Parts for your 2002 Honda Fit-Sump plug washers

2002 Honda Fit sump plug washers

Yes, the 2002 Honda Fit (also sold as the Jazz in Australia and New Zealand) uses a sump plug washer. Honda’s GD-series service manual for the L13A engine, the Honda Genuine Parts Catalogue, and owner’s maintenance guidance all specify a replaceable aluminium crush washer on the engine oil drain bolt. The commonly listed Honda part is a 14 mm aluminium washer (often referenced as Honda P/N 94109-14000). That means sump plug washers are absolutely relevant to this model’s regular servicing.

The sump plug washer’s job is simple but crucial: it’s a soft, single-use seal that deforms slightly when the drain bolt is tightened, creating a reliable, leak-free seal between the sump and the bolt. Reusing a crushed washer can lead to weeping around the plug, drip spots on the driveway, or the temptation to overtighten the bolt—risking damaged threads in the alloy sump, which nobody wants.

Honda service information advises fitting a new washer at each oil change. For typical AU/NZ servicing, that means every 10,000 km or 12 months, whichever comes first, unless your schedule differs. When refitting the drain bolt with a fresh washer, torque it to Honda’s service spec of about 29 N·m (21 lb·ft) on the GD Fit/Jazz. Using a torque wrench helps avoid both undertightening (potential seepage) and overtightening (thread damage).

• What to watch for: oily mist around the plug, fresh drips after a service, or a washer that looks gouged, hardened, or flattened unevenly.
• Best practice: keep a few spare 14 mm aluminium crush washers in the glovebox or toolbox—cheap insurance for hassle-free oil changes.
• Parts choice: genuine Honda or quality aftermarket aluminium washers are fine, just match the size (for the M14 drain bolt). Copper can work, but aluminium is what Honda specifies for the right crush characteristics.

Quick change tip under the bonnet: warm the engine, drain the oil, wipe the mating surfaces clean, slip on a new washer, and torque the bolt correctly. After refilling, run the engine, shut it off, and check under the car for any sign of seepage. Simple, tidy, and spot on for long engine life.

Popular questions

What size sump plug washer does a 2002 Honda Fit/Jazz use?
It uses a 14 mm aluminium crush washer for the M14 drain bolt. This size is the standard Honda fitment across many models of the era and is called out in Honda parts catalogues for the GD-series Fit/Jazz.

How often should the sump plug washer be replaced on a 2002 Honda Fit?
Replace it at every oil change. Honda’s service literature specifies using a new drain bolt washer each time to maintain a proper seal and prevent leaks or overtightening.

Can a copper washer be used instead of the Honda aluminium one?
While a quality copper washer can seal, Honda specifies aluminium for the correct crush and torque feel. If copper is used, ensure the size is correct and check carefully for leaks after installation.
