Parts for your 2018 Suzuki Splash-Timing belt kit

2018 Suzuki Splash timing belt kit — is it even a thing?

Short answer: a timing-belt kit isn’t used on the 2018 Suzuki Splash. The Splash engines in this model line are chain-driven, so there’s no cam belt and no belt kit to replace. That applies to the common petrol K10B 1.0 and K12B 1.2 engines, and the 1.3 DDiS diesel (Fiat Multijet) where fitted.

This isn’t just hearsay. Multiple technical sources specify a timing chain for these engines and show no timing belt service interval. These include Suzuki workshop manuals for K10B/K12B (timing chain drive layout), the Splash owner’s handbook/maintenance schedule (no timing belt replacement item), and major catalogue data from Autodata, Gates, Dayco and INA for AU/NZ applications that note “chain” or “no timing belt fitted” for Splash engines.

Why no timing-belt kit on a 2018 Suzuki Splash? Suzuki designed these engines with a duplex chain to drive the cams. A timing chain runs inside the engine, lubricated by engine oil, and is intended to last the life of the engine under normal conditions. That means there’s no scheduled belt change, no tensioner/idler kit like you’d see on a belt-driven setup, and no water pump tie-in to a timing-belt job.

What owners should keep in mind instead is chain health via good maintenance. Use the correct oil spec and change it on time (or earlier if doing lots of short trips). Old, dirty, or low oil accelerates chain and tensioner wear and can cause rattle at start-up. If any chain noise appears, or if there are cam/crank correlation fault codes, get it checked promptly — that’s a timing chain and tensioner assessment, not a belt kit replacement.

Seeing “belt kits” listed online for a Splash? Those are typically auxiliary/serpentine drive components, not the cam drive. They’re worthwhile to replace when cracked or noisy, but they are unrelated to the engine’s timing system.

Bottom line for servicing in Australia and New Zealand: there’s no timing-belt kit for a 2018-registered Splash because it doesn’t use one. Focus on quality oil, proper intervals, and listening out for unusual timing chain noise — that’s the smart way to keep the Splash happy.

Popular questions

Does a 2018 Suzuki Splash have a timing belt or a timing chain?
It has a timing chain. The K10B/K12B petrol and 1.3 DDiS diesel engines in the Splash use a chain-driven cam setup, so there’s no timing-belt kit or scheduled belt replacement.

When should the timing “belt” be changed on a 2018 Splash?
There’s no timing belt to change. Instead, maintain the timing chain by sticking to the correct oil spec and service intervals. If chain rattle or related fault codes show up, have a technician inspect the chain, guides and tensioner.

I found a “belt kit” for my Splash online — is that the timing belt?
No — those are usually auxiliary/serpentine belt kits. They drive the alternator, A/C and power steering, not the camshafts. They should be replaced if worn, but they aren’t a timing-belt kit.
