Parts for your 2019 Suzuki Splash-Coolant

2019 Suzuki Splash coolant — what it does and how to look after it

Coolant is absolutely relevant and used on the 2019 Suzuki Splash. The Splash’s petrol and diesel engines (K10B 1.0L, K12B 1.2L, and 1.3 DDiS in some markets) are liquid-cooled and rely on ethylene-glycol–based antifreeze. This is documented in Suzuki technical literature including the Splash Owner’s Manual (EU), Suzuki service manuals for K10B/K12B cooling systems, and the Maruti Ritz (Splash) workshop manual, all of which specify a glycol coolant with corrosion inhibitors suitable for aluminium engines.

In everyday driving, coolant carries heat away from the engine to the radiator, stops the mix from freezing in winter and boiling in summer, guards against internal corrosion, and helps the heater work properly. Without the right coolant at the right concentration, the Splash can overheat, corrode from the inside out, or develop leaks and water pump issues.

For servicing, the Splash is typically filled with Suzuki Long Life Coolant (green) or Suzuki Super Long Life Coolant (blue). The safe bet is to match what’s already in the car and avoid mixing types. A 50/50 premix with demineralised water is the common ratio for year-round protection across Australia and New Zealand. If switching types or the coolant looks rusty, sludgy, or contaminated, a full flush and refill is the way to go.

Replacement timing depends on what’s fitted. Suzuki’s service literature for this engine family indicates:

• Super Long Life Coolant (blue): up to 10 years/160,000 km initially, then about every 5 years/80,000 km.
• Long Life Coolant (green): about every 2–4 years or 40,000–60,000 km.

Always follow the vehicle’s maintenance schedule or coolant label under the bonnet.

Quick checks and tips:

• Check level only when the engine’s cold, top up with the correct premix to the “FULL” mark on the reservoir.
• If topping up often, inspect for leaks at hoses, radiator, water pump and the heater core, a sweet smell or damp carpets can be a giveaway.
• After a change, run the heater on HOT and let the engine reach fan cut-in to purge air, recheck the level once it cools.
• Dispose of old coolant responsibly, it’s toxic to pets and wildlife.

This simple coolant care helps the Splash run cooler, cleaner and more reliably across Aussie and Kiwi conditions.

What coolant type does a 2019 Suzuki Splash use?

It uses an ethylene-glycol, silicate-free long-life coolant suitable for aluminium engines. Many Splash models were filled with Suzuki Super Long Life Coolant (blue) from factory, while others use Suzuki Long Life (green). Match the colour/type already in the system or follow the owner’s handbook and cap labels.

How often should the coolant be changed?

As a guide, blue Super Long Life can go up to 10 years/160,000 km initially, then about every 5 years/80,000 km. Green Long Life is typically every 2–4 years or 40,000–60,000 km. If the coolant looks discoloured, you’re topping up frequently, or the heater performance is patchy, bring the change forward.

How much coolant does it take?

Expect roughly 4–6 litres depending on engine and market spec. If doing a driveway change, have 6 litres of the correct premix on hand to allow for a proper flush and bleed. Always verify the exact capacity in the owner’s manual or service data for the specific engine code.
