Parts for your 2012 Honda Cr-v-Sump plug washers

2012 Honda CR‑V sump‑plug‑washers: what they do and when to change them

For the 2012 Honda CR‑V, sump‑plug‑washers are definitely used and relevant. Honda specifies a single‑use aluminium crush washer on the engine oil drain (sump) plug. Technical references include the 2012 Honda CR‑V Owner’s Manual (Engine Oil and Filter section), which instructs replacing the drain bolt washer at each oil change, and the Honda Factory Service Manual (Engine Lubrication) that calls up a new 14 mm sealing washer and the correct torque on re‑fit. Genuine Honda part numbers commonly used are the 14 mm drain plug washer (often listed as 94109‑14000 or 90471‑PX4‑000).

On this model, the sump‑plug‑washer is a soft aluminium ring designed to crush slightly as the drain bolt is tightened. That controlled crush creates a reliable seal between the bolt head and the sump, preventing weeps and drips as the engine warms, cools, and vibrates. It’s a simple, inexpensive part that does a big job—keeping the oil where it should be.

• When to replace: every oil change. Honda’s documentation treats the washer as single‑use. Reusing it can lead to seepage or the temptation to over‑tighten the bolt.
• Torque spec: tighten the drain bolt to about 39 N·m (29 lb‑ft). Over‑tightening can distort the washer or damage threads, under‑tightening can cause leaks.
• What to buy: a 14 mm ID aluminium crush washer. Genuine Honda is ideal, quality aftermarket equivalents also do the trick.

As part of routine servicing on a 2012 Honda CR‑V, it’s smart to keep a couple of spare sump‑plug‑washers on hand. At oil change time, remove the old washer from the bolt (they can stick), fit a fresh washer, thread the bolt in by hand to avoid cross‑threading, and tighten to spec. After the first heat cycle, a quick glance under the vehicle for any misting around the plug is good practice. If there’s a weep, the common culprits are a reused washer, incorrect torque, or a washer that’s the wrong size.

Owners in Australia and New Zealand often service on time or distance—whichever comes first—so pairing each oil change with a new sump‑plug‑washer is an easy, low‑cost way to prevent oil spots on the driveway and protect the CR‑V’s K‑series engine for the long haul.

Popular questions about 2012 Honda CR‑V sump‑plug‑washers

What size sump‑plug‑washer does a 2012 Honda CR‑V use?
It uses a 14 mm aluminium crush washer for the engine oil drain bolt. Genuine Honda listings commonly reference 94109‑14000 or 90471‑PX4‑000. Quality aftermarket 14 mm crush washers are fine if they match the correct dimensions and material.

How often should the sump‑plug‑washer be replaced?
Replace it at every oil change. Honda’s guidance treats the washer as single‑use because it deforms to seal properly only once. Swapping it each service helps avoid drips and saves the hassle of redoing work.

What’s the correct torque for the drain bolt with a new washer?
Tighten the engine oil drain bolt to about 39 N·m (29 lb‑ft). Using a torque wrench is best practice—over‑tightening can crush the washer too far or damage threads, while under‑tightening risks leaks.
