Nissan Pathfinder Engine Replacement Parts

The engine code is the single most important detail you can supply to a breaker — it sits above fuel type, year, and trim when it comes to compatibility. You'll find it on your V5C or by running a VIN check. For the R51 generation (2005–2013) the most common UK engines are the YD25DDTi 2.5-litre diesel and the VQ40DE 4.0-litre petrol; the R52 generation (2014–2021) brought the R9M 1.6-litre diesel and the V6 petrol. Always quote your exact code to the breaker rather than relying on engine size alone.

Both years sit within the R51 generation (2005–2013), so provided the engine codes match — most commonly the YD25DDTi diesel or VQ40DE petrol — fitment is broadly in the same family. However, there was a facelift in 2010 which may have brought ancillary or mounting changes mid-production, so confirm with the breaker against your specific registration before purchasing. A matching engine code gives you the strongest starting point for a successful swap.

These two years span a generation boundary — the R51 ran to 2013 and the R52 began in 2014 — and the two generations use different engine families entirely, so a straight swap across that boundary is very unlikely. Whether any specific component could be made to work is something you'd need to confirm with the breaker against your registration. Stick to sourcing an engine from within the correct generation and, crucially, with a matching engine code.

For the Nissan Pathfinder, trim levels such as Visia, Acenta, SE, and Tekna are cosmetic and equipment grades — they do not define a separate engine variant, so trim level does not affect engine fitment. What matters is the engine code, fuel type, and gearbox type (manual or automatic), not the badge on the tailgate. Bear in mind that a Tekna donor car may carry additional ancillaries or a higher specification alternator, but the core engine block will match on code; confirm any ancillary differences with the breaker.

Gearbox type can affect certain engine ancillaries, sensors, and the flywheel or flexplate fitted to the engine, so it is an important detail to pass on to the breaker alongside your engine code. In many cases the long block itself is the same, but fitting a manual-car engine into an automatic vehicle — or vice versa — may require additional parts or coding work. Always tell the breaker your gearbox type as well as your engine code and registration to avoid complications.

Fuel type is a fundamental fitment factor and a diesel engine cannot simply replace a petrol unit — the engine management systems, fuelling, and ancillaries are entirely different. Beyond the mechanical differences, ECU pairing and immobiliser coding are vehicle-specific and you should confirm how these will be handled with the breaker before proceeding. Always source a used engine matching your exact fuel type and engine code for the most straightforward replacement.
