Parts for your 2020 Suzuki Splash-Drive belt pulley

2020 Suzuki Splash drive-belt pulley — what it does and when to service it

Yes, a drive-belt pulley is used on the Suzuki Splash. Factory service information and parts catalogues for the Splash/Ritz with the K10B 1.0L and K12B 1.2L petrol engines specify a multi‑rib accessory (serpentine) belt that runs over multiple pulleys, including the crankshaft pulley, alternator pulley, air‑conditioning compressor pulley, and an idler/automatic tensioner. Relevant technical sources include the Suzuki Splash/Ritz workshop manual, the Suzuki electronic parts catalogue (EPC), and 2020 application guides from major belt manufacturers (e.g., Gates and Dayco), all of which list belts, tensioners and idler pulleys for these engines. Although global Splash production ended earlier, many were first registered later, so a “2020” Splash still uses the same belt‑and‑pulley layout.

On a 2020‑registered Suzuki Splash, the drive‑belt pulley set keeps the accessory belt tracking true and transferring the engine’s rotation to key ancillaries. That means dependable alternator output to keep the battery charged and electrics happy, plus chilled air from the air‑con on hot Aussie and Kiwi days. Where fitted, the tensioner pulley maintains belt tension automatically, if the car has hydraulic power steering (less common on these), its pump sits on the same belt.

As part of routine servicing, it’s smart to inspect the belt and pulleys every service interval (roughly 10,000–15,000 km). In local conditions with heat, dust and stop‑start driving, a belt will typically last 60,000–90,000 km or 4–6 years. Pulleys and the automatic tensioner generally run longer, but many techs replace the tensioner with the belt once past 100,000 km to avoid come‑backs.

• Watch for tell‑tales: cold‑start squeal, intermittent chirps, belt glaze or cracking, frayed ribs, flickering charge light, or air‑con that cuts in/out.
• Spin-check pulleys (engine off): any roughness, wobble, play, or rusty dust near the bearing means it’s due.
• Look along the belt: misalignment or edge wear points to a bent bracket, failing tensioner or wrong-length belt.

When replacing, use quality OEM‑equivalent parts. Fit the correct rib count and length belt, reset routing exactly as per the under‑bonnet decal or service manual, and ensure the tensioner moves smoothly through its range. If the alternator uses an overrunning decoupler pulley (some do), check it while the belt is off, a failed decoupler can mimic belt slip. After refit, start the engine and observe the belt tracking, no flap, no wander, no noise. A competent DIYer with basic hand tools and a long spanner for the tensioner can manage the job, but if there’s any bearing noise or alignment doubt, a quick visit to a workshop will save headaches.

Popular questions about 2020 Suzuki Splash drive-belt pulleys

Does the “2020” Splash definitely have a drive-belt pulley setup?
Yes. Suzuki’s service manual and EPC list an accessory belt with a crank pulley, alternator and A/C pulleys, plus an idler/tensioner on K10B/K12B engines. Aftermarket catalogues (Gates/Dayco, 2020 editions) also specify belts and pulleys for the Splash/Ritz. Even if first registered in 2020, it uses the same hardware.

What noises mean the pulley or belt needs attention?
A sharp chirp on gear changes, a cold‑start squeal, or a steady whirr/rumble at idle points to a slipping belt or a dry pulley bearing. Glazed belt ribs, rubber dust, or rusty powder near a pulley are further clues. If the charge light flickers or the A/C cycles oddly, get it checked promptly.

How long does replacement take and can it be DIY?
Typically 0.7–1.2 hours for a belt, a bit longer if replacing the tensioner/idler. DIY is feasible with good access, a long spanner for the tensioner and the correct routing diagram. If there’s pulley play, misalignment, or an overrunning alternator pulley to assess, a workshop visit is the safer bet.
