This Koyorad radiator is a smart buy if your Prado GRJ120R manual from 2003–2009 runs hotter than it should. The core sits at 650 mm high and 595 mm wide, so it lines up with the factory mounts and fan shroud without drama. A 27 mm core thickness keeps decent airflow for slow hill climbs and highway stretches. Both inlet and outlet are 35 mm, so your existing hoses and clamps still line up.

The integrated transmission cooler suits setups that route gearbox fluid through the radiator shell, helping keep driveline temps under control on long hauls. That 650 x 595 mm face area gives plenty of contact for coolant and air when you are towing or loaded up. The compact 27 mm thickness keeps things tidy in the engine bay with standard fans and cowls. It is straightforward, purpose-built cooling gear that lets you get out there without overthinking the radiator side of the setup.

Q: Does this radiator come with new hoses or a cap?

No, this radiator is supplied as a bare radiator assembly only. You reuse your existing radiator hoses if they are in good condition or replace them separately. A new radiator cap and fresh clamps can be purchased as additional gear. This keeps the core unit focused on the main cooling job while giving you choice on supporting parts.

Q: Can this Koyorad radiator be fitted to an automatic Prado?

This specific JR2401J unit is listed for Toyota Prado GRJ120R manual models only. Automatic variants can run different transmission cooler layouts and mounting points. Always match the part number to your vehicle build details. If you own an automatic, check for the correct Koyorad cross-reference rather than using this manual-only unit.

Q: Do I need to modify the fan shroud to fit this radiator?

No trimming should be required when fitting this radiator to a compatible Prado GRJ120R manual. The core height of 650 mm and width of 595 mm are specified to align with the original shroud. Existing shroud mounting clips and bolts can be reused. Always loosely assemble the shroud and radiator first to confirm clearances before final tightening.

Q: Is coolant included with the radiator?

No, coolant is not supplied with this radiator. You will need to purchase the correct type and volume of coolant separately. This allows you to select fluid that matches your engine manufacturer recommendations. Flushing the system and refilling with fresh coolant at install time helps the new core work at its best.

Suits Toyota Prado GRJ120R with manual transmission built between 2003 and 2009. Intended as a direct replacement radiator assembly for this model. Check core size of 650 mm height and 595 mm width against the existing unit before install. Professional installation is recommended to ensure correct hose routing and bleeding of the cooling system.
