Parts for your 2015 Honda Cr-v-Sump plug washers

2015 Honda CR‑V sump plug washers

Yes, the 2015 Honda CR‑V uses a sump plug washer (also called an oil drain plug gasket). Honda’s 2015 CR‑V Owner’s Manual and the corresponding Honda Service Manual specify replacing the drain plug washer at each engine oil change, and the Honda genuine parts catalogue lists an aluminium 14 mm crush washer for the drain plug. The service literature also specifies tightening the plug to about 39 N·m (29 lb‑ft), which assumes a fresh crush washer to seal correctly.

On this model, the sump plug washer’s job is simple but crucial: it crushes slightly as the plug is torqued, creating a tight seal between the plug head and the sump. That soft aluminium ring prevents weeping and drips, keeps oil where it belongs, and lets the plug reach the correct torque without chewing up the sump’s sealing face. It’s a small, inexpensive part that protects a very expensive alloy oil pan.

Best practice for a 2015 CR‑V is to fit a new washer at every oil change (typically every 10,000 km or 12 months in AU/NZ conditions, or as per the owner’s schedule). Reusing an already‑crushed washer can lead to slow leaks, under‑ or over‑torquing, and a mess on the driveway. A genuine Honda 14 mm aluminium crush washer or a high‑quality equivalent is recommended.

• Clean the sump’s sealing face and the plug head before refitting.
• Hand‑start the plug to avoid cross‑threading, then torque to about 39 N·m.
• Never double‑stack washers or add sealant, the crush washer does the sealing.
• After the first warm‑up, have a quick look underneath to confirm there’s no fresh oil misting around the plug.

Signs the old washer has had its day include a faint oil smell after a run, a damp spot on the bottom of the pan, or a single drop forming at the plug. If any of that shows up, fit a new washer and re‑torque correctly. Owners who service at home will find it handy to keep a small pack of washers on the shelf. It’s a cheap safeguard that keeps the CR‑V running clean and tidy between services.

Popular questions

What size sump plug washer does a 2015 Honda CR‑V use?
It takes a 14 mm aluminium crush washer that deforms once for a reliable seal. Sticking with a genuine‑spec washer helps ensure the correct crush and torque. If unsure, confirm by VIN with a Honda parts counter.

Do you really need to replace the washer at every oil change?
Yes—Honda’s service information calls for a new washer each time. Reusing an old, flattened washer is a common cause of slow leaks and can tempt over‑tightening, which risks damaging the sump threads.

What’s the correct torque for the sump plug on a 2015 CR‑V?
About 39 N·m (29 lb‑ft) with a fresh crush washer. Using a torque wrench and a new washer helps hit that sweet spot between too loose and over‑tight.
