Parts for your 2009 Honda Cr-v-Sump plug washers

2009 Honda CR‑V sump‑plug washers — what they do and when to replace

Yes, the 2009 Honda CR‑V is fitted with a sump‑plug washer (also called an oil drain plug crush washer). Technical sources confirm this: the Honda CR‑V 2007–2011 Service Manual (Engine Lubrication section) specifies a 14 mm aluminium crush washer for the engine oil drain plug, to be replaced at each oil change, with a tightening torque of 39 N·m (29 lbf·ft). The Honda Genuine Parts Catalogue for the 2009 CR‑V lists the “Washer, Drain Plug (14 mm)” (commonly referenced as Honda P/N 94109‑14000). The 2009 CR‑V Owner’s Manual also instructs refitting the drain bolt with a new washer during an oil change.

On this CR‑V, the sump‑plug washer is a soft, single‑use ring that deforms slightly as the drain bolt is tightened. That controlled “crush” seals the plug against the sump, so engine oil stays put without needing excessive torque. It’s a simple, inexpensive part that saves the sump threads from damage and prevents weeping or drips.

For routine servicing, it’s best practice to fit a new washer every oil change. Reusing an old one can seem harmless, but once it’s crushed it won’t seal the same again, which can lead to slow leaks, oil stains on the driveway, or an over‑tightened plug while chasing a seal. None of that is fun.

Handy tips for the 2009 CR‑V:

• Use the correct 14 mm aluminium crush washer (Honda spec, widely available). Keep a few spares in the glovebox or tool kit.
• Clean the sump face and the plug’s seating surface before refitting. Any grit can compromise the seal.
• Tighten the drain plug to 39 N·m (29 lbf·ft). Don’t lean on it harder — the washer does the sealing, not brute force.
• After the oil change, run the engine, then check around the plug for any sign of seepage. If it weeps, the washer may be wrong‑size, reused, or the mating face needs another clean.

If the plug has been over‑tightened in the past, the washer may mask minor issues for a while, but it won’t fix damaged threads. In that case, address the thread condition before the next service. With the right washer and torque, the CR‑V’s sump stays dry, the job’s tidy, and the next service is no dramas.

Does the 2009 Honda CR‑V use a sump plug washer?
Absolutely. Honda specifies a 14 mm aluminium crush washer for the drain plug on this model. It’s designed to be replaced at every oil change to maintain a proper seal and avoid leaks.

Can the sump‑plug washer be reused on a 2009 CR‑V?
It’s not recommended. The washer is single‑use — once crushed, it won’t seal the same again. Reusing can lead to oil weeps or the temptation to overtighten the plug, which risks damaging the sump threads.

What torque should the drain plug be tightened to?
For the 2009 CR‑V, tighten the drain plug to 39 N·m (29 lbf·ft). That, with a fresh 14 mm crush washer, gives a reliable seal without stressing the sump.
