Parts for your 2019 Suzuki Splash-Oil pump

2019 Suzuki Splash oil pump — what it does and how to look after it

Short answer: yes, the 2019-registered Suzuki Splash uses an engine oil pump. Technical references including the Suzuki Splash/Ritz workshop manual for the K12B and K10B petrol engines (and the D13A/1.3 DDiS diesel), OEM parts catalogues, and Autodata specifications all show a crank-driven trochoid (internal gear) oil pump mounted at the front of the engine. So, the oil pump is absolutely relevant on any 2019 Splash still on the road, even if the model itself was built earlier and first registered later.

The oil pump’s job is straightforward but vital: it pulls oil from the sump through a pickup and strainer, then pushes it under pressure through the galleries to the crankshaft and rod bearings, camshafts, timing chain, and variable valve timing gear. This oil not only lubricates, it also helps cool and clean moving parts. A pressure relief valve in the pump regulates flow so the system isn’t over-pressurised.

In normal servicing, the oil pump isn’t a scheduled replacement item. Instead, good oil and filter habits are the best protection. For Aussie and Kiwi conditions, quality engine oil meeting the spec in the owner’s book (commonly 5W-30 API SN/ILSAC for petrol variants) and timely changes are key—especially if the car sees short trips or hot summers. Using a decent filter with an anti-drainback valve helps the pump build pressure quickly on cold starts.

When should the pump get attention? Look for the oil pressure warning light, top-end ticking or timing chain rattle on start-up, bearing knock, low pressure readings on a mechanical gauge, or metal debris in the sump. If the sump is off for other work (say, sealing or big-end inspection), it’s smart to clean the pickup strainer, replace the pickup O-ring, and check the relief valve for sticking.

• Replacement pointers (pro level): remove the sump cleanly, avoid excess sealant, inspect the pump rotor/case for scoring, renew gaskets/O-rings, and prime the pump with clean oil before refitting.
• After refitting: verify hot oil pressure with a gauge, then recheck for leaks after a short drive.
• Diesel DDiS owners: healthy oil pressure is extra important for turbo life—stick to shorter oil intervals.

Treat the Splash’s oil pump well with the right oil, tidy sealing, and a clean pickup, and it’ll quietly get on with the job for a very long time.

Popular questions

Does a 2019 Suzuki Splash actually have an oil pump?
Yes. The Splash/Ritz engines (K12B, K10B, and the 1.3 DDiS) all use a crank-driven trochoid oil pump. This is documented in Suzuki workshop literature and recognised by Autodata and OEM parts catalogues. Even if the badge year is 2019, the underlying engine design is the same and includes the oil pump.

When should the oil pump be replaced on a Splash?
There’s no set interval. It’s replaced when diagnostics point to a fault—persistent low oil pressure, noisy starts, a sticking relief valve, or visible rotor/case wear during sump-off inspection. Always confirm with a mechanical pressure test before calling it.

What oil should be used to keep the pump happy?
Use the grade and spec in the owner’s manual—commonly a quality 5W-30 meeting API SN/ILSAC for petrol engines in AU/NZ climates. Stick to regular change intervals, and use a reputable filter. For DDiS diesels, follow the low-ash specs recommended for the emission system and consider shorter intervals if the car does lots of stop–start driving.
