Nissan Navara Engine Replacement Parts

The Navara sold in the UK has gone through distinct generations: the D22 ran roughly 1997–2004, the D40 ran 2005–2015 (with a facelift around 2010), and the D23 (also known as the NP300) arrived in 2016 onwards. The vast majority of UK D40 and D23 models use a diesel engine, most commonly the 2.5 dCi in the D40 and the 2.3 dCi twin-turbo in the D23, though always cross-check the engine code on your V5 or a VIN check before ordering. Knowing your exact engine code — rather than just the year — is the single most useful detail you can give a breaker.

The D40 facelift arrived around 2010, and while many mechanical elements carried over, ancillary components, engine mounts, and supporting hardware can differ across that boundary in ways that aren't always obvious. If both vehicles share the same engine code — typically YD25DDTi for the 2.5 dCi D40 — the core engine block is broadly from the same family, but you should confirm with the breaker against your specific registration whether brackets, sensors, and ancillaries will match before committing. Never assume a straight swap without that check.

Trim level does not affect engine fitment on the Navara — a Visia, Acenta, Tekna, or Trek of the same generation and engine code will use the same engine. What can differ between trim levels is equipment like heated seats, infotainment, or exterior styling, but none of that changes what sits under the bonnet. Match on engine code, fuel type, and gearbox type (manual or automatic), and the trim your donor vehicle came from is irrelevant.

No — the D23 NP300 uses a 2.3 dCi twin-turbo engine (code YS23DDT or similar) that is a fundamentally different unit from the 2.5 dCi (YD25DDTi) found in the D40, so the two are not interchangeable. The generations have different engine families, different mounting arrangements, and different ancillary layouts, making a cross-generation swap impractical for a standard replacement. Stick to sourcing an engine from within your own generation and matching your engine code exactly.

This is something you should confirm with your breaker and a Nissan-specialist mechanic rather than taking general guidance on, as ECU and immobiliser compatibility can depend on how the engine was removed and what control units come with it. Some used engines are supplied with ancillaries or ECUs and some are not, so it's worth asking the breaker exactly what is included and whether any coding to your vehicle will be needed. A specialist with diagnostic equipment can advise on what work is required once you have the specifics of the unit you're buying.

If both engines carry the same code — typically YD25DDTi — they are from the same engine family within the same D40 generation, which is a good starting point for compatibility. However, ancillary components, sensors, and mounting brackets can vary within a production run, so confirm with the breaker against both registrations that everything lines up before you buy. Supplying your engine code from the V5 or a VIN check gives the breaker the best chance of finding you the right unit.
