Used Mazda CX-30 Radiator

The CX-30 has been a single-generation model since its UK launch in 2019, so a 2021 and a 2023 car share the same fundamental architecture — but fitment of a used radiator still depends primarily on matching the engine code, which you'll find on your V5 or via a VIN check. Mazda did introduce running production changes during this period, so whether the radiator mounting and ancillary connections are identical across those years is something to confirm with the breaker against your registration. Never assume a year-to-year swap is guaranteed without that check.

The CX-30's Skyactiv-G petrol engines and the M Hybrid mild-hybrid variants use related but not necessarily identical cooling setups, and the engine code is the single most useful detail here rather than the MHEV badge alone. Supply your exact engine code to the breaker — not just 'petrol' or 'mild-hybrid' — so they can match the correct unit. Assuming a standard petrol radiator crosses straight over to an MHEV without checking is a risk not worth taking.

Trim level — whether that's SE, SE-L, GT Sport, or GT Sport Tech — does not affect radiator fitment on the CX-30; the radiator follows the engine and gearbox combination, not the badge on the tailgate. What does matter is your engine code and whether you have a manual or automatic gearbox, so have those details ready when you contact a breaker. You may find cosmetic differences such as brackets or clips if ancillary parts differ between build dates, so confirm the full spec with the breaker against your registration.

No — the Skyactiv-D diesel and Skyactiv-G petrol engines are fundamentally different, and their cooling system components are not interchangeable. Always match the radiator to your specific engine code, not just the body of the car. Make sure you give the breaker your engine code so they source the correct unit for your fuel type.

It can do, because automatic gearboxes on the CX-30 often use the radiator to cool transmission fluid via an integrated cooler, meaning the automatic radiator may have additional ports or connections that a manual-gearbox radiator does not. Always tell the breaker whether your car is a manual or automatic alongside your engine code, as supplying both details is the safest way to get the right match. Fitting an incompatible unit risks either poor cooling or transmission damage, so don't guess.

The CX-30 has not had a formal full facelift with a confirmed new generation boundary in the way some Mazda models have, but Mazda made incremental updates throughout production from 2019 onwards and component specifications can vary across build years. The most reliable approach is to match on engine code and gearbox type first, then confirm with the breaker using your registration whether the radiator from a specific donor year is compatible with your 2019 car. Quoting your registration and engine code to the breaker is the safest route rather than assuming all 2019-onwards cars share identical radiator specifications.
