Nissan Pathfinder Oil Cooler Replacement Parts

Yes, oil coolers were fitted to certain Pathfinder variants, most notably the 2.5 dCi diesel engine (engine code YD25DDTi) found in the R51 generation (2005–2014), where an oil-to-water cooler is part of the engine's thermal management system. Petrol-engined Pathfinders are less likely to carry a dedicated engine oil cooler as standard, though some markets and variants did include one. If you have a petrol R50 or R51, confirm with the breaker whether your specific engine variant was fitted with one before ordering.

Both years fall within the R51 generation (2005–2014), so there is a reasonable chance of compatibility, but Nissan made running production changes to ancillary components and mounting arrangements during this generation, including around the 2010 facelift period. The engine code is the most important detail — if both vehicles share the same YD25DDTi code, the core unit is likely the same, but confirm the specific part number and mountings with the breaker against your registration to be sure. Never assume a direct swap without that check.

The R51 Pathfinder received a facelift around 2010, and while the YD25DDTi diesel engine carried across, ancillary and mounting details can change at a facelift boundary. Name the boundary to the breaker and ask them to cross-reference both registrations, as coolant pipe routing or bracket positions may differ even if the core cooler looks identical. The engine code from your V5 or a VIN check is the single most useful piece of information you can give them.

No — trim level does not affect oil cooler fitment on the Pathfinder; the cooler is determined by engine code and fuel type, not by whether your vehicle is a Tekna, Aventura, or any other trim. All these trims were available with the same YD25DDTi diesel engine in the R51 generation, so the oil cooler specification is shared across them. You may simply notice cosmetic differences between donor and your vehicle, but none of those affect whether the cooler itself will fit.

Petrol-engined Pathfinders, including the V6 petrol variants in the R51 generation, are less commonly fitted with a dedicated engine oil cooler as standard compared to the diesel models, and some may not have one at all. If your petrol Pathfinder does not currently have an oil cooler, it is worth checking with a Nissan dealer or a breaker whether one was ever fitted to your specific engine variant before searching for one. Confirm against your registration and engine code, as fitting an oil cooler that was not originally specified could require additional modification.

The most important detail is your engine code, which you can find on your V5 logbook or via a VIN check — for diesel R51 Pathfinders this is typically YD25DDTi, and giving this to the breaker is far more useful than quoting your model year alone. You should also confirm your fuel type, gearbox type (manual or automatic), and your full registration so the breaker can cross-reference the exact specification. Trim level and body colour make no difference to fitment and can be ignored for this part.
