Parts for your 2024 Suzuki Splash-Head gasket

2024 Suzuki Splash head gasket — purpose, care and replacement

Yes, the Suzuki Splash uses a head gasket. Technical documentation for the Splash platform (A1G/RB) confirms a “cylinder head gasket” for all factory engines. The Suzuki K10B 1.0-litre and K12B 1.2-litre petrol engine service manuals detail head-gasket fitment and head-bolt torque sequences, and the Diesel D13A DDiS service information specifies the same sealing component. Suzuki’s Electronic Parts Catalogue for the Splash also lists the head gasket in the engine section. While the Splash wasn’t newly built in 2024, plenty are still on Aussie and Kiwi roads, and every one of those engines relies on its head gasket.

A head gasket sits between the engine block and cylinder head, sealing combustion pressure and keeping engine oil and coolant in their own passages. In normal running it handles extreme heat and pressure, so correct installation and cooling-system health are critical. When a gasket starts to fail, owners may notice overheating, a sweet-smelling steam from the exhaust, milky residue under the oil filler cap, bubbling in the coolant reservoir, or rough running on cold start.

There’s no set time or kilometre interval to replace a head gasket on a Splash. It’s a “replace on failure” job, but smart servicing can dramatically reduce the chances of drama. Keeping the cooling system in top nick is the big one: fresh, correct-spec coolant, a sound radiator cap, a clean radiator, and a thermostat that opens on cue. Under the bonnet, look for any coolant weeps or oil leaks that could point to early issues.

If replacement is needed, a proper workshop procedure matters. The Splash engines use torque-to-yield head bolts, so new bolts are required. The aluminium head should be checked for flatness, pressure-tested, and lightly skimmed if out of spec. A high-quality MLS (multi-layer steel) gasket matched to the exact engine code should be used, and the bolt-tightening order and angles from the Suzuki service manual must be followed to the letter.
