The Koyorad JR2400J radiator drops into Toyota Prado KZJ120 manual 3.0L diesel models from 2002 to 2007 and keeps the coolant under control when you load the wagon. A core that measures 650 mm high and 595 mm wide gives plenty of face area when you crawl in low range or haul at highway speeds. Inlet and outlet necks at 38 mm line up with factory hoses so the setup stays tidy on long runs. The 36 mm core thickness balances coolant volume and airflow so the fan and shroud can still do their job in slow traffic or sand work. An integrated transmission cooler sits inside the tank to keep driveline temperatures in check without extra fittings hanging off the front. Dimensions match the Prado support panel and shroud so mounts line up and the gear works with existing hardware for a smart buy cooling upgrade.

Q: Do I need new hoses with this radiator?

You can use hoses that correctly match the 38 mm inlet and outlet diameters. Many owners choose to replace older hoses at the same time to avoid future leaks. Check your existing hoses for cracks, softness, or swelling. If they show wear, changing them with the radiator is a smart move.

Q: Is the transmission cooler internal or external to the radiator?

The transmission cooler is integrated within the radiator assembly. This keeps the cooler protected behind the core and simplifies line routing. It also means the cooler benefits from the same airflow as the main core. Always ensure transmission lines are correctly tightened and checked for leaks after installation.

Q: Can this radiator handle towing and touring use in hot conditions?

The large 650 mm by 595 mm core is well suited to sustained load in Australian heat. The 36 mm thickness provides good coolant volume without choking airflow. Properly maintained fans, shrouds, and coolant will also play a big part. Keep the fins clean and the system bled to get the best performance.
