The Koyorad JR2402J radiator steps straight into a Toyota Prado KDJ120 from 2006 to 2009 or a KZJ120 turbo diesel manual from 2003 to 2007, keeping coolant moving through a 650 mm high core. With a 600 mm core width and 36 mm thickness, there is enough surface area to tackle long highway pulls or slow low-range climbs. Inlet and outlet diameters of 38 mm line up with factory hoses, so the gear slots into a standard 120 Series setup without drama.

The integrated transmission cooler section supports auto KDJ120 models across heavy towing or sand work, while the 8 mm breather connection hooks to the stock overflow hose. This radiator is a smart buy if the original unit is clogged, corroded, or weeping along the tanks. With dimensions matched to OEM spec, you get known fitment and consistent temperature control across Australian heat, corrugations, and stop-start city traffic.

Q: Does this radiator fit all 120 Series Prado models?

No, it suits specific diesel variants. It is listed for Toyota Prado KDJ120 models from 2006 to 2009 and KZJ120 turbo diesel manual models from 2003 to 2007. Petrol 120 Series models use different radiators with other dimensions and hose layouts. Always compare your existing radiator measurements and hose positions before ordering.

Q: Is the transmission cooler built into this radiator?

Yes, it includes an integrated transmission cooler. The spec table lists a transmission cooler, which means the automatic transmission fluid lines can connect directly to the radiator tank. This helps manage gearbox oil temperature during towing or slow work. Always flush and reconnect lines carefully to avoid contamination.

Q: What hose sizes does this radiator suit?

It suits 38 mm inlet and outlet hoses. Both the inlet and outlet diameters are specified at 38 mm, which matches the standard hose size on the compatible Prado diesel engines. This lets you reuse good existing hoses or fit new ones without adaptors. Check your current hose size with a vernier or tape before fitting.

Q: How can I confirm this radiator will physically fit my vehicle?

Match core size and mounting style to your original. Measure your existing radiator core height, width and thickness and compare them to 650 mm, 600 mm and 36 mm. Check that the inlet, outlet and breather ports are in similar positions and that your shroud and mounts line up. If everything matches closely, you have a high chance of correct fitment.

Suits Toyota Prado KDJ120 models built from 2006 to 2009. Suits Toyota Prado KZJ120 turbo diesel manual models built from 2003 to 2007. Fitment is for turbo diesel variants only. Installation should be carried out by a competent mechanic following Toyota cooling system procedures. New coolant and fresh hose clamps are recommended at the time of installation. Check core size and outlet positions against the original radiator before final fitment.
