Parts for your 2023 Suzuki Splash-Radiator hose

2023 Suzuki Splash radiator-hose: what it does, and how to look after it

Technical sources confirm the Suzuki Splash (also sold as Maruti Ritz) uses conventional upper and lower radiator hoses on its K10B 1.0‑litre and K12B 1.2‑litre petrol engines. The Suzuki Splash/Ritz workshop manual (Cooling System section for K10B/K12B) and the Suzuki Electronic Parts Catalogue list the upper and lower radiator hoses, clamps and related cooling hardware for these engines. While the Splash wasn’t produced as a 2023 model year—production ended globally mid‑2010s per manufacturer model guides and industry references—the part itself is very much relevant to any Splash on the road, because its liquid‑cooled petrol engines rely on these hoses to circulate coolant between the engine and radiator.

On a 2023 Suzuki Splash listing, the radiator‑hose is the flexible pathway that carries hot coolant from the engine to the radiator (upper hose) and returns cooled fluid back to the engine (lower hose). Without it, the Splash would overheat in no time. These hoses see constant heat, pressure, and vibration, so they naturally harden, soften, or crack with age—especially in Aussie and Kiwi summers.

For servicing, it’s smart to inspect the radiator hoses at every routine service interval. Look for: soft or spongy sections, surface cracking, swelling near the ends, oil contamination, seepage at clamps, or crusty dried coolant. Any of those signs means it’s time to replace. As a rule of thumb, many owners replace original hoses around 6–8 years or 100,000–120,000 km, but environment and driving style matter—go earlier if in doubt.

When replacing, choose hoses that match the Splash’s engine code (K10B or K12B) and follow workshop‑manual guidance for clamp re‑use or replacement. Constant‑tension clamps are ideal, and the hose mustn’t kink or rub on brackets. Only work on a cold engine, release pressure carefully, catch and dispose of old coolant responsibly.

After fitting, refill with the correct Suzuki‑spec long‑life coolant at the proper mix (commonly 50/50 premix) and bleed the system so there’s no trapped air—air pockets can cause hot spots and erratic heater performance. Recheck the coolant level and clamp seating after the first decent drive. Keeping the Splash’s radiator‑hose in top nick helps the water pump, thermostat, and radiator do their jobs, preventing overheating and costly repairs.

Handy reminders for owners in Australia and New Zealand:

• Inspect at every service, replace at the first sign of deterioration.
• Use the correct engine‑specific hose and fresh clamps.
• Refill with the right coolant and bleed properly, recheck levels after a drive.

Popular questions about 2023 Suzuki Splash radiator‑hose

Does a 2023 Suzuki Splash actually exist, and does it have a radiator hose?
There wasn’t a 2023 model‑year Splash, production ended earlier. However, every Suzuki Splash on the road uses upper and lower radiator hoses as part of its liquid‑cooling system, so the part remains relevant for servicing and replacements.

How often should Splash radiator hoses be replaced in AU/NZ conditions?
Inspect at each service and plan for replacement around 6–8 years or 100,000–120,000 km if original. Heat, age, and oil exposure accelerate wear—if you see swelling, cracking, or leaks, replace immediately rather than waiting for a set interval.

What coolant should be used after changing a Splash radiator hose?
Use a Suzuki‑approved long‑life coolant in the correct concentration (often 50/50 premix). After refilling, bleed the system to remove air and top up the overflow bottle to the proper mark. Recheck levels and hose clamps after the first trip.
