Used Peugeot 408 Radiator

The Peugeot 408 first generation ran from 2022 onwards, so there is only one generation to date and year-to-year differences within it are more likely to be down to engine code than a full generation change. Always match on engine code first — check your V5 or run a VIN check to get the exact code — and give that to the breaker rather than just quoting the year. Whether ancillary brackets or mounting points changed at any mid-production update is something to confirm with the breaker against your registration before buying.

No — the plug-in hybrid (e-EAT8) drivetrain in the 408 has a fundamentally different cooling architecture to the pure-petrol versions, so a radiator from a petrol car will not be a straight swap onto a hybrid. Always tell the breaker both your fuel type and your exact engine code so they can pull the correct unit from their stock. Never assume parts are interchangeable across petrol and hybrid variants even where the body looks identical.

For a mechanical part like a radiator, trim level — whether Allure, Allure Premium, or GT — does not determine fitment; the engine code and fuel type are what matter. A radiator from an Allure with the same engine code as a GT should physically be the same unit, though it is worth noting the breaker may supply ancillary parts (brackets, clips) that look slightly different cosmetically. Always verify engine code match with the breaker rather than relying on trim name alone.

On some Peugeot applications the radiator includes an integrated automatic transmission fluid cooler, which means the auto and manual versions are not the same part. Tell your breaker whether your 408 is manual or automatic, and give them the gearbox type alongside the engine code so they can confirm they have the right unit. Fitting a radiator without the correct cooler circuit for your gearbox type could cause problems, so this is not a detail to overlook.

The 408 shares platform and engines with other Stellantis models, so there is a chance some cooling components overlap, but the physical packaging, sizing, and mounting points can differ between body styles and model variants. Providing your 408's exact engine code to the breaker and asking them to cross-reference against their donor vehicle is the right approach rather than assuming a platform match means a part match. Never buy on platform compatibility alone — confirm directly with the breaker against your registration.

The most important detail is your engine code, which you can find on your V5 logbook or through a VIN check — this tells the breaker far more than the year or trim name alone. You should also confirm whether your car is petrol or plug-in hybrid, and whether it has a manual or automatic gearbox, as these affect which radiator is correct. With those details the breaker can match their stock accurately and flag any mounting or ancillary differences they are aware of.
