Parts for your 2015 Honda Accord-Sump plug washers

2015 Honda Accord sump plug washers

Yes, a sump plug washer is absolutely used on the 2015 Honda Accord. Honda’s own technical literature specifies an aluminium crush washer on the engine oil drain (sump) plug, and that it must be replaced at each oil change. References: 2015 Honda Accord Owner’s Manual (Maintenance – Engine Oil) and Honda Accord 2013–2017 Service Manual (Engine Lubrication), both of which state to “always replace the drain bolt washer” and torque the drain bolt correctly. Honda’s parts catalogue also lists the 14 mm aluminium drain washer (commonly part number 94109-14000) for this model.

On this Accord, the sump plug washer’s job is simple but critical: it deforms as the plug is tightened to create a reliable seal between the plug and the sump. That soft aluminium “crush” prevents weeping and full-on leaks, which protects the engine from low oil level and your driveway from stains. Because it’s designed to deform, it’s a single-use item—once crushed, it won’t spring back or seal the same way again.

Best practice for servicing a 2015 Honda Accord is to replace the washer at every oil change—whether you follow the Maintenance Minder or a typical local interval of about 10,000 km or 12 months. Fit the correct-size washer (14 mm ID aluminium), clean the mating surfaces, start the plug by hand to avoid cross-threading, and tighten to the specified torque of 39 N·m (29 lbf·ft). No sealant, tape, or doubling-up of washers is required or recommended.

If the old washer is reused, the plug often needs extra grunt to “chase” a seal, which risks damaging threads in the alloy sump. Reuse is also the usual culprit behind slow oil drips that appear days after a service. A fresh, correct washer is cheap insurance against both problems.

Technical sources for this guidance: Honda Accord 2013–2017 Service Manual (Engine Lubrication – Engine Oil Replacement procedure and torque spec), 2015 Honda Accord Owner’s Manual (Engine Oil and Filter – replace drain bolt washer note), and Honda Genuine Parts listings for the aluminium 14 mm drain washer (94109-14000). These collectively confirm the washer is fitted, single-use, and part of normal service.

Popular questions

What size and type of sump plug washer does a 2015 Honda Accord use?
The Accord uses a 14 mm aluminium crush washer on the sump plug, typically Honda part 94109-14000. It’s designed to deform once to seal properly, so it’s considered single-use. This applies to both the 2.4-litre and 3.5-litre engines.

How often should the sump plug washer be replaced on a 2015 Honda Accord?
Replace it at every oil change. Whether you follow Honda’s Maintenance Minder or service it about every 10,000 km or 12 months locally, fit a new washer each time the plug is removed to avoid drips and over-tightening.

Can a copper washer be used instead of aluminium on the Accord?
Copper can seal if it’s the correct 14 mm size and properly annealed, but Honda specifies an aluminium crush washer. For a guaranteed fit and the correct crush characteristics, stick with the Honda-style aluminium washer.
