Second Hand Nissan Interstar Oil Pump

Every Nissan Interstar has an oil pump regardless of variant — it is a fundamental component of any internal combustion engine and is present on all petrol and diesel versions of the Interstar. The Interstar was sold in the UK predominantly with diesel engines (the 2.2 dCi and 2.5 dCi units), and each of those engines has its own oil pump internally. So you are in the right place searching for this part.

The Nissan Interstar was produced as a single generation running from approximately 2002 to 2010, based on the Renault Master platform, so there is no separate generation boundary to cross in the way there would be on a multi-generation model. However, the 2.2 dCi engine used in earlier production was replaced by the 2.5 dCi unit as the range progressed, and these are different engines with different oil pumps that will not interchange. Always confirm the engine code on your V5 or via a VIN check and supply it to the breaker — that is the detail that determines which pump fits, not the year alone.

Yes — the 2.2 dCi (engine code G9T) and the 2.5 dCi (engine code G9U) are different engine families, and the oil pumps are not interchangeable between them. When searching for a used oil pump, make sure the breaker matches your exact engine code rather than just the van's year or body size. Check your V5 registration document or ask for a VIN decode to confirm which engine code you have before ordering.

No — trim level has no bearing on the oil pump fitted to your Interstar. Whether your van is a basic panel van or a higher-specification variant, the oil pump is determined entirely by the engine code (G9T for the 2.2 dCi or G9U for the 2.5 dCi) and not by any trim or body-style differences. Give the breaker your engine code and registration and they will be able to identify the correct unit.

The Nissan Interstar, Renault Master (second generation, 1998–2010), and Vauxhall Movano (first generation, 1998–2010) are all based on the same platform and share the same dCi engine families, so there is a good chance the oil pump will cross over if the engine codes match. However, there can be ancillary or supplier variations across the production run, so you should confirm the specific part numbers with the breaker against both your registration and the donor vehicle's registration before buying. This cross-compatibility is worth asking about as it can open up more available used stock.

A used oil pump can be a cost-effective choice, but it is worth asking the breaker about the mileage and service history of the donor vehicle where known, and checking that the part shows no visible wear to the rotors or housing. Supply your engine code (G9T or G9U) and your registration to the breaker so they can confirm compatibility directly — do not rely on year alone as engine changes occurred within the production run. A reputable UK breaker should be able to advise further once they have your details.
