Parts for your 2015 Suzuki Splash-Sump plug washers

2015 Suzuki Splash sump plug washers: what they do and when to replace them

Yes, the 2015 Suzuki Splash is fitted with a sump plug washer (also called the drain plug gasket), and it’s not just a nice-to-have. Suzuki’s factory service information for the K10B/K12B engines specifies “install drain plug with a new gasket” during an oil change, and the Suzuki Electronic Parts Catalogue lists a dedicated crush washer for the Splash’s oil drain plug (commonly referenced as gasket p/n 09168-14015 for M14 applications). Independent service references, including Haynes and Autodata, echo the same instruction: renew the sealing washer at each oil service. So, on this model, the sump plug washer is absolutely relevant and used.

On the Splash, that little washer is a soft aluminium or copper crush ring that lives under the drain plug head. When the plug is tightened, the washer deforms slightly to create a reliable seal against the sump. That crush action compensates for minor surface imperfections and thermal cycling, helping prevent weeping or outright drips after a few heat cycles. It’s a simple, cheap part that saves a lot of mess and hassle.

Good servicing practice on a 2015 Splash is to replace the sump plug washer at every engine oil change. These washers are designed as single-use items, once they’ve been crushed, they won’t spring back perfectly, and reusing them can lead to seepage. If there’s any sign of oil mist around the plug, a tell-tale spot on the driveway, or the old washer looks grooved, flattened, or hard, it’s time for a fresh one. Most Aussie and Kiwi workshops keep a handful on hand and fit a new washer as standard—no dramas, no leaks.

Handy tips for owners and techs looking after a 2015 Suzuki Splash:

• Use the correct-size washer for the Splash’s M14 drain plug, aluminium is common and works a treat.
• Clean the mating surface on the sump and the plug head before refitting.
• Tighten to the specification in Suzuki’s service data—firm, not gorilla tight—to avoid damaging threads or over-crushing the washer.
• After the first drive, have a quick look under the bonnet and underneath for any signs of weeping.

Bottom line: it’s a tiny part with a big job. Pop a new sump plug washer on at each service, and the Splash will stay tidy and leak-free between intervals.

Popular questions about 2015 Suzuki Splash sump plug washers

What size sump plug washer does a 2015 Suzuki Splash use?
Most 2015 Splash petrol variants use an M14 drain plug with a matching 14 mm ID crush washer, typically aluminium. Parts catalogues for the Splash list the Suzuki washer commonly referenced as 09168-14015. Always confirm against the vehicle’s VIN or the old washer before buying in bulk.

How often should the sump plug washer be replaced?
Best practice is to replace it at every oil change. The washer is a single-use crush seal, once compressed, it won’t seal as reliably if reused. Swapping it takes seconds and helps prevent annoying drips.

Can the old washer be reused in a pinch?
It can get you out of trouble once, but it’s not ideal. A reused washer is the most common cause of post-service seepage. If it must be reused, inspect for grooves or hard spots and check carefully for leaks afterwards—then replace with a new washer as soon as possible.
