Parts for your 2011 Honda Cr-v-Sump plug washers

2011 Honda CR‑V sump plug washers

Yes, the 2011 Honda CR‑V uses a sump (engine oil drain) plug washer. Technical sources that specify this include: Honda’s 2010–2011 CR‑V Service Manual (Engine Lubrication), which calls for an aluminium drain plug gasket (14 mm) with a drain bolt torque of 39 N·m, the Honda Owner’s Manual instruction to “install a new washer on the drain bolt” during an oil change, and Honda’s Electronic Parts Catalogue listing a 14 mm aluminium crush washer (commonly referenced as p/n 94109‑14000) used with the 14 mm drain bolt (often referenced as p/n 90009‑PY3‑000) for the K‑series engine in the 2011 CR‑V.

On the 2011 Honda CR‑V, the sump plug washer is a simple but critical seal. It’s a soft aluminium crush washer that deforms slightly when the drain bolt is tightened, creating a snug seal between the bolt head and the oil pan. That seal helps prevent annoying drips on the driveway and protects against slow oil loss that could shorten engine life.

Best practice on this model is to replace the washer at every oil change. Honda’s workshop guidance expects a new washer each time the bolt comes out, because once it’s crushed, it won’t spring back to seal the same way again. Reusing a flattened or grooved washer is a common cause of weeps after a service.

Good servicing habits for the CR‑V’s sump plug washer include:

• Always fit a new 14 mm aluminium crush washer to the drain bolt before refitting.
• Clean the mating surfaces on the bolt and pan so the new washer can seal properly.
• Tighten the drain bolt with a torque wrench to 39 N·m (about 29 lbf·ft). Over‑tightening can distort the washer too much or damage the pan threads.
• After the oil change, run the engine, then check underneath for any signs of seepage once it’s cooled.

If there’s a drip after a change, the usual culprits are a reused washer, dirt on the sealing face, or the bolt not torqued correctly. A fresh genuine‑spec 14 mm washer is cheap insurance, so most DIYers keep a small stash on hand. For Aussie and Kiwi conditions and typical service intervals, swapping the washer at each oil change (every 10,000–15,000 kilometres or 12 months, depending on use and service schedule) keeps the CR‑V tidy and leak‑free.

Popular questions

What size sump plug washer does a 2011 Honda CR‑V use?
The 2011 CR‑V uses a 14 mm aluminium crush washer for the engine oil drain bolt. This single‑use washer is designed to compress and seal when torqued to about 39 N·m. Genuine Honda equivalents are widely available and inexpensive.

Can the sump plug washer be reused?
It’s not recommended. The CR‑V’s aluminium washer is designed to deform once. Reusing can lead to weeping around the drain bolt. Fit a new washer at each oil change for a no‑dramas seal.

What happens if the drain bolt is over‑tightened?
Over‑tightening can crush the washer unevenly, cause leaks, or worse, damage the oil pan threads. Use a torque wrench and stick to 39 N·m. If threads are already compromised, a proper thread insert repair may be needed.
