Cheap Mazda CX-5 Radiator

The CX-5 runs in two main generations: the first generation (Mk1) covered 2012 to 2017, and the second generation (Mk2) runs from 2017 onwards, with a facelift around 2021. Radiators from the Mk1 and Mk2 are not the same, so always tell the breaker which generation yours is – ideally with your registration so they can confirm against the exact build. Never assume a radiator from one generation will drop straight into the other.

This question sits right across the Mk1-to-Mk2 boundary: 2015 is Mk1, while 2017 marks the start of the Mk2, so the two are from different generations and the radiator is unlikely to be a straight swap. Even if the engine code is the same across both years, mounting points and ancillary connections may differ between generations, so you should confirm compatibility with the breaker against your full registration before buying. The engine code from your V5 or a VIN check is the most useful detail to give them.

Yes, fuel type matters: the 2.0 and 2.5 petrol engines and the 2.2 Skyactiv-D diesel each have different cooling demands, and the radiators are not interchangeable between fuel types. Always confirm your engine code (found on your V5C or via a VIN check) with the breaker, as this is the single most reliable way to make sure they pull the right unit. Quoting just 'petrol' or 'diesel' without the engine code leaves too much room for a mismatch.

Gearbox type can affect the radiator because automatic transmissions often use an integrated transmission oil cooler built into the radiator, which manual cars do not need. Make sure you tell the breaker whether your CX-5 is manual or automatic so they can match the correct unit. Fitting an automatic radiator to a manual car (or vice versa) is unlikely to be a straightforward swap, so confirm this detail before agreeing a purchase.

Trim level – whether SE, SE-L, Sport, GT Sport, or any other badge – does not affect radiator fitment; what matters is the engine code, fuel type, gearbox, and which generation the car is. A radiator from an SE with the same engine as your SE-L is mechanically the same part, so do not pay a premium or reject a part based on trim alone. The only differences you might notice between trim-sourced dismantled cars are ancillary extras nearby, but the core radiator itself follows the engine, not the badge.

Give the breaker your full registration number and, ideally, the engine code from your V5C or a VIN check – the engine code is the single most useful detail for matching a mechanical part like a radiator. Also confirm your fuel type, gearbox type (manual or automatic), and the generation of your car (Mk1 2012–2017 or Mk2 2017-on). A reputable breaker will cross-reference these details against the donor vehicle before supplying the part, but fitment is never guaranteed on used parts, so ask them to confirm everything before you commit.
