Parts for your 2019 Toyota Camry-Sump plug washers

2019 Toyota Camry sump plug washers — what they are and when to replace them

For the 2019 Toyota Camry (XV70), a sump plug washer is absolutely used and relevant. Technical sources confirm it: the Toyota Genuine Parts Catalogue (EPC) lists a replaceable aluminium drain plug gasket for this model (commonly 12 mm, Toyota part number 90430‑12031) across both the A25A‑FKS 2.5‑litre and 2GR‑FKS 3.5‑litre engines. Toyota’s Repair Manual on TIS (Engine/Hybrid System → Engine Oil → Replacement) also specifies installing a “new gasket to the drain plug” and tightening the plug to the specified torque during each oil change. That makes the sump plug washer a standard service item on a 2019 Camry.

This little crush washer does a big job. It sits between the sump (oil pan) and the drain bolt, deforming slightly as the bolt is tightened to create a reliable, oil‑tight seal. It helps prevent seeps and drips, and it protects the pan face and threads by allowing proper clamping force at the correct torque. Because it’s designed to crush once, it’s considered single‑use, reusing it can lead to weeping oil, loosening over time, or inconsistent torque feel.

As part of regular servicing in Australia and New Zealand, it’s smart to replace the sump plug washer at every oil change (typically every 10,000 kilometres or 12 months, or per the severe‑duty schedule if applicable). A new washer costs very little and saves headaches later. When installing, clean the mating surfaces, fit the correct‑size aluminium washer, and torque the drain plug to the spec in Toyota’s service data. Avoid over‑tightening, that can distort the washer too much or, worse, damage threads in the alloy sump.

Owners will appreciate a few practical tips the workshop follows:

• Keep a couple of genuine‑spec washers on hand (12 mm ID for the Camry XV70 engines).
• Never stack washers or mix materials that don’t crush uniformly.
• After a service, have a quick look under the car over the next day or two for any fresh oil misting around the plug.
• If a washer must be reused in a pinch, it should be inspected meticulously for grooves or flattening—but plan to replace it at the next opportunity.

If there’s a faint oil smell after parking, a small spot on the driveway, or oily residue tracking from the drain bolt, a tired or reused washer is often the culprit. Replacing it with the correct Toyota‑spec gasket restores a crisp seal and keeps the 2019 Camry tidy and leak‑free.

Popular questions about 2019 Toyota Camry sump plug washers

What size and part number sump plug washer does the 2019 Camry use?

For the XV70 2019 Camry, Toyota specifies an aluminium crush washer commonly referenced as 12 mm (approx. 12 x 22 mm). A widely used genuine Toyota part number is 90430‑12031. That size suits both the 2.5‑litre A25A‑FKS and 3.5‑litre 2GR‑FKS engines. Quality aftermarket equivalents listing the same dimensions are fine if they match the OEM spec.

How often should the sump plug washer be replaced?

Replace it at every oil change. In AU/NZ conditions that’s typically every 10,000 kilometres or 12 months, unless your servicing schedule calls for shorter intervals. The washer is a single‑use crush design—fitting a new one each service ensures a reliable seal and consistent torque on the drain plug.

Can reusing the washer cause leaks or damage?

Yes, reusing a crushed washer can lead to weeping oil, loosening over time, or needing extra torque to stop a seep—risking damaged threads in the sump. A fresh, correct‑spec aluminium washer seals properly at the specified torque and helps protect the sump and drain bolt from overtightening.
