Parts for your 2020 Honda Cr-v-Sump plug washers

2020 Honda CR‑V sump plug washers

For the 2020 Honda CR‑V, a sump plug washer is absolutely used and relevant. Honda’s workshop manual for the RW series CR‑V (covering the 1.5‑litre turbo petrol) specifies a replaceable aluminium crush washer on the engine oil drain (sump) plug, and the owner’s manual service notes call for fitting a new washer at each oil change. Honda’s genuine parts catalogue lists a 14 mm drain plug washer (commonly referenced as “Washer, Drain Plug 14 mm,” p/n 94109‑14000) for this model. Typical Honda torque guidance for the CR‑V’s drain plug is 39 N·m (about 29 lb‑ft), which assumes a fresh crush washer in place.

On this model, the sump plug washer is the small, single‑use aluminium ring that sits under the drain plug head. When tightened, it compresses slightly to create a snug seal between the plug and the sump, keeping engine oil where it belongs and helping avoid annoying drips on the driveway. Because it deforms to seal, it’s designed to be replaced every time the plug is removed. Reusing an old one can lead to weeping oil, plug over‑tightening to chase a seal, or even damage to the sump threads.

During routine servicing of a 2020 Honda CR‑V, swapping the washer is a cheap bit of preventative maintenance that saves hassles later. It also lets the technician torque the plug correctly without leaning on the spanner. For local service schedules (often around every 10,000 km or 12 months in Australia and New Zealand, depending on conditions), fitting a fresh washer each time is the go.

• Use a quality 14 mm Honda‑spec aluminium crush washer.
• Clean the sump’s mating face and the plug before refitting.
• Install the new washer on the plug, then torque the plug to 39 N·m.
• After refill, run the engine, shut down, and check for any weeping at the plug.

Signs a washer’s overdue include a faint oil halo around the plug, evidence of seepage after an oil change, or a washer that’s noticeably flattened, gouged, or hard. Keeping a small pack of genuine or high‑quality aftermarket washers on hand makes at‑home servicing smooth and keeps the CR‑V tidy underneath.

FAQs

What size sump plug washer does the 2020 Honda CR‑V use?

It takes a 14 mm aluminium crush washer for the engine oil drain plug (commonly referenced by Honda as p/n 94109‑14000). The drain plug itself typically has a 17 mm hex head, but the sealing diameter is 14 mm. Stick with the correct 14 mm crush type to ensure a proper seal.

How often should the sump plug washer be replaced?

Every time the sump plug is removed—so, at each engine oil change. For most owners that’s about every 10,000 km or 12 months locally, but follow the service schedule that suits your driving. Replacing the washer each time helps achieve the correct torque and prevents seepage.

What’s the correct torque for the 2020 CR‑V sump plug?

Torque the engine oil drain plug to 39 N·m when installing with a new crush washer. If tightened without a fresh washer, you may need more force to stop a leak, which risks damaging threads. Always use a new washer and a torque wrench for a clean, reliable seal.
