This Koyorad radiator suits Nissan Navara D40 YD25 automatic models with a core size of 600 by 686 by 36 millimetres. This gear keeps the 2.5 litre diesel steady when you tow or crawl in low range where airflow drops. This setup uses an integrated auto transmission cooler so the gearbox stays in its comfort zone on long climbs or sand work.

This radiator drops into Thailand built Navara D40 front panels that match the NIS061PACAD2K pattern. This core size gives plenty of fin area for outback heat without needing custom brackets or hoses. This kit lines up with factory fan shrouds and hose positions so the usual driveway tools handle the job. This is a smart buy if your original core is blocked or leaking and you want the cooling back where it should be.

Q: Does this radiator fit manual transmission Navara D40 models?

No, this radiator suits automatic transmission models only. The unit includes an integrated transmission cooler designed for auto gearbox fluid. Manual D40 models usually run a different tank configuration without this cooler. Always match the transmission type before ordering to avoid hose and fitting issues.

Q: Is this radiator suitable for all Navara D40 build locations?

No, it is specified for Thailand-built Navara D40 YD25 models. Different factories can use different radiator mount patterns and hose positions. This unit matches the Thailand chassis layout linked to the NIS061PACAD2K reference. Check your build plate or VIN details to confirm origin before purchase.

Q: Can this radiator be used with the factory fan shroud and hoses?

Yes, it is configured to align with standard fittings on compatible vehicles. The core height, width and tank layout match the original-style Navara D40 automatic radiator. This means the shroud, upper and lower hoses and transmission lines should locate in their usual positions. Inspect old components for wear and replace if perished.

Q: Does the radiator include coolant or new hoses in the box?

No, the listing covers the radiator assembly only. Coolant type and volume need to match Nissan Navara specifications supplied separately. Hoses, clamps and caps are treated as service parts and should be sourced as required. Using fresh coolant and sound hoses helps the new core perform at its best.
