Parts for your 2013 Honda Cr-v-Sump plug washers

2013 Honda CR‑V sump plug washers — what they do and when to replace them

Yes, the 2013 Honda CR‑V uses a sump plug washer (also called a drain plug gasket). Honda’s own documents specify it: the 2013 Honda CR‑V Owner’s Manual requires a new washer whenever the engine oil is changed, and the Honda CR‑V Service Manual (2012–2014, Publication No. 61T7A00) shows the drain plug with a replaceable crush washer. Honda’s genuine parts catalogue lists the correct washer as “Washer, Drain Plug, 14 mm” (commonly P/N 94109‑14000) and gives a tightening torque of 39 N·m (29 lbf·ft) with a new washer fitted.

On a 2013 CR‑V, that little alloy crush washer is doing big work. It sits between the sump (oil pan) and the drain plug, and when the plug is torqued, the washer deforms to create a tight seal. That crush action stops slow weeps and drips, keeps the driveway clean, and helps maintain proper oil level between services. Because it’s designed to deform once, Honda wants it replaced at every oil change—cheap insurance for a tidy, leak‑free engine.

During servicing, the advice is simple: every time the oil is drained, fit a new 14 mm Honda washer, then tighten the plug to 39 N·m. Reusing a flattened or gouged washer can lead to seepage, overtightening, or even stripped threads as people chase a seal with extra grunt. A fresh washer means the correct torque achieves the proper seal, first go.

It’s an easy add‑on to your service kit. Most owners and techs keep a small stash of genuine or OEM‑equivalent washers on hand. If the old washer has bonded to the sump, peel it off carefully so the mating face stays clean and flat—no sealant or tape needed. After refilling with the correct oil, have a quick look under the bonnet and underneath after the first drive, any oily mist around the plug is a sign the washer wasn’t replaced or the plug isn’t torqued correctly.

• Washer type: aluminium crush washer, 14 mm ID (Honda P/N commonly 94109‑14000).
• When to replace: every oil change (as per Owner’s Manual and Service Manual).
• Torque: 39 N·m (29 lbf·ft) on the drain plug with a new washer.
• Tell‑tales of trouble: oil drip from the plug, damp sump area, or plug that feels loose after a drive.

Whether the CR‑V is petrol or diesel in your market, Honda’s guidance is the same: use a new crush washer each time and torque it properly. It’s a tiny part that saves a lot of hassle.

Popular questions about 2013 Honda CR‑V sump plug washers

Do I really need to replace the sump plug washer at every oil change?
Honda says yes, and it’s there for a reason. The washer is designed to crush once to form a perfect seal. Reusing it risks slow leaks or the temptation to overtighten the plug. Given how inexpensive it is, replacing it each time is the smart move.

What size and part number washer does a 2013 CR‑V use?
It’s a 14 mm aluminium crush washer used on the engine oil drain plug. Honda commonly lists it as P/N 94109‑14000. Plenty of quality aftermarket equivalents are available, but sticking with the correct size and style matters for a reliable seal.

What’s the correct torque for the drain plug with a new washer?
Tighten the drain plug to 39 N·m (29 lbf·ft). That torque, paired with a fresh crush washer, delivers the seal Honda intended without stressing the threads.
