Parts for your 2017 Suzuki Splash-Drive belt pulley

2017 Suzuki Splash drive-belt pulley — what it does and when to replace it

Based on technical references including the Suzuki Service Manual for Splash/Swift K12B/K10B engines (Engine Mechanical and Maintenance sections), Suzuki’s Electronic Parts Catalogue (auxiliary drive group), and the Gates/Dayco application catalogues for Splash models, the 2017 Suzuki Splash uses an auxiliary drive belt and associated pulleys. These include the crankshaft (harmonic) pulley, alternator pulley, A/C compressor pulley and an automatic tensioner/idler. Most Splash variants use electric power steering, so there’s no belt-driven P/S pump in the mix.

The drive-belt pulley set on a 2017 Suzuki Splash keeps the essentials spinning under the bonnet. The crankshaft pulley drives the serpentine belt, which turns the alternator to keep the battery charged and runs the A/C compressor for cool air on a sticky arvo. The tensioner and idler pulleys keep the belt routed correctly and at the right tension, so nothing slips or squeals. On K12B/K10B engines, the cam timing is chain-driven, so the accessory belt isn’t a timing belt—different job entirely—but the accessory pulleys still cop daily wear.

As part of routine servicing, the belt and pulleys should be checked every 12 months or 15,000 km for Australia and New Zealand conditions. Look for cracking, frayed edges, glazing, or rubber dust on nearby covers. Spin the tensioner and idler by hand (engine off) and feel for roughness or play. Any chirps on cold start, squeals when you flick the A/C on, battery light flickers, or visible belt wobble are all signs the belt or a pulley is past its best.

Replacement is straightforward with the right gear. Use a serpentine belt tool to unload the tensioner, note the belt routing, and inspect each pulley face for wear tracks. If a pulley is noisy, rough, misaligned or wobbling, replace it—ideally with the belt and tensioner together, as recommended by common workshop practice and parts guides. Stick with OE-quality components, keep hands clear on first start, and never rely on spray-on “belt dressings” to quieten noise—they mask issues and can attack rubber. After fitting, recheck alignment and listen for any new noises. Done right, a new belt and healthy pulleys will run quietly for tens of thousands of kilometres.

• Service check interval: 12 months/15,000 km
• Typical belt life: 60,000–100,000 km, condition-dependent
• Replace pulleys if noisy, rough, or misaligned, replace tensioner with the belt for best results

FAQs

Does the 2017 Suzuki Splash actually have a drive-belt pulley?
Yes. Technical sources such as the Suzuki Service Manual, Suzuki EPC, and Gates/Dayco catalogues show a serpentine belt system with a crankshaft pulley, alternator pulley, A/C compressor pulley, and a tensioner/idler on Splash models.

How often should the belt and pulleys be replaced?
Inspect every 12 months or 15,000 km. Many belts last 60,000–100,000 km, but replace sooner if there’s cracking, noise, or pulley roughness. Replace a noisy or worn pulley immediately, and consider doing the belt and tensioner at the same time.

Is the Splash’s power steering on the belt?
Most 2017 Splash variants use electric power steering, so there’s no power-steering pump on the belt. The belt mainly drives the alternator and A/C compressor on these engines.
