Second Hand Nissan Pathfinder Water Pump

The R51 and R52 Pathfinder are entirely different generations with different engine families, so a water pump from one will not fit the other. The R51 used engines including the 2.5 dCi diesel and the 4.0-litre V6 petrol, while the R52 moved to different petrol units, meaning the pumps are not interchangeable across that 2012 generation boundary. Always confirm the exact engine code from your V5 or a VIN check before ordering, and ask the breaker to verify compatibility against your registration.

Both sit within the R51 generation (2005–2012), so fitment is broadly determined by engine code rather than year – a pump from the same engine variant should be compatible, but Nissan did make ancillary and mounting changes at various points within the R51 run. Confirm with the breaker against your specific registration and engine code, as a mid-production revision could affect whether the pump mounts and seals correctly.

Yes, all Nissan Pathfinder variants sold in the UK use a conventional liquid-cooled internal combustion engine and therefore have a water pump as a standard part of the cooling system. This applies across all generations and both the diesel and petrol engine options, so you can be confident the part exists on your vehicle. Simply make sure you match the pump to your engine code, as the diesel and petrol pumps are completely different items.

Trim level – whether SE, SVE, Tekna, or any other – has no bearing on the water pump, because the pump is dictated entirely by the engine fitted. Nissan offered the same core engine options across trim grades on the Pathfinder, so a pump from an SE with the matching engine code is the same as one from a Tekna with the same engine. Just focus on the engine code and fuel type when speaking to the breaker, and ignore the trim badge entirely.

The 2.5 dCi engine (YD25DDTi) is the key identifier, and pumps from the same engine code are generally the right starting point across the R51 generation (2005–2012). However, production changes can affect ancillary components including the water pump mounting or drive arrangement at points not always publicly documented, so treat year as a secondary factor and have the breaker confirm against your full registration. Providing your engine code from the V5 will give the breaker everything they need to verify the part before it is sent.

The YD25DDTi diesel engine was shared across several Nissan models including the Navara and some X-Trail variants, so there is genuine cross-model potential for the water pump. However, ancillary differences and engineering revisions mean you cannot assume a Navara pump is a direct drop-in without checking, and this is exactly the kind of confirmation a breaker can make against both registrations. This is worth raising with the breaker as it can widen the pool of available used parts and potentially reduce cost.
