This Koyorad radiator runs a 650 mm high by 634 mm wide core to keep Hino Ranger Pro FD8JGD1J trucks steady on long pulls. The 36 mm core thickness gives enough coolant volume for loaded runs without blowing out front clearance. A 55 mm inlet and 55 mm outlet line up with standard hoses on 03–09 manual rigs so you can swap it in and get out there again.

The fin block works across that 650 mm by 634 mm face to dump heat in slow traffic and hot headwinds. An 8 mm breather port ties into the overflow so the system can cope with big temperature swings. The tank layout includes an internal transmission cooler matched to the manual spec for this model. It is smart buy gear for Aussie operators who need cooling hardware that matches factory measurements and keeps trucks working.

Q: Does this radiator suit all Hino Ranger Pro models?

No, it suits FD8JGD1J manual models built 03/2003–09/2009. This fitment range matches the core size and hose diameters listed in the specs. If your compliance plate or VIN code differs, the hose positions or mounting points may change. Always cross check your model code and build date before ordering this gear.

Q: Is the transmission cooler built into this radiator?

Yes, this radiator includes an integrated transmission cooler section. The cooler sits inside the tank and shares the same 650 mm by 634 mm core area for heat rejection. This means fewer separate coolers hanging off the front of the truck. Your installer will reuse or adapt the existing cooler lines to the new tank ports.

Q: Can I install this radiator myself at home?

It is possible but professional installation is recommended. The unit uses 55 mm inlet and outlet necks that must align correctly with factory hoses. Poor bleeding or clamp alignment can cause leaks or overheating under load. A workshop can pressure test the system and confirm fan shroud and guard clearance.

Q: How do I check if the breather size is correct for my setup?

This radiator uses an 8 mm breather port on the tank. Measure the inside diameter of your existing overflow hose to confirm it matches the 8 mm spec. A correct match keeps coolant expansion flowing cleanly to the bottle. If the hose is worn or undersized, replace it during the radiator changeover.
