Parts for your 2020 Suzuki Splash-Oil pump

2020 Suzuki Splash oil pump — purpose, servicing and replacement advice

Short answer: yes, the Suzuki Splash uses an oil pump. Technical references including the Suzuki Splash/Ritz Service Manual (Lubrication System section), the K12B/K10B Engine Workshop Manual, and Suzuki’s electronic parts catalogue all specify a crankshaft-driven trochoid (gerotor) oil pump mounted in the front cover for the 1.0 K10B and 1.2 K12B petrol engines, and a pressure pump for the 1.3 DDiS diesel. Even though the Splash finished production earlier in many markets, any Splash registered or on the road in 2020 still relies on that pump to circulate engine oil under pressure.

On the 2020-era Suzuki Splash, the oil pump’s job is to pick up oil from the sump and push it through the filter and galleries to bearings, camshafts and timing components. It keeps a stable oil film between moving parts, manages heat, and carries away contaminants to the filter. Without proper pump output, the engine can cop rapid wear or seizure — so it’s a small part doing a massive job.

For servicing, the oil pump itself isn’t a routine replacement item, but it lives or dies by oil quality. Sticking to the correct viscosity and spec oil, changing it and the filter on time, and keeping the pickup screen clean are the biggest wins. If the low oil pressure warning appears, or there’s top-end rattle at hot idle, don’t keep driving — check oil level first, then have pressure tested with a mechanical gauge. A worn pump, blocked pickup, tired relief valve, or excessive bearing clearances can all drop pressure.

Replacement is usually done with the sump and front cover off. It’s worth inspecting the pickup O-ring, relief valve function, and chain/cover condition at the same time. Use new seals, follow the workshop manual torque procedures, and prime the pump with fresh oil before start-up to avoid a dry first crank. After refitting, verify pressure and watch for leaks. Many owners pair a pump change with timing chain cover work, or when fixing a rear main or sump gasket, to save on duplicate labour.

• Watch-fors: low-pressure light at idle when hot, noisy lifters or cam, metallic glitter in oil, and delayed pressure after cold starts.
• Good habits: quality oil and filters, regular intervals, and not ignoring warning lamps — especially on long summer runs across Aus or NZ.

Popular questions about 2020 Suzuki Splash oil pumps

How long does a Splash oil pump usually last?
With proper servicing, the factory pump typically lasts the life of the engine. High kilometres, sludge from skipped oil changes, or debris from internal wear can shorten its run. If oil pressure stays solid and the engine’s healthy, there’s no set “change-by” kilometre count.

What are the symptoms of a failing oil pump on a Splash?
A flickering or steady low oil pressure light (especially at hot idle), ticking from the top end, and obvious bearing rumble under load are red flags. Always confirm with a mechanical pressure test before condemning the pump — a blocked pickup, wrong oil grade, or worn bearings can mimic pump failure.

Is the Splash oil pump the same as the Swift’s K12B pump?
Many K12B components are shared across Suzuki models, but part numbers can differ by year and market. Always check against the VIN in a parts catalogue to ensure the correct pump, pickup, and gasket set for your particular Splash.
