Hyundai i40 Flywheel Replacement Parts

It depends on the gearbox: i40s fitted with a manual gearbox have a conventional flywheel, whereas those with the automatic gearbox use a torque converter instead and have no flywheel. If your i40 is a manual, a used flywheel is a legitimate part to search for; if it is an automatic, you will need a different component entirely.

The Hyundai i40 ran as a single generation from 2011 to 2019, with a facelift arriving around 2015, but the core engine and gearbox combinations remained largely the same across both phases. Flywheel fitment is driven primarily by the engine code, so a pre-facelift and post-facelift car sharing the same engine code is a promising starting point for interchange. That said, whether ancillary or mounting details changed at the 2015 facelift point is something you should confirm with the breaker against your registration before buying.

Yes — the i40 was sold with both petrol and diesel engines, and a flywheel from a diesel variant will not be the correct part for a petrol-engined car and vice versa. The mass and balance of a diesel flywheel is matched to the higher torque and different firing characteristics of a diesel engine, so mixing them is not suitable. Always specify petrol or diesel, and ideally supply your engine code, when requesting a quote from a breaker.

Trim level makes no difference to flywheel fitment on the i40 — Classic, Style, Premium, and SE trims all use the same mechanical drivetrain components within each engine and gearbox combination. What matters is the engine code and whether the car has a manual gearbox, not the badge on the boot lid. A breaker may price parts from higher-spec cars differently, but the flywheel itself is the same unit.

The most useful information you can supply is your engine code, which is the single most reliable way to match a flywheel — you can find it on your V5C logbook or via a VIN check. You should also confirm that your car has a manual gearbox, since automatics do not use a flywheel, and state whether it is petrol or diesel as a cross-check. Your registration plate lets the breaker verify everything against their reference data before quoting.

Within a given engine code the flywheel is generally a consistent part, but some engines were offered with both a standard single-mass flywheel and a dual-mass flywheel depending on specification or production date, and the two are not interchangeable. The safest approach is to quote your exact engine code to the breaker and ask them to confirm the flywheel type matches your original unit. Never assume a part is correct based on engine size alone without that engine code confirmation.
