Parts for your 2013 Honda Accord-Sump plug washers

2013 Honda Accord sump plug washers — what they do and when to replace them

Yes, the 2013 Honda Accord uses a sump plug (engine oil drain) washer. Honda’s service literature for the 9th‑gen Accord (K24W 2.4L and J35Y 3.5L) calls for a new drain plug washer at each oil change, and specifies tightening the plug to approximately 39 N·m (29 lbf·ft). Genuine Honda parts catalogues list an aluminium crush washer for the engine oil drain plug, commonly referenced as 14 mm (Honda P/N 94109‑14000). These sources collectively confirm the washer is fitted and intended to be replaced routinely.

The sump plug washer on a 2013 Honda Accord is a small, single‑use aluminium “crush” ring that sits between the drain plug head and the sump. Its job is dead simple but critical: once tightened, it deforms slightly to create a uniform seal, keeping fresh oil in and road grime out. Honda’s own guidance is to replace this washer every time the oil is changed, because once it’s crushed, it won’t spring back to seal properly again.

Skipping the washer or reusing a flat, hard one can lead to weeping around the plug, an annoying drip on the driveway, or needing extra torque to try to make an old seal work—none of which is great for the alloy sump threads. With a new washer installed and the plug torqued to about 39 N·m, the Accord’s sump stays dry and tidy between services.

Good practice for Accord owners and workshops in Aus/NZ:

• Keep a couple of genuine‑spec 14 mm crush washers on hand, they’re inexpensive and save hassles.
• Change the washer at every oil change—no exceptions, hot or cold service.
• Wipe the sump sealing face clean, any grit can compromise the new washer’s seal.
• Use a torque wrench. Over‑tightening won’t “help” the seal and can damage threads.
• If there’s any sign of a drip after servicing, recheck torque and confirm a new washer was fitted.

Tech heads will appreciate that the crush washer ensures consistent clamp load at the specified torque, which is why Honda pairs the washer with that 39 N·m spec. Whether it’s the 2.4L or 3.5L, the principle holds: fresh oil, fresh filter, fresh washer. It’s a tiny part that does a big job, and it’s one of the simplest wins for long‑term reliability of a 2013 Honda Accord.

Popular questions about 2013 Honda Accord sump plug washers

Does a 2013 Honda Accord need a sump plug washer every service?
Yes. Honda’s service procedures specify installing a new drain plug washer at each oil change. The aluminium crush design is single‑use, so replacing it helps guarantee a proper seal and prevents nuisance leaks.

What size is the sump plug washer on a 2013 Accord?
It uses a 14 mm aluminium crush washer, commonly referenced as Honda Genuine P/N 94109‑14000. This matches the M14 drain plug used on both 2.4L and 3.5L engines in the 2013 model range.

How tight should the sump plug be on a 2013 Accord?
Tighten the drain plug with a new washer to about 39 N·m (29 lbf·ft). Using the correct torque avoids over‑crushing the washer and protects the sump threads while delivering a leak‑free seal.
