Parts for your 2016 Suzuki Splash-Oil pump

2016 Suzuki Splash oil pump — what it does and when to sort it

Yes, the 2016 Suzuki Splash absolutely uses an engine oil pump. Factory sources list it as part of the standard pressurised lubrication system on all Splash engines. The Suzuki K10B/K12B petrol engine service manuals detail a crankshaft-driven trochoid oil pump in the lubrication section, the Suzuki electronic parts catalog shows the pump, pick-up and relief valve as serviceable components, and the 1.3 DDiS (MultiJet) diesel workshop manual likewise specifies an internal gear/trochoid pump. So an oil pump is both relevant and fitted to this vehicle.

On a 2016 Splash, the oil pump’s whole job is to push clean engine oil through galleries to bearings, timing gear and valvetrain so everything stays cool, quiet and protected. It’s mounted in the front cover and driven off the crank, with a built-in pressure relief valve to keep things steady across different revs. Without a healthy pump, oil pressure drops, the dash light flicks on, and metal bits start to complain in very expensive ways.

As part of regular servicing, the smartest move is to look after the oil system so the pump never has a hard day. That means sticking to proper oil and filter intervals, using the right grade for local temps (most NZ/AU petrol models are happy on a quality 5W-30 meeting the manufacturer’s spec, the DDiS diesel typically needs a low-SAPS oil meeting the correct ACEA rating). Sludge is the enemy of the pick-up strainer, keep oil fresh and it won’t gum up the works.

The oil pump itself isn’t a routine replacement item, but it’s worth a close look any time the front cover is off (timing chain work, major seal leaks) or if there’s a history of low oil pressure, bearing noise, or metal in the sump. If replacing, use a new pick-up O-ring/gasket, follow the sealant pattern in the service manual, and pre-lube/prime the pump so it doesn’t run dry on first start. After refit, verify pressure with a mechanical gauge and check for leaks under the bonnet once it’s heat-cycled.

• Common warning signs: low oil pressure light at idle, rattly cold starts, top-end ticking, rising engine temps, or glitter in the drained oil.
• Good habits: correct oil grade, quality filters, timely changes, and cleaning the sump and pick-up if there’s been sludge or a failure upstream.

If the Splash is a high-kilometre commuter or has seen irregular services, a preventative inspection of the pick-up strainer and front cover area during timing work can save a lot of grief later.

Popular questions about 2016 Suzuki Splash oil pumps

What type of oil pump does the 2016 Splash use?
The petrol K10B/K12B engines use a crank-driven trochoid (internal gear) pump integrated with the front cover and a relief valve. The 1.3 DDiS diesel uses a similar positive-displacement design. It’s built for steady pressure across the rev range.

When should the oil pump be replaced?
There’s no set interval. Replace if there’s confirmed low oil pressure, pump wear or scoring, a clogged or damaged pick-up, or during major front-cover/timing repairs where inspection shows excessive wear. Always diagnose pressure with a mechanical gauge first.

What oil should be used to keep the pump happy?
Use the manufacturer-specified viscosity and spec for your engine and climate—commonly a quality 5W-30 for petrol models in AU/NZ, and the correct low-SAPS spec oil for the DDiS diesel. Fresh, correct oil is the best protection for the pump and bearings.
