Vauxhall Cavalier Fuel Injector Replacement Parts

The Cavalier did use carburettors on earlier and lower-spec engines, but fuel-injected variants were definitely offered — particularly from the Mk3 generation (1988–1995) onwards, where engines such as the 2.0i used port fuel injection. So injectors do exist on this model, but only on the petrol injection variants, not the carburettor-fed or diesel engines.

Both sit within the Cavalier Mk3 generation (1988–1995), so the starting point is promising, but the key detail is the engine code — not the year. Provide your engine code from the V5 or a VIN check and ask the breaker to match it precisely, as injector specification can vary across the production run even within the same generation. Never assume year-to-year compatibility without confirming the engine code matches.

Trim level does not drive injector fitment — what matters is the engine code, which can be shared across GL, CDi, GLS, and SRi variants if they run the same engine. The SRi may carry a higher-output tune of the same basic engine family, so confirm the engine code matches exactly rather than relying on the badge. A breaker will cross-reference by engine code, so have that detail ready.

The Mk2 (1981–1988) and Mk3 (1988–1995) are separate generations with different engine families, so a straight swap across that boundary is unlikely to be straightforward. Injector design, flow rate, and connector type can all differ between generations. Route this question directly to the breaker with both engine codes and let them confirm compatibility — do not assume generation crossover parts are interchangeable.

Body style makes no difference to injector fitment — the injector follows the engine, not the body. A hatchback and an estate with the same engine code will use the same injector. Focus on supplying your engine code and fuel type to the breaker rather than mentioning the body style.

This is something you should confirm with your breaker or a specialist rather than assume either way, as ECU pairing and any immobiliser considerations depend on the specific vehicle and setup. On older Cavaliers the electronics are generally less complex than on modern vehicles, but it is still worth raising the question before purchase. A good breaker will be able to advise based on your registration and the donor vehicle details.
