Cheap Mazda 6 Crankshaft

This question spans the boundary between the second-generation Mazda 6 (GH, 2007–2012) and the third-generation Mazda 6 (GJ, 2012–2018), and those two generations use entirely different engines, so a crankshaft from a 2010 GH-generation car will not fit a 2014 GJ-generation car. Within each generation, the engine code is what truly determines compatibility, so even among cars of the same year you need to match the code exactly. Always confirm the engine code from your V5 or a VIN check and give it to the breaker before agreeing a sale.

No — a petrol crankshaft and a diesel crankshaft are completely different components with different dimensions, stroke lengths, and bearing sizes, and they are not interchangeable under any circumstances. You must source a crankshaft that matches your exact engine code, and the engine code will confirm both fuel type and displacement. Give the breaker your engine code (found on the V5 or via a VIN check) to make sure they pull the correct unit.

Trim level has no bearing whatsoever on crankshaft fitment; the crankshaft follows the engine, not the badge or equipment level. A Sport Nav and an SE fitted with the same engine code will use exactly the same crankshaft, so you can disregard trim when searching. Focus entirely on matching the engine code, fuel type, and generation when talking to a breaker.

The GJ Mazda 6 received a facelift around 2015 that brought styling and equipment updates, but the core engine families — including the 2.0 Skyactiv-G petrol and 2.2 Skyactiv-D diesel — carried across that facelift boundary. In most cases the crankshaft from a pre-facelift GJ engine with the same engine code should be the same unit, but whether there were any mid-production internal engineering revisions is something you should confirm with the breaker against your registration number rather than assume.

Every Mazda 6 variant — whether petrol or diesel, saloon, estate (Tourer), or hatchback, across all generations — has a crankshaft, because it is a fundamental rotating component present in every internal combustion engine. There is no drivetrain or trim configuration of the Mazda 6 that lacks one. What differs is the exact specification of the crankshaft, which is determined by the engine code, so that is the detail to focus on when sourcing a used unit from a breaker.

The first-generation Mazda 6 (GG/GY, 2002–2007) and the second-generation (GH, 2007–2012) used different engine families, so a crankshaft from a GG/GY car is very unlikely to be a direct fit in a GH car even if the displacement looks similar. The engine code is the definitive test — if both cars share an identical engine code the parts may correspond, but you should always confirm this with the breaker against both registration numbers before purchasing.
