Parts for your 2021 Suzuki Splash-Oil pump

2021 Suzuki Splash oil pump: is it fitted and what does it do?

Yes, an oil pump is fitted and absolutely relevant to the Suzuki Splash. Technical documentation for Splash powertrains confirms a mechanically driven engine oil pump across the range: the 1.0 K10B and 1.2 K12B petrol engines use a trochoid (internal gear) pump integrated at the front cover and driven by the crankshaft (Suzuki K10B/K12B Engine Workshop Manuals), while the 1.3 DDiS turbo‑diesel (Fiat Multijet) uses a gear‑type pump (FPT 1.3 Multijet Service Manual). The Suzuki Electronic Parts Catalogue for Splash/Ritz models also lists the complete oil pump assembly and related pickup/strainer and gaskets for these engines. Even though the Splash wasn’t widely sold as a 2021 model-year in many markets, vehicles registered or complied in 2021 still use these same engines and their factory oil pumps.

The oil pump’s whole job is to push pressurised oil through the engine so bearings, camshafts, timing components and the VVT system stay lubricated and cool. On a Splash, the pump picks up oil from the sump via a strainer, builds pressure, and routes it through galleries and filters. There’s a built‑in pressure relief valve so it doesn’t overdo it at higher revs. Without a healthy pump, you’ll see the low oil pressure light, top‑end clatter, VVT faults, or in the worst case, bearing damage.

As for servicing, the pump itself isn’t a routine replacement item
