Parts for your 2012 Toyota Camry-Sump plug washers

2012 Toyota Camry sump plug washers — what they do and when to replace them

A 2012 Toyota Camry does use a sump plug washer. Toyota’s own technical literature specifies a drain plug “gasket” that’s replaced at oil changes, and the Toyota Genuine Parts catalogue lists a “Gasket, Oil Drain Plug” commonly supplied as part number 90430‑12031 for 2012 Camry variants (2AR‑FE 2.5L and 2GR‑FE 3.5L). The Toyota repair manual procedure for engine oil replacement describes removing the drain plug and gasket, then refitting a new gasket before torquing the plug to spec. Those factory sources make it clear the washer is a designed sealing component, not an optional extra.

On this Camry, the sump plug washer is a crush-style sealing ring that sits between the drain plug head and the sump. When the plug is tightened, the soft metal washer deforms slightly to create a proper seal. That prevents annoying drips on the driveway, keeps oil where it should be, and helps protect the alloy pan face from scoring caused by metal-on-metal contact.

• Provides a reliable oil-tight seal
• Reduces the chance of leaks after servicing
• Protects the sump face from damage when tightening

Best practice on a 2012 Camry is to replace the sump plug washer at every oil change. They’re inexpensive and designed to crush once, reusing a flattened washer can lead to weeping, over-tightening to “chase” a seal, or even a stripped thread. If a previous owner or shop has reused the washer, look for tell-tales like a polished, deeply flattened ring, nicks, or seepage around the plug.

1. Remove the plug and discard the old washer.
2. Wipe the sump face clean, make sure no old gasket material is stuck on.
3. Fit a new washer to the plug, thread it in by hand, and tighten to the factory torque listed in the repair manual.
4. Run the engine, then check for leaks after a few minutes and again after a short drive.

Most 2012 Camry models use a 12 mm inside-diameter crush washer with the M12 drain plug. The genuine Toyota washer (often 90430‑12031) is a safe bet, quality aftermarket equivalents are fine too. If unsure, match by VIN or engine code, as North American, Australian, and NZ-delivered vehicles can vary by market.

Keeping a couple of spare washers in the glovebox or service kit makes every oil change straightforward and drama-free. Replace it, tighten to spec, and the Camry will stay clean, dry, and happy between services.

How often should the sump plug washer be replaced on a 2012 Camry?

Replace it at every oil and filter service. The washer is designed to deform once, reusing it can cause seepage or tempt over-tightening, which is bad news for the sump threads.
