Parts for your 2006 Nissan Primera-Sump plug washers

2006 Nissan Primera sump plug washers

For the 2006 Nissan Primera (P12 series), a sump plug washer is absolutely used and relevant. Technical sources back this up: the Nissan Primera P12 Workshop Manual (Engine Mechanical/Lubrication section) specifies replacing the drain plug washer at every engine oil change, and the Nissan FAST electronic parts catalogue lists a dedicated “Gasket – Drain Plug” for the oil pan on P12 models. Common Nissan part numbers catalogued for this washer include 11026-01M02 and its later supersession 11026-4N200, covering the P12’s typical engines (QG18DE 1.8 petrol, QR20DE 2.0 petrol, and YD22DDTi 2.2 diesel). These sources confirm the washer is a service item, not optional kit.

On the 2006 Nissan Primera, the sump plug washer (also called an oil drain plug gasket) does a simple but vital job: it crushes slightly as the drain plug is tightened, creating a proper seal between the plug and the sump. That prevents weeping and drips once fresh oil is back in. Nissan specifies a soft, crush-type aluminium washer for this model because it conforms reliably without needing excessive torque, protecting the alloy sump threads. It’s designed to be single-use, once crushed, it doesn’t spring back the same way next time.

Best practice for servicing is to fit a new washer at every oil change. It’s a low-cost part that helps avoid messy leaks and comebacks. During the service, the old washer should be removed and the mating surface on the sump and the drain plug head cleaned. The correct-size washer for the Primera is typically the 14 mm Nissan style listed in FAST (commonly 11026-01M02 or 11026-4N200). After refitting the plug with a new washer, tighten to the specification in the factory manual rather than “by feel” — overtightening can distort the washer or, worse, damage sump threads. Once the engine has run and warmed, a quick check underneath for any sign of oil around the plug is a smart move.

If there’s any evidence of oil mist, dampness, or a droplet forming on the plug after a change, plan to swap the washer and re-torque the plug. It’s also worth keeping a couple of genuine or quality aftermarket washers on hand for future services. For NZ and Aussie drivers who clock up plenty of kilometres, pairing regular oil changes with a fresh washer is an easy win for engine longevity and a tidy driveway.

• Replace the washer at every oil change.
• Use the correct Nissan-type crush washer (P12 catalogue fitments include 11026-01M02 / 11026-4N200).
• Tighten the drain plug to the factory spec and check for leaks after warm-up.

Popular questions

What size sump plug washer does a 2006 Nissan Primera use?
The Primera P12 typically uses a 14 mm crush-type aluminium washer as catalogued in Nissan FAST, with common genuine part numbers 11026-01M02 or 11026-4N200. Because some engines and production runs can vary, it’s wise to confirm by VIN or match the old washer’s dimensions before fitting.

How often should the sump plug washer be replaced?
Every oil change. The washer is designed to crush once and provide a fresh, reliable seal each service. Reusing an old washer increases the risk of weeping and the temptation to overtighten the plug, which isn’t worth the hassle.

What are the signs a sump plug washer needs replacing?
Look for fresh oil dampness around the drain plug, a slow drip after parking, or a faint oil mist on the sump’s underside. If the plug needed a lot of torque to stop a weep, that’s another hint the washer’s past it — fit a new one and torque correctly.
