Parts for your 2020 Toyota Camry-Sump plug washers

2020 Toyota Camry sump plug washers

Based on Toyota’s own technical literature and parts listings, the 2020 Toyota Camry does use a sump plug washer (also called an oil drain plug gasket). The Toyota Repair Manual for the 2018–2022 Camry specifies installing the engine oil drain plug with a new gasket at each oil change, and the Toyota Electronic Parts Catalog lists an aluminium crush-type washer (commonly Toyota part number 90430-12031) for the oil pan drain plug on both the 2.5‑litre A25A-FKS and 3.5‑litre 2GR-FKS engines. These sources confirm the sump-plug-washers are a relevant, serviceable item on this vehicle.

For the 2020 Camry, the sump-plug-washers do a simple but critical job: they deform slightly as the plug is tightened, creating a reliable seal between the sump and the plug so engine oil doesn’t seep past the threads. Being a crush washer, it’s designed as a single-use part. Reusing it can lead to small leaks, weeping, or the temptation to over-tighten the plug to compensate, which risks damaging the sump threads.

Servicing advice for this model is straightforward. Replace the washer at every oil change, whether the service interval is based on kilometres or time. When fitting the new washer, clean the mating surfaces so the soft aluminium can bed in evenly. Tighten the drain plug to the specified torque (typically about 39–40 N·m for Toyota four- and six-cylinder petrol engines of this era) rather than “by feel.” That keeps the crush washer working as intended without crushing it flat or stressing the threads.

Good practice on a 2020 Camry service includes the following:

• Always have a new 14 mm aluminium crush washer on hand (Toyota 90430‑12031 or the current supersession for your VIN).
• Inspect the old washer after removal, if it’s deeply grooved or flattened, that’s normal—don’t reuse it.
• Wipe the sump face and plug head clean before refitting to avoid grit compromising the seal.
• After refill, run the engine, then check around the plug for any weeping. Re-torque if necessary, but don’t over-tighten.

Following Toyota’s workshop guidance—new washer each time, correct torque, and clean surfaces—keeps the Camry’s underside dry, the garage floor spotless, and the engine oil right where it should be.

Popular questions about 2020 Toyota Camry sump-plug-washers

What size and part number washer does a 2020 Camry use?
Most 2020 Camry petrol models use a 14 mm aluminium crush washer, commonly Toyota part number 90430‑12031. Toyota may supersede part numbers over time, so it’s smart to confirm against your VIN or engine code (A25A‑FKS or 2GR‑FKS) when ordering.

How often should the sump plug washer be replaced?
Every oil change. The washer is designed to deform once to create the seal. Reusing it can lead to minor leaks or require extra torque on the plug, which isn’t ideal for the alloy sump threads.

What torque should the sump plug be tightened to?
Around 39–40 N·m is typical for the 2020 Camry’s engines per Toyota workshop guidance. Using a torque wrench is best practice to protect the threads and ensure the aluminium washer seals correctly.
