Second Hand Alfa Romeo 155 Oil Pump

Yes, all Alfa Romeo 155 variants have an oil pump – it is a fundamental engine component present on every petrol and diesel engine the 155 was sold with, from the 1.6 Twin Spark through to the 2.5 V6 and the 2.5 TD diesel. The specific pump you need depends on which engine is fitted to your car, not the trim level or body style. Always confirm the engine code from your V5 or a VIN check before ordering.

The Alfa Romeo 155 ran from 1992 to 1997, with a facelift introduced in 1995 that brought styling and some specification changes. Engine codes largely carried across the facelift, so a pump from the same engine code can potentially cross that boundary, but ancillary and mounting details can change mid-production, so you should confirm compatibility with the breaker against your exact registration rather than assume it fits simply because the engine name matches. The engine code on your V5 is the single most useful detail to give the breaker.

Yes, the 1.8 and 2.0 Twin Spark engines carry different engine codes and are internally distinct, so their oil pumps are not the same part. When contacting a breaker, quote your exact engine code rather than just the capacity, as this removes any ambiguity and lets the breaker pull the correct pump from their stock. Never assume that similar displacement means the parts are interchangeable.

Trim level has no bearing on oil pump fitment whatsoever – the pump follows the engine, not the badge or equipment level. A Super-spec 155 with the same engine code as a base-model 155 will use an identical oil pump. Concentrate on supplying the breaker with your engine code and fuel type, and ignore trim differences entirely.

No – the 2.0 four-cylinder and 2.5 V6 are completely different engines with different blocks, so their oil pumps are not interchangeable. The V6 pump is specific to that engine code and is generally a different size and design to accommodate the V6's architecture and lubrication demands. Always match the pump to the exact engine code of your vehicle.

The most important detail is your engine code, which you can find on your V5C registration document or via a VIN check – this tells the breaker exactly which engine variant your 155 has and is far more reliable than quoting the badge or year alone. You should also confirm your fuel type (petrol or diesel) and the year of your vehicle, as these help the breaker cross-reference their stock. Note that ancillary fitting details can vary mid-production, so always ask the breaker to verify the pump against your registration before purchasing.
