This Koyorad radiator drops into Toyota Prado GRJ120, RA/T and GSJ15 from 2003 to 2009 and FJ Cruiser GSJ15 from 2011 to 2016, so you can keep the 6-cylinder working hard without watching the temp gauge all day. With a 649 mm core height, 593 mm width and 27 mm thickness, it lines up with factory shrouds and fans, making it a smart buy when the original core starts seeping or clogging.

The inlet and outlet both sit at 34 mm diameter, so your existing hoses stay in play and you keep spares simple in the touring kit. An internal 250 mm transmission cooler looks after the auto when you tow campers or haul gear across soft sand or long hills. The whole setup is built tough for Aussie heat, helping your Prado or FJ get out there from the bush to the beach without drama.

Q: Does this radiator include an internal transmission cooler for automatic models?

Yes, this radiator includes an internal transmission cooler measuring 250 mm. That cooler section lets automatic transmission fluid pass through the tank to shed heat into the main core. It suits vehicles that originally came with a combined radiator and transmission cooler. Many owners still add an external cooler for heavy towing, but this unit on its own matches the factory layout.

Q: How can I confirm this radiator will fit my Prado or FJ Cruiser?

Match your vehicle model code and build year to the listed applications. This radiator suits Toyota Prado GRJ120, RA/T and GSJ15 built 2003–2009, and Toyota FJ Cruiser GSJ15 built 11/2011–2016. You can also measure your existing core to check for 649 mm height and 593 mm width. If in doubt, have your mechanic compare mounting points before ordering.

Q: Do I need new hoses to install this Koyorad radiator?

Not necessarily, as the inlet and outlet necks are both 34 mm to match factory sizing. If your current hoses are in good condition and suit a 34 mm neck they can usually be reused. Many workshops still recommend fresh hoses when changing a radiator to avoid future leaks. Inspect for cracks, softness or swelling before making the call.

Q: Is this radiator suitable for vehicles used for towing or long-distance touring?

Yes, its core size and integrated 250 mm transmission cooler are suited to vehicles that see regular highway and touring use. The 649 mm high by 593 mm wide core provides ample surface area for airflow in hot conditions. Keeping coolant and transmission temperatures under control helps protect the engine and auto on loaded trips. For heavy towing, pair it with correct fluids and a well-maintained cooling system.
