Parts for your 2002 Honda Stream-Sump plug washers

2002 Honda Stream sump plug washers — what they do and when to replace them

Yes, the 2002 Honda Stream uses a sump plug washer. Honda’s own technical references confirm it: the factory Service Manual for the Stream (RN1/RN3) specifies a replace-after-removal aluminium crush washer for the engine oil drain bolt, the 2002 Owner’s Manual notes fitting a new washer at oil changes, and the Honda Electronic Parts Catalogue lists a 14 mm “Washer, Drain Plug” (commonly referenced as 94109-14000) for the model. The manual’s torque guidance typically states to tighten the drain bolt to about 39 N·m (29 lbf·ft) with a new washer installed.

On the 2002 Honda Stream, the sump plug washer is a small but crucial sealing ring that sits between the oil drain bolt and the sump. It’s designed to deform slightly (crush) when torqued, creating a reliable seal that keeps engine oil where it should be. Because it’s a crush type, it’s considered single‑use: once compressed, it won’t spring back to seal the same way again. That’s why Honda prescribes replacing it at each oil change, right alongside the filter and fresh oil.

Leaving an old washer in place can lead to a few headaches: minor weeping that dots the driveway, a slow oil loss over kilometres, or the temptation to overtighten the bolt to stop a drip—risking damage to the sump threads. A fresh washer lets the bolt reach its specified torque cleanly, sealing without brute force. For the Stream’s typical M14 x 1.5 drain bolt, an OEM‑spec aluminium washer (14 mm ID) is the go.

Practical tips when servicing a 2002 Honda Stream:

• Always match the washer size (14 mm ID) and choose quality aluminium crush types.
• Wipe the sump face and bolt head clean, grit compromises the seal.
• Hand‑start the bolt to avoid cross‑threading, then torque to about 39 N·m (29 lbf·ft).
• If there’s any doubt—nicks on the sump face, scored bolt head—replace the affected part.

Drivers who keep a small stash of genuine or high‑quality aftermarket washers make oil changes easier. It’s a low‑cost part that protects the Stream’s sump threads, keeps oil tight, and helps the 1.7 or 2.0 i‑VTEC run sweet between services.

Does the 2002 Honda Stream definitely have a sump plug washer?

It does. Honda documentation for the Stream (RN1/RN3) specifies a replaceable aluminium crush washer fitted to the engine oil drain bolt, and the parts listings show a 14 mm drain plug washer for this model.

What size sump plug washer suits a 2002 Honda Stream?

It takes a 14 mm inside diameter aluminium crush washer for the M14 x 1.5 drain bolt. The common Honda OEM reference is a 14 mm “Washer, Drain Plug” used across many Honda engines of that era.

How often should the sump plug washer be replaced on a 2002 Honda Stream?

Replace it at every oil change. It’s a single‑use crush washer, so fitting a fresh one each service ensures a proper seal and the correct torque without over‑tightening.
