This Koyorad Navara D23 NP300 diesel manual radiator steps straight into duty with a core height of 720 mm and width of 488 mm, so you can tackle long corrugated roads without staring at the temp gauge. The 27 mm core thickness works well with the factory fan setup, moving enough air at low speed for slow climbs. The 35 mm inlet and outlet necks suit standard hoses, keeping the kit simple when you are swapping it out in the shed. The aluminium core and plastic tanks keep weight down at the nose, which helps when the Navara already carries a bar and winch. Tube spacing across that 488 mm width is set up for steady airflow in hot Aussie headwinds. The built-in transmission cooler lines up with the stock hard lines on manual-equipment variants that still use this housing. Overall dimensions mirror the 720 mm tall factory unit, so the gear works with standard shrouds and mounting points.

Q: Does this radiator suit all Nissan Navara D23 NP300 engines?

This radiator suits diesel D23 NP300 models from 2015-on with a manual transmission. Always match the core size of 720 mm high by 488 mm wide and 27 mm thick to your existing unit. Check that your old radiator also uses 35 mm inlet and outlet hose diameters. If those measurements line up, this Koyorad unit is the right style.

Q: Is the transmission cooler included in this radiator?

Yes, this radiator includes an integrated transmission cooler. The cooler is built into one of the end tanks as part of the assembly. This allows coolant and transmission fluid to exchange heat within the same housing. You will still need to reconnect your existing cooler lines during installation.

Q: Can I install this Koyorad radiator at home?

Yes, many owners install radiators at home if they have the right tools and experience. You will need to drain and refill coolant and possibly transmission fluid. Always follow the vehicle workshop manual for torque settings and bleeding processes. If unsure, a professional mechanic can handle the swap for you.

Q: Do I need new hoses with this radiator?

Not always, as the inlet and outlet necks are both 35 mm like the factory unit. However, old hoses can harden or crack after years of heat cycles. Many owners choose to replace upper and lower hoses plus clamps at the same time. Fresh hoses reduce the risk of future leaks and overheating.

Suitable for Nissan Navara D23 NP300 diesel models built from 2015-on with manual transmission. OEM reference 214104JA1A. Always compare core size of 720 mm height x 488 mm width x 27 mm thickness plus 35 mm inlet and outlet diameters to the original radiator before installation. Professional installation and a full cooling system flush are recommended.
