Parts for your 2010 Toyota Camry-Sump plug washers

2010 Toyota Camry sump plug washers

Technical sources confirm the 2010 Toyota Camry uses a sump plug washer. Toyota’s Repair Manual for the 2AR‑FE and 2GR‑FE engines specifies fitting a new oil pan drain plug gasket at each oil change and torquing the plug correctly. The Toyota Owner’s Manual for this model reinforces installing a new gasket on the drain plug during servicing. Toyota’s Electronic Parts Catalogue lists the oil drain plug gasket (washer) as part number 90430‑12031 (aluminium crush type) for 2010 Camry variants. With that, a sump plug washer is absolutely relevant and fitted on this vehicle.

On the 2010 Toyota Camry, the sump plug washer is a small but critical hero. It’s a single‑use aluminium crush washer that sits between the sump (oil pan) and the drain plug. When tightened, it compresses to seal tiny imperfections in the mating surfaces, stopping annoying weeps and drips that can leave spots on the driveway or a faint oil mist under the car. Both the 2.5‑litre 2AR‑FE and the 3.5‑litre 2GR‑FE engines use this washer, so it’s standard kit across the range.

It’s designed to be replaced every oil change. Once crushed, it won’t spring back properly on the next service, so reusing it can lead to slow leaks. A genuine Toyota 90430‑12031 washer or a quality 12 mm aluminium equivalent is the go. When refitting the drain plug, clean the sump face, slip on a fresh washer, nip it up by hand and then torque it to spec. For this model, the typical oil drain plug torque is around 39 N·m (29 ft‑lb). Over‑tightening is a classic way to distort the washer or, worse, damage threads—so a torque wrench is worth its weight.

A few handy tips owners and techs in Australia and New Zealand stick by:

• Always use a new crush washer at each service to keep things bone dry.
• Inspect after the first short drive—no sheen, no drip, all good.
• If an aftermarket magnetic plug has been fitted, confirm it still uses the same 12 mm crush washer type.
• Don’t mix it up with the oil filter housing O‑rings on cartridge‑filter models—those are separate seals altogether.

Signs a washer needs attention include a damp ring around the plug, a visible groove in the old washer, or an oil spot under the front of the car after a service. Keeping a couple of spares in the glovebox makes life easy—cheap insurance for a tidy, leak‑free Camry.
