Parts for your 2013 Honda Odyssey-Sump plug washers

2013 Honda Odyssey sump plug washers

Yes — the 2013 Honda Odyssey is designed to use a sump plug washer (crush washer) on the engine oil drain bolt. Honda’s own technical guidance in the 2013 Odyssey Owner’s Manual instructs replacing the drain bolt washer at each oil change, and Honda’s parts catalogue lists a 14 mm aluminium drain plug washer (commonly referenced as Honda part 94109-14000) for this model. The workshop torque spec for the drain bolt is 39 N·m (29 lbf·ft), which assumes a new crush washer is installed.

The sump plug washer’s whole job is to provide a reliable, one-time-use seal between the drain bolt and the sump. It deforms slightly as the bolt is torqued, filling tiny imperfections in the mating surfaces so engine oil can’t weep out. That controlled “crush” also helps the bolt reach its correct clamping force at the specified torque, reducing the risk of overtightening or damaging the alloy sump.

For the 2013 Odyssey, an aluminium 14 mm crush washer is the right style. Honda recommends fitting a new washer every service when the engine oil is changed. Reusing a flattened washer often leads to slow seepage, wetness around the plug, or the temptation to swing harder on the spanner — none of which is a great plan for the sump threads. If the washer looks grooved, distorted, or stuck to the pan, it’s time for a fresh one.

Owners and workshops in Australia and New Zealand will find these washers inexpensive and easy to keep on hand. They’re not directional, so there’s no special orientation to worry about. Stick with genuine or quality aftermarket aluminium washers rather than fibre or generic soft washers that don’t crush to spec.

• Clean the sump’s sealing face and the drain bolt before refitting.
• Always use a new 14 mm aluminium crush washer.
• Hand-start the bolt to avoid cross-threading, then torque to 39 N·m.
• Check for any film of oil after a short drive, a dry plug means the seal is doing its job.
• Dispose of the old washer and used oil responsibly.

These simple steps align with Honda’s service information and keep the Odyssey’s V6 running cleanly without those annoying drips on the driveway. It’s a tiny part that protects an expensive sump and keeps servicing tidy and drama-free.

Popular questions about 2013 Honda Odyssey sump plug washers

What size sump plug washer does a 2013 Honda Odyssey use?

The 2013 Odyssey uses a 14 mm aluminium crush washer on the engine oil drain bolt. It’s the standard Honda style used across many models and is often listed under Honda part number 94109-14000.

How often should the sump plug washer be replaced?

Replace it at every oil change or any time the drain bolt is removed. That matches Honda’s service guidance and helps ensure a clean, leak-free seal at the specified 39 N·m torque.

Can the washer be reused if it looks okay?

It’s not recommended. Once crushed, the washer won’t deform properly again, which can lead to seepage or overtightening risks. Given how inexpensive they are, a fresh washer each service is the smart move.
