Used Hyundai Tucson Crankshaft

The third-generation Tucson (Mk3) ran from 2015 to 2021, with a facelift in 2018, so both years sit within the same generation — but whether the crankshaft crosses that 2018 facelift boundary depends entirely on the engine code, not the year alone. If both vehicles share the same engine code (found on your V5 or via a VIN check), the chances of compatibility are much stronger, but you should confirm with the breaker against your exact registration before buying. Never assume a year-to-year match without the engine code to back it up.

The Mk2 and Mk3 Tucson are entirely different generations with different engine families, so a crankshaft from a Mk2 is very unlikely to fit a Mk3. Engine codes changed substantially between generations, and the crankshaft is machined to precise tolerances specific to each engine block. Always match by engine code rather than model name, and confirm with the breaker against both registrations.

No — trim level has no bearing on crankshaft fitment whatsoever. The crankshaft is determined entirely by the engine code, not by whether the car is a S, SE, Premium or Premium SE. What does matter is fuel type (petrol or diesel) and the specific engine code on your V5, as different engine variants within the same trim range can use different crankshafts. Strip away the badge and focus on the engine code when speaking to a breaker.

No — a 1.6-litre diesel and a 2.0-litre diesel are completely different engines with different block dimensions, stroke lengths and crankshaft specifications, so they are not interchangeable. You must match the crankshaft to the exact engine code, not just the fuel type or broad displacement. Check your V5 or run a VIN check to confirm your engine code, and pass that to the breaker so they can source the correct part.

The Mk4 Tucson launched in 2021 as an entirely new generation with new engine architectures, including mild-hybrid and hybrid variants not found in the Mk3, so a crankshaft from a Mk3 (2015–2021) would not be expected to fit. Even if the fuel type appears similar, the engine codes differ between generations and the internal dimensions will not match. Confirm your Mk4 engine code via your V5 and supply it to the breaker so they can source from the correct engine family.

No — petrol and diesel engines are fundamentally different in design, with different bore sizes, stroke measurements and crankshaft dimensions, so a petrol crankshaft will not fit a diesel engine even if the vehicles are the same year and generation. Fuel type is one of the key fitment filters alongside the engine code. Always confirm the exact engine code from your V5 and make clear to the breaker whether you need a petrol or diesel crankshaft.
