Parts for your 2017 Suzuki Splash-Oil cap

2017 Suzuki Splash oil cap — what it does and how to look after it

Yes, the 2017 Suzuki Splash uses an oil cap. Technical literature identifies it as a standard component on the K10B and K12B petrol engines fitted to the Splash/Ritz platform. The Suzuki Splash Owner’s Manual (Engine Oil section) shows the oil filler cap on the cylinder head cover, while the K10B/K12B service manuals list the “Cap, Oil Filler” on the rocker/valve cover assembly. Suzuki’s parts catalogues also enumerate the component (commonly referenced under part family 11179—Cap, Oil Filler). So, the oil cap is absolutely relevant on a 2017 Splash.

On this model, the oil cap seals the top of the engine where oil is added under the bonnet. Its job is simple but critical: keep dust and moisture out, keep oil in, and maintain the crankcase’s intended ventilation behaviour. If the cap is loose, missing, or its seal has gone hard, oil can mist out over the cover, dirt can get in, and the engine may run a bit off because of the unintended airflow through the crankcase breather system.

Servicing-wise, the cap is an “on-condition” item, not a scheduled replacement. During each service or top-up, it’s worth giving the cap a quick once-over:

• Check the cap’s O-ring or gasket for hardening, cracks, or flattening.
• Make sure the cap threads and the filler neck are clean and free of grit.
• Refit the cap hand-tight until it seats positively—don’t overdo it.

If there’s an oil smell after a drive, fresh oil mist around the filler neck, or the cap feels sloppy, it’s time to replace it. Genuine Suzuki caps for K10B/K12B engines (often noted as 11179-63J00 or 11179-85K00, depending on build) are a safe bet, and quality aftermarket options work fine so long as the seal profile matches. In Aussie and Kiwi conditions—heat, dust, and plenty of stop–start—seals can age quicker, so a cap that’s five to ten years old is a fair candidate for renewal.

Replacing the cap is straightforward: let the engine cool, twist the old cap off anti-clockwise, wipe the neck with a clean rag, then install the new cap. After a top-up or cap swap, start the engine and check for any weeping. Never drive off with the cap removed—oil will fling out, contaminants can enter, and running quality can suffer.

Where is the oil cap on a 2017 Suzuki Splash?

It’s on top of the engine’s valve (rocker) cover under the bonnet, usually marked “OIL” (sometimes looks like “710”). On many Splash engines it’s black or yellow and sits near the centre or right-hand side of the cover.

What are the signs the oil cap needs replacing?

Look for a perished or flattened seal, difficulty tightening, oil mist around the filler area, or a hot-oil smell after driving. In some cases, idle quality may feel a touch rough if the cap isn’t sealing well.

Is it okay to drive without the oil cap?

No. Oil can spray inside the engine bay, dirt can get into the engine, and the crankcase ventilation balance is upset. Fit a correct cap before driving to avoid damage or a mess under the bonnet.
