Parts for your 2001 Honda Accord-Sump plug washers

2001 Honda Accord sump plug washer — what it does and when to replace it

Yes, the 2001 Honda Accord uses a sump plug washer (also called a drain plug crush washer). This isn’t guesswork — Honda’s own publications specify it. The 2001 Accord Owner’s Manual instructs refitting the drain bolt with a new washer and tightening to 29 lbf·ft (39 N·m). The 1998–2002 Accord Service Manual (Helm Inc., Engine Lubrication section) carries the same guidance, and Honda’s parts catalog lists a 14 mm aluminium drain plug washer (commonly part no. 94109-14000) for both the 2.3L four-cylinder and the 3.0L V6. So, on this model, a sump plug washer is absolutely relevant and used.

On the 2001 Accord, the sump plug washer does the sealing work between the steel drain bolt and the aluminium sump. It’s a soft, single-use aluminium ring that crushes slightly as the plug is torqued, preventing weeps and protecting the sump threads from the temptation to overtighten. Without a fresh washer, the plug can bottom out before sealing, leading to slow leaks or a ham-fisted extra quarter-turn that risks pulling threads — an expensive fix.

As part of regular servicing, this is a cheap, simple win. Every oil change, fit a new washer, clean the mating face on the sump, and torque the plug correctly. That’s it. The washer is designed to deform once, reusing it is a false economy that can show up as a damp underside or spots on the driveway a week later.

• Washer type/size: 14 mm aluminium crush washer (Honda catalogue reference commonly 94109-14000).
• Tightening torque: 29 lbf·ft (39 N·m) — per Honda Owner’s and Service Manuals for the 2001 Accord.
• Replace interval: every oil change, always use a new washer.
• Watch-outs: don’t stack old washers, check for scoring on the sump seat, nip to spec, not “as tight as possible”.

Done properly, the little washer keeps the Accord tidy, leak-free, and makes the next service painless. It’s a small part that saves big headaches.

Popular questions about 2001 Honda Accord sump plug washers

What size washer does a 2001 Accord use?
It uses a 14 mm aluminium crush washer that matches the oil drain bolt. Honda’s catalogue commonly lists it as 94109-14000. Both the 2.3L four-cylinder and the 3.0L V6 for this model year typically use the same size.

How tight should the sump plug be on a 2001 Accord?
Honda specifies 29 lbf·ft (39 N·m). That’s tight enough to crush the washer and seal, without chewing out the aluminium sump threads. A small torque wrench is worth its weight in oil.

Can the washer be reused?
It’s a single-use crush washer. Reusing it can cause seepage or encourage overtightening to chase a seal. They’re inexpensive, so fit a new one at every oil change.
