Parts for your 2007 Toyota Camry-Sump plug washers

2007 Toyota Camry sump plug washers — what they do and when to replace them

Based on Toyota factory information, the 2007 Toyota Camry does use a sump plug washer (also called an engine oil drain plug gasket). The Toyota Service Information (TIS) Repair Manual for the 2007 Camry (covering both 2AZ-FE 2.4L and 2GR-FE 3.5L engines) specifies refitting the drain plug with a new gasket during an oil change. Toyota’s genuine parts catalogue lists the drain plug gasket as a service item for this model, commonly referenced as an aluminium crush washer (e.g., Toyota p/n 90430-12031) that fits the 12 mm drain bolt. These technical sources confirm the washer is fitted and intended to be renewed at service time.

For a 2007 Camry, the sump plug washer is a small, single-use sealing ring that sits between the oil sump and the drain plug head. When tightened, it “crushes” slightly to form a reliable seal, stopping pesky drips that can leave spots on the driveway and slowly drop the engine oil level. It’s a simple bit of kit, but it does an important job.

As part of routine servicing, it’s good practice to replace the washer every oil change. Toyota’s workshop guidance is to install a new gasket whenever the plug is removed. Reusing an old washer can lead to weeps, especially if it’s been flattened or scored. If someone’s in a bind and must reuse it once, it should be inspected closely for nicks, deep grooves, or distortion—and then swapped at the next opportunity.

Most 2007 Camry variants take an aluminium 12 mm crush washer. Genuine Toyota options are ideal, but quality aftermarket equivalents that match the size and profile also do the trick. When fitting:

• Clean the mating surface on the sump and the drain plug head.
• Position the new washer flat against the sump, then install the plug.
• Tighten to the torque specified in the Toyota manual—don’t overdo it.
• After refilling the oil, check for leaks with the engine running, then again after a short drive.

A fresh washer helps prevent slow leaks, keeps oil levels stable between services, and avoids contamination on undertrays. It’s inexpensive insurance for the 2AZ-FE and 2GR-FE engines, and a tidy way to keep the Camry running sweet as without drips or drama.

Popular questions

What size sump plug washer does a 2007 Camry use?
The 2007 Camry typically uses a 12 mm aluminium crush washer on the engine oil drain plug. The genuine Toyota gasket is commonly listed under part number 90430-12031. Always check by VIN or engine code (2AZ-FE or 2GR-FE) if unsure.

How often should the washer be replaced?
Best practice is to replace the sump plug washer at every oil change. It’s designed to deform once for a proper seal. Reusing it can increase the chance of weeping or drips.

Can the old washer be reused if it looks fine?
It can be tempting, but it’s not recommended. Even if it looks alright, the crush layer may have already done its job. If it must be reused in a pinch, inspect for grooves or distortion and monitor for leaks—then replace at the next service.
