Parts for your 2009 Suzuki Splash-Drive belt pulley

2009 Suzuki Splash Drive-Belt Pulley — Purpose, Care, and Replacement

Technical sources including the Suzuki Splash Service Manual (2008–2014), Suzuki Electronic Parts Catalogue (EPC), and major aftermarket catalogues (Gates and Dayco), plus Autodata, confirm that the 2009 Suzuki Splash uses an auxiliary/serpentine drive belt with associated pulleys. This means a drive-belt pulley is absolutely relevant to this model, across both the 1.0 K10B and 1.2 K12B petrol engines.

On this Splash, the crankshaft drive-belt pulley (often a rubber-damped harmonic balancer) transfers engine rotation to the auxiliary belt to run key accessories such as the alternator and, where fitted, the air-conditioning compressor. Some variants also employ idler and tensioner pulleys to guide and tension the belt, the alternator may have a solid or overrunning (decoupler) pulley depending on build. While the water pump drive differs by engine variant, the presence of the auxiliary belt system and its pulleys is consistent across the line-up.

Routine servicing should include a visual and audible check under the bonnet. A healthy pulley runs true, stays quiet, and keeps the belt tracking centred. Tell-tales of trouble include belt squeal at cold start, charging issues or dim lights at idle, a wobbly crank pulley, visible rubber delamination on the harmonic balancer, or black belt dust around the covers. A chirp that changes with electrical load can point to an alternator pulley or tensioner bearing starting to go.

Inspection intervals of every 12 months or 15,000 km suit most Aussie and Kiwi conditions. Many workshops replace the belt between 60,000 and 100,000 km, and it’s smart to evaluate the tensioner and idler pulleys at the same time. Oil leaks should be fixed promptly—oil contamination shortens belt and pulley life. When replacing parts, match by VIN and engine code (K10B or K12B) to ensure the correct pulley design and offset.

DIY-savvy owners can handle basic checks, but replacement demands proper tools. Use the correct square-drive on the automatic tensioner to unload the belt, follow the belt-routing decal under the bonnet, and never lever against a pulley lip. Spin each pulley by hand for roughness, confirm alignment with a straight-edge, and after start-up watch for runout. Quality OEM-equivalent components and fresh fasteners are worth the spend, and a quick re-check after a few hundred kilometres helps catch any early settling.

• Replace the pulley if there’s wobble, cracking or delamination on the damper.
• Replace if bearings feel rough, noisy, or show heat discolouration.
• Replace if the belt can’t hold tension or keeps walking off a rib.

Popular questions about the 2009 Suzuki Splash drive-belt pulley

Which engines in the 2009 Splash use a drive-belt pulley?
The 1.0-litre K10B and 1.2-litre K12B engines both use an auxiliary belt system with a crankshaft pulley driving the alternator and, where fitted, the A/C compressor. Water pump drive varies by engine, but the accessory pulley system is present across the range.

How can a failing crankshaft (harmonic balancer) pulley be spotted?
Look for a visible split or creep in the rubber damper, a pulley face that wobbles with the engine running, persistent belt noise, or vibration at certain revs. Belt dust around the lower cover and intermittent charging can also be clues. Any of these signs warrants immediate inspection and likely replacement.

Does the Splash alternator use a one‑way clutch pulley?
Some builds may run an overrunning alternator decoupler (OAD), while others have a solid pulley. The sure way to confirm is by checking the alternator part number against the Suzuki EPC or a trusted parts catalogue. If fitted, an OAD that’s seized or freewheeling both ways can cause belt flutter and noise.
