Parts for your 2009 Suzuki Splash-Drive belt

2009 Suzuki Splash drive-belt — what it does and when to change it

Based on Suzuki service literature for the K10B/K12B petrol engines and the 1.3 DDiS diesel, plus major aftermarket catalogues (Gates Micro-V and Dayco application guides, and Autodata specifications), the 2009 Suzuki Splash does use an accessory/auxiliary drive-belt (serpentine belt). Those same technical sources confirm the Splash’s engines use a timing chain for the camshaft drive, not a rubber timing belt. So, while there’s no cambelt to schedule, the accessory drive-belt is very much relevant for servicing.

On a 2009 Splash, the drive-belt’s job is to spin key accessories off the crank pulley. On the common K10B/K12B petrols it drives the alternator and A/C compressor, and often the water pump, on diesel and some trims the exact accessory set can differ, but the principle’s the same. If that belt slips or fails, you can get battery warning lights, hot-running or no A/C, and the sort of squeal that turns heads in the car park for the wrong reasons.

For day‑to‑day care, it’s smart to have the belt checked at each service (about every 10,000–15,000 km or yearly in AU/NZ conditions). Look for cracks across the ribs, fraying, glazing (shiny ribs), missing chunks, or chirps/squeals on cold starts. A belt can also look fine but be stretched or hardened, so age matters too.

Replacement timing varies by use and climate, but as a friendly rule of thumb many tech sources recommend planning a belt and tensioner refresh around 90,000–120,000 km or six years, sooner if there’s noise, visible wear or accessory wobble. Always replace worn tensioners and idlers with the belt. A quality 6‑rib OE‑spec serpentine belt matched to the engine (K10B/K12B or DDiS) and A/C fitment is the go, routing diagrams are usually under the bonnet. Proper alignment and correct tension (if not automatic) are key to quiet, long‑lived running.

• Listen for squeals/chirps, especially on cold starts.
• Inspect ribs and edges each service, don’t ignore glazing or cracks.
• Renew belt, tensioner and idlers together for best results.
• Confirm the correct belt length by VIN/engine and A/C fitment.

Does a 2009 Suzuki Splash have a timing belt?

No. Technical references for the Splash’s K10B/K12B petrol and 1.3 DDiS engines specify a timing chain, not a cambelt. That means there’s no scheduled cambelt change, but the accessory drive‑belt still needs periodic inspection and replacement when worn.

How often should the drive-belt be replaced on a 2009 Splash?

Have it checked at every service and plan on replacement roughly every 90,000–120,000 km or about six years, earlier if there are squeals, cracks, glazing or charging/cooling issues. Local heat, dust and short trips in AU/NZ can shorten belt life.

What size belt does my Splash use?

It’s a 6‑rib serpentine style, but the exact length depends on engine (K10B vs K12B vs DDiS) and whether the car has A/C. The simplest way is to match by VIN/engine code through a parts catalogue or the belt label if still legible.
