Parts for your 2014 Nissan Pulsar-Sump plug washers

2014 Nissan Pulsar sump plug washers

Based on Nissan’s factory documentation and parts catalogues, the 2014 Nissan Pulsar (B17 sedan and C12 hatch, including MR18DE and MR16DDT SSS) uses a crush-type sump plug washer on the engine oil drain plug. The Nissan Electronic Service Manual for these models specifies a drain plug gasket and lists a torque in the typical 34–39 N·m range for a sealed plug. Nissan Genuine Parts catalogues list the drain plug gasket as Gasket–Drain, commonly part number 11026-4N200 (superseding earlier 11026-01M02 in many applications), with equivalent listings such as 11026-JD00A appearing in aftermarket catalogues for the same engines. That confirms a sump plug washer is fitted and relevant for this vehicle.

The sump plug washer on a 2014 Nissan Pulsar is a small, soft-metal crush ring that sits between the oil pan and the drain plug head. Its job is simple but crucial: once the plug is torqued up, the washer deforms to create a tight seal so engine oil doesn’t weep out. On the Pulsar’s alloy sump and steel plug combo, this crush action also spreads load so the pan face doesn’t get chewed up. Whether it’s the MR18DE commuter or the punchier MR16DDT SSS, the washer does the same heavy lifting—keeping oil in and dust out.

As part of regular servicing, it’s smart practice to replace the washer at every oil change. They’re designed as single-use items, once they’ve been crushed, they won’t spring back and can’t reliably reseal. Reusing a flattened washer often leads to a slow seep that shows up as a damp halo around the plug, a telltale drip on the driveway, or the need to overtighten the plug—none of which is ideal. Fit a new 14 mm Nissan-spec crush washer (e.g., 11026-4N200 or equivalent), clean the mating faces, and torque the plug to spec (typically 34–39 N·m for these models). Avoid “gorilla tight”—overtightening can distort the pan face or damage threads.

Handy tips owners appreciate:

• Always inspect the old washer to make sure it isn’t stuck to the pan.
• If the plug’s flange is scored, replace the plug along with the washer.
• After the first short drive, have a quick look underneath—no fresh oil mist means the seal’s doing its job.

What size sump plug washer does a 2014 Nissan Pulsar use?

It takes a 14 mm ID crush washer. Nissan genuine options commonly include 11026-4N200 (superseding earlier listings) or equivalent aftermarket aluminium/copper crush washers sized for Nissan drain plugs. They’re single-use by design.

How often should the sump plug washer be replaced?

Replace at every oil change. A fresh crush washer ensures the plug seals at the correct torque without over-tightening, reducing the risk of leaks and protecting the sump face.

What are signs the washer needs attention?

Look for a light oil weep around the drain plug, a small drip after parking, or the feeling that the plug needs extra grunt to seal. Any of these suggests the old washer has been flattened and should be swapped for a new one.
