The Koyorad JR7920HD radiator drops straight into Hino Ranger FD and GK trucks from 1999 to 2003 with J08C engines and manual gearboxes, with a core sized at 720 mm high and 634 mm wide so you can tackle long runs without watching the temp gauge. The 36 mm thick core gives enough surface to deal with long pulls and stop start work while the 55 mm inlet and outlet keep factory hose sizing simple. This gear lines up with OE references 160904674 and 6070, so you get a smart buy that matches the original layout without mucking around with brackets. The trans cooler setup is built into the tank, keeping plumbing tight and neat on the chassis. The dimensions are set for Hino Ranger mounts, so the shroud and fan stay where they should, ready to get out there on regional highways or local delivery loops.

Q: Does this radiator fit both FD and GK Hino Ranger models?

Yes, this radiator suits Hino Ranger FD and GK models from 1999 to 2003 with the J08C engine and manual transmission. Always confirm the build year on the compliance plate before ordering. Match the J08C engine code on the vehicle paperwork. It also helps to compare the listed dimensions against your existing radiator for extra peace of mind.

Q: What are the core dimensions of this Koyorad radiator?

The core measures 720 mm high, 634 mm wide, and 36 mm thick. Measuring the old radiator between the tanks gives you the core height and width. The 36 mm figure refers to the thickness of the finned core section. Matching these numbers keeps the fan shroud and mounting hardware lined up correctly.

Q: What hose sizes does this radiator use?

Both the inlet and outlet necks are 55 mm in diameter. Checking the internal diameter of your upper and lower radiator hoses should give the same 55 mm size. If your hoses are badly worn, using the same diameter makes replacement straightforward. Keeping the correct hose size helps maintain proper coolant flow and clamp sealing.

Q: Does this radiator include a built-in transmission cooler?

Yes, this unit includes transmission cooler provision within the tank assembly. The cooler ports sit on the tank as per the factory layout, so the existing lines can be reconnected. Keeping the cooler in the radiator helps manage oil temperature during heavy work. Always flush or replace transmission fluid as required when swapping cooling components.
