2019 Honda Accord sump plug washers — what they do and when to replace them
Yes, a sump plug washer is used on the 2019 Honda Accord. Honda’s service information for the 2018–2020 Accord range, along with the Honda Genuine Parts catalogue, specifies an aluminium crush washer on the engine oil drain (sump) plug. The commonly listed Honda part is a 14 mm aluminium drain plug washer (often referenced as P/N 94109-14000), used across the 1.5T, 2.0T and many hybrid variants. These sources call for replacement of the washer at each oil change, and a drain plug torque of about 39 N·m.
On this Accord, the sump plug washer is a small, single-use seal that sits between the sump and the drain bolt. When tightened, the soft aluminium deforms to fill tiny imperfections, creating a proper seal that keeps engine oil where it should be. Reusing a flattened washer can lead to weeping around the plug, messy drips on the driveway, and under-torquing or over-torquing to chase a seal.
For easy, drama-free servicing of a 2019 Honda Accord, replacing the washer is a no-brainer. It’s inexpensive, takes seconds to fit, and helps protect the sump threads by allowing the correct torque to do its job. Most dealers and quality service kits include a fresh washer as standard practice.
- When to replace: Every oil change (as per Honda’s Maintenance Minder or roughly every 10,000 km/12 months common in AU/NZ conditions).
- Why replace: The washer work-hardens after one use and won’t crush properly again, risking leaks.
- Size/material: 14 mm aluminium crush type for the Accord’s M14 x 1.5 drain bolt.
- Remove the old washer and clean the sump’s sealing face.
- Fit a new aluminium washer onto the drain bolt.
- Install and torque the plug to about 39 N·m (use a torque wrench for accuracy).
- Top up oil, run the engine, and check for any weeping at the plug after warm-up.
Signs it needs attention include a faint oil ring around the drain bolt, a visibly gouged or wafer-flat washer, or oil spots under the car after a service. Keeping a couple of genuine or quality aftermarket washers in the glovebox is a smart move for DIYers and travellers alike.
Popular questions about 2019 Honda Accord sump plug washers
Do all 2019 Accord engines use the same sump plug washer?
The petrol 1.5T and 2.0T engines typically use the same 14 mm aluminium crush washer, and many hybrids do as well. It’s best to confirm with the VIN or engine code, but in practice, most AU/NZ 2019 Accords share this washer spec.
How often should the washer be replaced?
Replace it at every oil change. It’s a single‑use crush washer and is designed to deform once for a perfect seal. Skipping replacement can lead to slow leaks and messy underbody oiling.
What torque should the drain plug be tightened to?
Honda service information commonly specifies about 39 N·m for the Accord’s drain plug. Use a torque wrench rather than guessing, it helps avoid stripped threads and ensures the new washer seals properly.
