Parts for your 2021 Suzuki Splash-Thermostat housing

2021 Suzuki Splash thermostat housing — is it relevant?

A thermostat housing isn’t relevant to a 2021 Suzuki Splash because there’s no 2021 model Splash to begin with. Suzuki wrapped up European Splash production around 2014, and its Indian-market sibling (the Maruti Suzuki Ritz) was phased out by 2016. That means any listing that pairs “2021” with “Suzuki Splash” is a catalogue or filter mismatch rather than a real, model-year-correct fitment.

This call is based on core references used across the trade: Suzuki’s model history and market announcements show the Splash exiting European line-ups mid‑2010s, while Maruti Suzuki confirmed the Ritz discontinuation in 2016. Suzuki’s Electronic Parts Catalogue (EPC) for Splash model years 2008–2014 (and Ritz up to 2016) does list a thermostat housing assembly for the K10B 1.0‑litre and K12B 1.2‑litre engines, but nothing for a 2021 Splash because that model year doesn’t exist. Workshop manuals for the K‑series engines also describe the thermostat housing on the cylinder head with the thermostat insert and coolant temp sensor provisions.

If someone’s paperwork shows “first registered 2021”, that’ll be a compliance or re‑registration date for an older Splash, not a 2021 build. Under the bonnet, those cars still use a conventional thermostat housing, but parts should be chosen by VIN, engine code (K10B/K12B), and actual build year. Don’t rely on 2021 filters in parts search tools, as they’ll steer you off course.

• Suzuki model history and range updates: Splash ended in Europe mid‑2010s, replaced in the city‑car slot.
• Maruti Suzuki communications: Ritz (Indian Splash) discontinued in 2016.
• Suzuki EPC and K‑series engine manuals: thermostat housing present on Splash/Ritz through last production years, none for a 2021 model year.

Bottom line: thermostat housings absolutely exist on genuine Splash/Ritz engines, but there’s no such thing as a 2021 Splash, so any “2021 Splash thermostat housing” reference isn’t applicable. Match the part to the real build year and engine code, and you’ll be sweet.

Popular questions about a 2021 Suzuki Splash thermostat housing

Does a 2021 Suzuki Splash have a thermostat housing?
No. There’s no 2021 model Splash. If your vehicle is labelled as a Splash and registered in 2021, it’s almost certainly an earlier build. Those use a standard thermostat housing on K10B or K12B engines, so source parts by VIN and engine code.

What should be ordered if a site lists a 2021 Splash thermostat housing?
Ignore the 2021 filter and search by VIN or by 2008–2014 Splash (or up to 2016 Ritz) with K10B/K12B. The correct housing typically includes the outlet neck, thermostat seat, sensor port, and an O‑ring or gasket—confirm specifics in the EPC.

Could a Splash share a thermostat housing with another Suzuki, like a Swift?
Some K12B components cross over, but thermostat housing part numbers can vary by market and emissions spec. Always cross‑check via VIN in the Suzuki EPC and replace the seal and coolant to spec when fitting.
