Alfa Romeo 159 Oil Pump Replacement Parts

Every Alfa Romeo 159 has an oil pump — it is a fundamental engine component present on all variants regardless of whether the engine is petrol or diesel, turbocharged or naturally aspirated. The 159 was sold in the UK from 2005 to 2011 as a single generation with no full model-generation change, covering a range of four-cylinder and V6 engines across both fuel types. Because all internal combustion engines require pressurised oil lubrication, there is no variant of the 159 that was built without one.

Yes — the engine code is the single most important detail you need, because oil pump design follows the engine, not the badge or the year of the car. Two 159s built in the same year can have completely different engines and non-interchangeable oil pumps; for example, the 1.9 JTDm diesel (engine code 939A2) and the 2.2 JTS petrol (engine code 939A5) will not share the same pump. Check your V5C or run a VIN check to confirm your engine code before approaching a breaker.

The 159 ran as a single generation from 2005 to 2011, but there were detail engineering and ancillary changes made during that production run that could affect compatibility even within the same engine family. Provided the engine code on both donor and recipient car is identical, fitment is much more likely, but whether any mounting or ancillary changes were introduced at a specific build date is something you should confirm with the breaker against your registration rather than assume. Always supply your full registration or VIN so the breaker can check the exact specification.

Yes, fuel type matters significantly because petrol and diesel engines in the 159 are entirely different units with different oil pump designs. For instance, the 2.4 JTDm diesel and the 3.2 V6 petrol share nothing in terms of their lubrication components. Always confirm the fuel type and, more importantly, the precise engine code with the breaker to ensure you are quoted for the correct part.

No — trim level has no bearing on oil pump fitment whatsoever. Lusso, Ti, and Veloce are specification grades that relate to interior equipment, exterior styling, and features, not to the engine internals. What matters entirely is the engine code fitted to your car, which you can find on your V5C or via a VIN check, and that is what you should give to the breaker when requesting a quote.

No — body style makes no difference to oil pump fitment on the 159. The saloon and Sportwagon share the same engine options, and the oil pump is determined entirely by the engine fitted, not by whether the car has a saloon or estate body. Focus on providing the breaker with your engine code and registration, and body style can be safely ignored for this part.
