Parts for your 2000 Honda Stream-Sump plug washers

2000 Honda Stream Sump Plug Washers

Per Honda’s own technical references—the Honda Stream (2000–2006) Service Manual under Engine Lubrication, and the Honda Electronic Parts Catalogue—the 2000 Honda Stream uses a sump (engine oil drain) plug with an aluminium crush washer. The commonly specified washer is 14 mm (Honda P/N 94109-14000), and the drain plug torque is 39 N·m (29 lbf·ft). So yes, a sump plug washer is absolutely fitted and relevant on this model.

The sump plug washer on a 2000 Honda Stream does a deceptively important job. It’s a soft, single-use aluminium ring that deforms slightly when the plug is tightened, creating a reliable seal between the sump and the drain plug. That crush effect prevents annoying weeps, oily drips on the driveway, and the slow oil loss that can creep up between services.

Because it’s designed to deform once, the washer should be replaced at every oil change. Reusing an old one might seem harmless, but once it’s compressed it can’t seal as well the second time, especially after a few heat cycles. Honda’s service guidance calls for a fresh washer each time along with tightening the plug to the correct spec—39 N·m. Over-tightening can distort the new washer or even damage the threads in the alloy sump, so a torque wrench is a smart move.

For Stream variants with the D17A 1.7-litre or K20A 2.0-litre engines, the washer spec is the same 14 mm aluminium crush type. It’s a cheap part that protects an expensive engine, and it’s one of those little details that separates a tidy service from a messy one.

• Replace the washer with every oil and filter change.
• Clean the sump sealing face and plug head before refitting.
• Hand-start the plug to avoid cross-threading, then torque to 39 N·m.
• After the engine’s run and cooled, check for any trace of seepage.

If the plug has been previously over-tightened, consider replacing the plug itself along with the washer. A fresh washer, correct torque, and clean sealing surfaces keep the 2000 Honda Stream leak-free and happy between services—too easy.

Popular questions about 2000 Honda Stream sump plug washers

What size sump plug washer does a 2000 Honda Stream use?
It uses a 14 mm aluminium crush washer, the standard Honda type used across many Stream and Civic-based engines. It’s a single-use sealing washer that’s designed to deform once for a perfect seal.

This suits both the 1.7-litre D-series and the 2.0-litre K-series engines found in the 2000 model range.

Do you really need to replace the washer at every oil change?
Yes—Honda’s service documentation treats the crush washer as a replace-every-time item. Reusing it risks minor leaks that can leave oil spots or, over time, drop the oil level.

They’re inexpensive, and swapping one in is a quick win for a clean, professional service.

How tight should the sump plug be on a 2000 Honda Stream?
Tighten to 39 N·m (29 lbf·ft). That’s enough to compress the new washer and seal the joint without stressing the threads or distorting the washer.

A light wipe to clean both faces, a fresh washer, and the correct torque is the sweet spot for a leak-free result.
