Parts for your 2017 Honda Accord-Sump plug washers

2017 Honda Accord sump plug washers

Yes, the 2017 Honda Accord uses a crush-type sump plug washer. Technical references from Honda back this up: the 2017 Accord Owner’s Manual (Engine Oil & Filter), the 2013–2017 Accord Service Manual—Lubrication chapter, and the Honda Genuine Parts catalogue all specify replacing the drain plug washer at every oil change. The commonly listed Honda washer is “Washer, Drain Plug (14 mm)”, P/N 94109-14000, and the drain bolt tightening specification is 39 N·m (29 lb‑ft). This applies across the 2.4‑litre four, the 3.5‑litre V6, and the Hybrid.

On this Accord, the sump plug washer is a small, single‑use aluminium ring that crushes slightly as the drain bolt is torqued. That controlled crush creates a reliable, oil‑tight seal between the steel bolt and the alloy sump, helping prevent weeping and the gradual loosening that can come from thermal cycling. It also protects the sump face by sealing at the washer, rather than relying on metal‑to‑metal contact.

Because it’s designed to deform once, Honda has owners and techs fit a new washer at each service. Reusing a flattened washer can lead to slow leaks, drips on the driveway, and the temptation to over‑tighten the bolt—never ideal on an alloy pan. A fresh, genuine‑spec washer is inexpensive insurance and keeps servicing tidy and drama‑free.

When changing oil on a 2017 Accord, clean the sump face, fit a new 14 mm aluminium crush washer to the drain bolt, and torque the bolt to 39 N·m (29 lb‑ft). Don’t stack old washers, don’t use sealant, and don’t crank past spec—if it seeps, the fix is a new washer, not more grunt. While you’re there, inspect the bolt head and threads, replace the bolt if it’s rounded or burred. For high‑kilometre cars or vehicles that see frequent short trips, sticking to the replace‑every‑service rule is the simplest way to keep the lubrication system tight and happy.

Popular questions

What size sump plug washer does a 2017 Honda Accord use?
The 2017 Accord uses a 14 mm aluminium crush washer on the engine oil drain bolt. Honda lists it as “Washer, Drain Plug (14 mm)” with part number 94109‑14000. This size and style is specified in Honda’s parts catalogue and service information for the 2.4‑litre, 3.5‑litre V6, and Hybrid variants.

Can the sump plug washer be reused?
It’s designed as single‑use. Honda’s service guidance calls for a new washer at each oil change because the aluminium ring permanently crushes to seal. Reusing it risks weeping or leaks and can encourage over‑tightening, which is bad news for an alloy sump.

What’s the correct torque for the drain bolt on a 2017 Accord?
Honda specifies 39 N·m (29 lb‑ft) for the engine oil drain bolt. With a clean mating face and a fresh washer, that torque provides the proper crush and an oil‑tight seal without stressing the threads.
