Parts for your 2017 Nissan Pulsar-Sump plug washers

2017 Nissan Pulsar sump plug washers

Based on Nissan technical literature, the 2013–2017 Pulsar range (B17 sedan and C12 hatch, covering MR/MR16/MR18-series petrol engines) uses a replace-on-removal, crush-type sump plug washer on the engine oil drain plug. The Nissan Electronic Service Manual (ESM) sections for Maintenance and Engine Mechanical specify fitting a new drain plug gasket at each oil change to ensure a reliable seal. So yes—this model is fitted with a sump plug washer and it’s a normal service item.

The 2017 Nissan Pulsar uses a crush-type sump plug washer to seal the engine oil drain plug against the sump. This small ring sits between the plug head and the pan surface, compressing as the plug is tightened to create a leak-tight, serviceable seal. Relying on the threads alone isn’t enough to hold warm, thinned-out oil after repeated heat cycles, so the washer does the critical sealing work.

Most Pulsars of this era run an aluminium (sometimes copper) washer. It’s designed to be single-use: the metal cold-flows when tightened, conforming to tiny imperfections in the mating faces. Once it has been crushed, it won’t spring back or reseal the same way twice. That’s why Nissan workshop procedures call for replacing the washer any time the drain plug is removed during an oil change.

For servicing, fitting a fresh washer each oil change is cheap insurance. Owners should look for weeping around the plug after a service, oil spots under the car, or the smell of hot oil after a drive—classic signs the old washer was reused or the wrong type was installed. Over-tightening the plug to “make it seal” isn’t the fix and risks stripping threads, the correct torque and a new washer are what keep it tidy and dry.

Choosing the right washer matters. Use a crush washer that matches the Pulsar’s drain plug size and seat style, stick with a quality OEM-equivalent, and avoid sealants on the threads—they’re unnecessary and can contaminate the oil system. A quick wipe of the sump face, a new washer, and a properly torqued plug will see most Aussie and Kiwi Pulsars stay leak-free between services, whether commuting in city traffic or running long country kilometres.

• Popular questions related to 2017 Nissan Pulsar sump plug washers

What size sump plug washer does a 2017 Nissan Pulsar use?
Most 2017 Pulsar variants use a 14 mm internal-diameter crush washer, but there are engine and market variations. The safest bet is to match the new washer to the removed one or confirm by VIN with a parts catalogue before servicing.

How often should the sump plug washer be replaced?
Nissan workshop procedures specify replacing the washer every time the drain plug is removed—typically at each engine oil change. It’s inexpensive and prevents seepage, thread damage from over-tightening, and messy driveways.

Can the sump plug washer be reused if it looks okay?
It’s not recommended. Crush washers deform permanently to seal once. Reusing them risks small leaks that can worsen with heat cycles. Fit a fresh washer and tighten the plug to the specified torque for a proper, long-lasting seal.
