Parts for your 1987 Suzuki Swift-Sump plug washers

1987 Suzuki Swift sump-plug-washers: what they do and when to replace them

Based on Suzuki factory documentation and parts catalogues, the 1987 Suzuki Swift does use a replaceable sump plug washer (drain plug gasket). The Suzuki Swift (SA/AA series, G10/G13 engines) Workshop Manual instructs fitting a new drain plug gasket at each oil change, and the Suzuki Electronic Parts Catalogue lists a “Gasket, drain plug” for the engine oil pan (commonly referenced as 09168‑14015 or similar, depending on engine/market). Independent guides such as the Haynes Suzuki Swift manual also specify replacing the washer during routine servicing.

Sump-plug-washers are small, inexpensive crush gaskets that sit between the oil drain plug and the sump. On a 1987 Suzuki Swift, their job is dead simple but critical: they deform slightly as the plug is tightened, sealing the mating surfaces so engine oil doesn’t seep past the threads. Without a good washer, even a correctly torqued plug can mist or drip, leaving spots on the driveway and slowly dropping oil level.

Because they’re designed to crush once, sump-plug-washers lose their elasticity after a service. Reusing a flattened washer can cause seepage, weeping around the plug, or the temptation to overtighten the plug to stop a leak. That’s risky on an older alloy sump. Fresh washers help maintain the right clamp load at the specified torque and keep the Swift tidy and leak-free.

For most 1987 Swifts, the drain plug is typically M14 x 1.25 and uses an aluminium or copper crush washer with an inner diameter around 14 mm, some variants may use M12. It’s best to confirm by checking the existing plug or referencing the VIN in a Suzuki parts catalogue. Practical tips when servicing:

• Always fit a new washer at each oil and filter change.
• Lightly oil the new washer face, start the plug by hand, then torque it to the workshop spec (commonly in the 30–35 N·m range, check the exact value in the Suzuki manual for the specific engine).
• If the sump face has old gasket residue, clean it with a lint-free rag before refitting.

A tidy approach for the 1987 Suzuki Swift is to keep a small pack of correct-size sump-plug-washers on the shelf. At each 10,000 km/12‑month service (or whatever interval you run), swap the washer, torque the plug, and check for any weeping after the first short drive. It’s cheap insurance for a dry, healthy little Swift.

What size sump-plug-washers does a 1987 Suzuki Swift use?

Most 1987 Swifts use an M14 drain plug with a 14 mm ID crush washer, some markets or engines may be M12. If unsure, measure the plug’s shank or reference the VIN in a Suzuki parts catalogue to grab the right washer.

How often should the sump-plug-washers be replaced on a 1987 Swift?

Replace at every oil change. These washers are designed to crush once, reusing them can cause weeping or leaks, or push you to overtighten the plug.

Can the old sump-plug-washers be reused if it looks OK?

It’s not recommended. Even if it looks fine, a used crush washer has already deformed and may not seal properly again. A new washer lets the plug seal at the correct torque without drama.
