Cheap BMW X4 Radiator

The BMW X4 first generation (F26) ran from 2014 to 2018, so both years sit within the same generation, which is a promising starting point. However, fitment really comes down to engine code rather than year alone — a 2.0-litre diesel (for example, N47 or B47) and a 3.0-litre unit will typically use different radiators even within the F26 range. Check your engine code on your V5 or a VIN check, give that to the breaker, and they can confirm whether the donor part matches.

The F26 (2014–2018) and G02 (2018–present, facelifted 2021) are completely different generations built on different platforms, so a direct swap is very unlikely. The cooling systems were redesigned alongside the new architecture, and the two radiators will differ in dimensions and connection points. Always confirm against your registration with the breaker before purchasing.

Trim level alone does not affect radiator fitment — xLine, M Sport, and standard trims with the same engine code will generally use the same radiator. Where it does matter is if the trim corresponds to a different engine, for instance the M40i or M40d use higher-output units that may have uprated cooling compared to a 20i or 20d. Focus on matching the engine code rather than the badge, and note that any ancillary brackets or mounting clips can vary, so confirm those details with the breaker.

The G02 facelift arrived in 2021, and while the core platform is shared with the pre-facelift (2018–2021), mid-cycle refreshes sometimes bring changes to ancillary mounts or cooling circuit connections. The engine code is still your most reliable guide, and for like-for-like engine codes a pre-facelift radiator may well interchange — but whether any mounting or fitting changes occurred across that 2021 boundary is something you should confirm with the breaker against your registration.

Yes, fuel type matters because petrol and diesel engines run at different thermal loads and the radiator is sized accordingly, so they are not interchangeable across fuel types even in the same generation. Within fuel type, the specific engine code narrows it further — a B47 diesel and a B57 diesel, for example, are different units that may use different radiators. Always quote your engine code to the breaker alongside your registration to get the right part.

The F26 X4 shares its platform with the F25 X3, and in some cases cooling components do carry over, but this is not guaranteed across all engine variants and production dates. The safer approach is to quote your engine code to the breaker and let them cross-reference the part numbers between the two models rather than assuming visual similarity means compatibility. Never assume a part fits without the breaker confirming it against your specific registration.
