Used Mazda 6 Radiator

Both years sit within the second-generation Mazda 6 (GH), which ran from 2007 to 2012, so they share the same platform and cooling architecture — engine code is the key detail, so make sure both cars carry the same engine code (found on your V5 or a VIN check) before assuming they'll swap straight over. If the engine codes match, fitment is very likely, but confirm with the breaker against your registration as there can be ancillary and mounting changes within a generation that aren't always documented publicly. Never assume fitment is guaranteed on a used part.

The third-generation Mazda 6 (GJ) launched in 2013, replacing the second-generation GH that ran from 2007 to 2012, and these are distinct platforms with different engine families, so a radiator from the GH generation will not cross straight over to a GJ car. Always match by generation first, then by engine code. Confirm the exact part compatibility with the breaker against your registration before purchasing.

Trim level does not affect radiator fitment — SE, SE-L, Sport Nav, and GT Sport are all equipment and cosmetic distinctions rather than mechanical ones, and the radiator follows the engine, not the badge. What matters is your engine code, fuel type (petrol or diesel), and whether you have a manual or automatic gearbox, as these can influence cooling requirements. Confirm the correct unit with the breaker against your registration to be sure.

The third-generation Mazda 6 (GJ) received a facelift in 2018, and while the core engines carried over, there can be ancillary and mounting changes introduced at a facelift point that affect whether parts interchange directly. Name the generation boundary clearly when speaking to the breaker — tell them your car is the post-2018 GJ facelift — and ask them to confirm fitment against your registration rather than assuming pre- and post-facelift radiators are identical. Engine code remains the single most useful detail you can supply alongside your reg.

Different engines typically require different radiators, as cooling demands vary significantly between a 2.0 petrol and a 2.2 diesel, and the two units may differ in size, flow rate, or connection layout. Even within the same generation, always match by engine code rather than by year or model name alone — your V5 or a VIN check will show your exact engine code. Let the breaker check both registrations before committing to a purchase.

It can matter — automatic gearboxes sometimes use a transmission oil cooler integrated into or plumbed through the radiator, meaning the automatic version of a radiator may have additional ports that a manual-spec unit lacks. If your Mazda 6 is an automatic, make sure you source a radiator from an equivalent automatic car, and confirm this with the breaker against your registration. Supplying your engine code, fuel type, and gearbox type together gives the breaker everything they need to find the right match.
