Cheap Vauxhall Cavalier Clutch Master Cylinder

Yes, but only on manual gearbox variants — the Cavalier was available with both manual and automatic transmissions, and only the manual versions use a hydraulic clutch system with a master cylinder. If your Cavalier has an automatic gearbox, it will not have a clutch master cylinder at all. When searching for this part, confirm to the breaker that your car has a manual gearbox so they can supply the correct unit.

The Cavalier Mk2 ran from 1981 to 1988 and the Mk3 from 1988 to 1995, and these are distinct generations with different underpinnings, so a straight swap between the two is not something you should assume. The engine code is the most important detail for matching the master cylinder, and even within the same generation there can be variation. Confirm compatibility against your registration with the breaker before buying.

Yes — the engine code is the most reliable guide to which clutch master cylinder you need, as different engines and fuel types (petrol or diesel) can influence the clutch hydraulic specification. The engine code is printed on your V5C or can be obtained from a VIN check, and it is the single most useful detail you can give a breaker. Do not rely on engine size alone, as the same displacement could cover more than one engine variant.

No — trim level does not affect clutch master cylinder fitment on the Cavalier. The L, GL, GLS, and CDi badges relate to interior and equipment specification rather than the mechanical clutch system. What matters is the engine code, fuel type, and whether the car has a manual gearbox, so focus on those details when speaking to a breaker.

Both years fall within the Cavalier Mk3 generation (1988–1995), so there is a reasonable chance of compatibility, but Vauxhall did make running changes to ancillary components during a production run and the exact cutoff for any such changes is something you should confirm with the breaker against your registration. Supply your engine code and registration to the breaker so they can verify the part matches before it leaves the yard.

The Vectra succeeded the Cavalier from 1995 onwards and shares some Vauxhall platform heritage, but that does not mean the clutch master cylinder will interchange — mounting arrangements and hydraulic specifications can differ even between closely related models. This is a question best put directly to the breaker, who can cross-reference part numbers against both your Cavalier's engine code and the donor Vectra's details. Never assume a cross-model fit without that verification.
