Parts for your 2025 Suzuki Splash-Thermostat

2025 Suzuki Splash thermostat — relevance, facts, and what to know

After checking technical sources, a thermostat is not relevant to a “2025 Suzuki Splash” because that model year doesn’t exist. Suzuki’s global product timelines and European media releases confirm the Splash’s production run ended in the mid‑2010s, with European sales ceasing by 2014. Maruti Suzuki also retired the closely related Ritz several years later. There are no factory technical bulletins, catalogues, or VIN ranges for a 2025 Splash. Any “2025 Suzuki Splash thermostat” listing is almost certainly a mislabelled or generic parts entry rather than a real model‑year application.

Those same technical references—Suzuki’s Electronic Parts Catalogue and the Splash/Ritz workshop manuals for K10B (1.0‑litre) and K12B (1.2‑litre) petrol engines, plus the D13A (1.3 DDiS) in some markets—do show a conventional wax‑pellet thermostat fitted to genuine Splash vehicles (2008–2014, market dependent). The manuals outline a standard engine‑cooling layout with a replaceable thermostat and housing, and typical opening temperatures in the low‑to‑high‑80s °C depending on engine code.

Why is a thermostat “not used” on a 2025 Splash? Simply because there’s no 2025 Splash. With no certified 2025 model in Suzuki’s technical literature or parts systems, there’s nothing to specify or service for that year. If someone’s searching for a Splash thermostat today, they almost always mean the 2008–2014 Splash (or the Ritz in India), and the correct approach is to select parts by engine code and VIN from those years.

• Model lifecycle: Suzuki’s published product history and European press materials show Splash production and sales wrapped up by 2014, with no subsequent relaunch carrying the Splash nameplate into 2025.
• Parts traceability: Suzuki’s Electronic Parts Catalogue lists thermostats for Splash/Ritz engines through their final VIN ranges, there are no EPC entries tied to a 2025 Splash.

If the goal is to service a genuine Splash (2008–2014), use the engine code to match the thermostat and housing, replace the O‑ring/gasket, and refill with the correct Suzuki long‑life coolant (or equivalent OAT) at the proper mix. Bleed the system with the heater on hot, and verify fan cut‑in and stable operating temperature on a road test. That’s the smart way to keep the little Suzuki running sweet as at Aussie and Kiwi cruising speeds and temperatures.

FAQs

Does a 2025 Suzuki Splash exist, and does it use a thermostat?
No. Suzuki’s own model history and European media releases show the Splash ended in the 2010s, so there’s no 2025 Splash. Older Splash models (2008–2014) do use a conventional thermostat in the cooling system.

Which thermostat fits a Suzuki Splash?
It depends on the engine code and market. The K10B 1.0‑litre and K12B 1.2‑litre petrol engines, and the D13A diesel in some regions, each have specific thermostat part numbers and housings listed in the Suzuki Electronic Parts Catalogue. Match by VIN/engine code and reuse or replace the housing as required.

What are common signs the Splash thermostat needs attention?
Slow warm‑up, fluctuating temperature, heater going cold at speed, or overheating at low speed can all point to a sticking thermostat. Some cars log a P0128 code for “coolant temperature below thermostat regulating temperature”. If confirmed, replace the thermostat, fit a new seal, refill with the correct coolant, and bleed the system to purge air.
