

For owners doing their own servicing, keeping a small stash of genuine or OEM-quality washers makes life easy. Workshops will usually include a new washer as part of an oil and filter service, because it’s a known wear item. That tiny ring of aluminium keeps the Accord tidy underneath and the engine oil exactly where it should be.

Popular questions about 2014 Honda Accord sump-plug-washers

What size sump plug washer does a 2014 Honda Accord use?
It takes a 14 mm aluminium crush washer, commonly listed by Honda as part number 94109-14000 (or a superseding equivalent). Using the correct size and material ensures a proper seal without over-tightening.

How tight should the sump plug be on a 2014 Accord?
Honda service information specifies 39 N·m (29 lbf·ft). That torque compresses the new washer just enough to seal. Over-tightening risks stripping the sump threads, under-tightening can allow weeping.

Can the sump plug washer be reused?
It’s not recommended. The washer is designed to crush once. Reusing it often leads to minor leaks or the need to over-torque the bolt. Replace it at every oil change as part of normal servicing.
