Vauxhall Cavalier Crankshaft Replacement Parts

Yes, every petrol and diesel engine variant of the Vauxhall Cavalier has a crankshaft — it is a core internal engine component present in all internal combustion engines regardless of fuel type, gearbox, or body style. The Cavalier was sold in the UK across two main generations: the Mk2 (1981–1988) and the Mk3 (1988–1995), covering a wide range of engines from 1.3-litre petrols through to the 2.0-litre 16v and the 1.7-litre diesel. Every one of those engines contains a crankshaft, so the question of fitment comes down entirely to which specific engine is in your car.

The Mk2 and Mk3 Cavalier generations used substantially different engine families, and crossing the 1988 generation boundary for an internal part like a crankshaft is not something that can be confirmed in general terms. Even where similar engine displacements were carried across both generations, internal specifications such as stroke, journal diameter, and reluctor arrangement can differ. You must confirm cross-generation compatibility directly with the breaker, quoting the engine code from your V5 or a VIN check against the engine code of the donor vehicle.

Trim level makes no difference to crankshaft fitment — the crankshaft is determined entirely by the engine fitted, not by whether the car is a GL, GLS, CD, or SRi. Two Mk3 Cavaliers with the same engine code will have the same crankshaft regardless of trim, so do not filter your search by trim name. What matters is the engine code, which you will find on your V5 or via a VIN check, and that is the detail to give your breaker.

Yes, fuel type is critical — a petrol crankshaft and a diesel crankshaft are not interchangeable even if the displacement sounds similar, because diesel engines run at higher compression ratios and the crankshaft is built to different specifications. Always tell the breaker your exact engine code as well as your fuel type, since the engine code is the most reliable way to ensure the correct part is matched. A 1.7 diesel crankshaft, for example, is a completely different component to the 1.8 or 2.0 petrol units.

The gearbox type itself does not change the crankshaft specification, as the crankshaft is internal to the engine and not directly determined by whether the car has a manual or automatic transmission. However, certain engine and gearbox combinations were paired together from the factory, so the engine code remains the key identifier to give your breaker rather than the gearbox type. Confirm the full engine code from your V5 or a VIN check and pass that directly to the breaker when requesting a quote.

Both years fall within the Mk3 generation (1988–1995), so you are working within the same broad platform, but whether a crankshaft from a 1993 or 1994 2.0-litre engine is a direct match for your 1990 unit depends on the specific engine codes involved, as Vauxhall made running production changes during this generation. The engine code on your V5 or from a VIN check is the single most important detail to supply, and you should ask the breaker to match it to the engine code of the donor car rather than going on year alone. Never assume year-to-year compatibility within a generation without the breaker confirming the codes align.
