This Koyorad radiator fits Nissan Navara D40 YD25 manual models from 2008 on with a core size of 600 x 686 x 36 mm that keeps the 2.5L diesel in its comfort zone on long pulls. The setup handles slow crawl work and highway running where factory cooling starts to feel stretched. The dimensions give the engine a steady temperature window when you load the ute with tools or touring gear.

The core height of 600 mm and width of 686 mm give decent face area without crowding the grille or fan shroud. The 36 mm thickness keeps coolant volume up while still letting air move through behind bars and driving lights. The radiator sits as a smart buy if your original unit is tired and you want factory-spec cooling for Aussie heat without messing around with custom mounts.

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

No, this radiator is listed for manual transmission (M/T) Navara D40 YD25 models from 2008 onwards. Auto models often use different cooler provisions and mounting points. Matching the transmission type avoids hose and line routing issues. Always check your build plate and existing radiator before ordering.

Q: Is this radiator suitable for Thailand-built Navara D40 only?

Yes, the listing specifies Thailand-built Navara D40 YD25 2.5L diesel models. Different build locations can use different radiator designs and mount layouts. Using the correct Thailand spec helps the shroud, fan and brackets line up. Check your VIN plate or compliance label for build origin.

Q: Can I pair this radiator with the factory fan shroud and hoses?

Yes, the core dimensions of 600 x 686 x 36 mm and application listing are intended to match the factory cooling setup. Keeping the original shroud and hoses maintains designed airflow across the core. This also keeps under-bonnet clearances consistent. Always inspect existing hoses and clamps for wear during installation.

Q: Is this radiator suitable for towing and loaded touring?

The 600 mm height and 686 mm width provide plenty of face area for cooling the 2.5L diesel under load. When the rest of the cooling system is in good shape this spec supports towing campers or work trailers. Clean fins and correct coolant mix are still important. Regular checks help keep temps steady on long grades.

Suitable for Nissan Navara D40 with YD25 2.5L diesel engine and manual transmission from 2008 onwards for Thailand-built models. Fitment is specific to vehicles matching this engine and transmission combination.
