Parts for your 2007 Nissan Maxima-Sump plug washers

2007 Nissan Maxima sump-plug-washers

Yes — the 2007 Nissan Maxima uses a sump plug washer (also called an oil drain plug gasket). Nissan’s Factory Service Manual for the Maxima (Engine Lubrication section) specifies replacing the drain plug gasket whenever the engine oil is drained and refilled, and the parts catalogue lists a 14 mm crush-type washer for this model. Common OEM references include Nissan 11026-01M02 (often superseded by 11026-JA00A in some markets), used across VQ35DE-equipped Maxima variants (A34 and J31 platforms). Torque spec is provided in the service manual for the specific engine/market and typically sits around the mid-30s N·m range, always confirm against the manual.

On a 2007 Maxima, the sump plug washer is a small but critical seal that sits between the drain plug head and the sump. Its job is to deform slightly (that’s why it’s called a crush washer) to create a tight, leak-free seal when the plug is torqued up. Without a good washer, the oil can weep out slowly or, worse, the plug can be over-tightened to compensate — which risks stripping threads or damaging the sump. Most genuine and quality aftermarket options are aluminium or copper, sized to suit the Maxima’s 14 mm drain plug.

As part of regular servicing, it’s good practice to replace the washer at every oil change. They’re designed as single-use items: once they’ve crushed, they don’t spring back the same way next time. If someone’s reused an old washer, tell-tale signs include a film of oil around the plug, drips on the driveway, or a washer that looks flattened, ridged, or gouged. Swapping it is cheap insurance against leaks.

Handy tips for a tidy job:

• Always fit a new 14 mm crush washer to a clean, undamaged plug and sump face.
• Torque the plug to the factory spec for your Maxima variant — no need to “gorilla” it.
• Don’t stack washers, don’t use PTFE tape, and avoid sealants unless the manual explicitly says so.
• If the plug head is burred or the threads look suspect, replace the plug as well.

For Aussie and Kiwi owners doing driveway services, keeping a couple of genuine-spec washers on hand means every oil change goes back together leak-free, first time, with no dramas.

Popular questions about 2007 Nissan Maxima sump-plug-washers

What size sump plug washer does a 2007 Maxima take?
The 2007 Maxima typically uses a 14 mm crush washer for the oil drain plug. Genuine Nissan listings commonly reference 11026-01M02 (often superseded by 11026-JA00A). Always match by engine/market and measure the old washer if in doubt, as aftermarket pans or plugs can vary.

How often should the washer be replaced?
Replace the sump plug washer at every oil change. It’s a single-use crush gasket that deforms to seal, reusing it risks slow leaks and over-tightening. Given the low cost, it’s a no-brainer to fit a fresh one with each service.

Can the old washer be reused in a pinch?
It can physically be refitted, but it’s not recommended. A reused washer may not seal reliably, which can leave a weep or leak. If you’re stuck, monitor for seepage and replace with a new correct-size washer ASAP to keep the Maxima tidy and protected.
