The Koyorad JR7917HD radiator steps straight into Hino Ranger FD and GH trucks from 2003 on and FG 500 Series Pro rigs that run manual boxes, with a core standing 720 mm high and 634 mm wide to match the factory opening. The 36 mm thick core deals with long climbs and slow traffic where heat builds up. The 55 mm inlet and outlet line up with standard hoses so you can get out there without odd adapters. This gear uses a solid crossflow core at 36 mm thickness to move coolant evenly under load. An 8 mm breather port helps clear trapped air after a service which keeps temperatures steadier in stop start city runs. The built in transmission cooler is set up for manual compatible systems common on work trucks. This is smart buy equipment for anyone who wants proven cooling hardware that handles real Australian haul conditions day after day.

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

Yes, this radiator includes an integrated transmission cooler. The cooler sits inside the main tank assembly and uses the same coolant flow for heat rejection. This helps keep driveline temperatures steadier on long pulls or slow work. Always reconnect the existing cooler lines and check for leaks after installation.

Q: How can I confirm this radiator will fit my Hino truck?

Match both the vehicle details and the dimensions. This unit suits Hino Ranger FD and GH from 2003-on and FG 500 Series Pro with manual transmission. Measure your existing core height and width against the 720 mm by 634 mm specs. Also check the hose diameters are 55 mm for both inlet and outlet.

Q: Do I need to modify my radiator hoses to use this unit?

No, the radiator is built around 55 mm inlet and outlet diameters. These sizes line up with standard hoses used on compatible Hino models. Still inspect each hose for wear or swelling before refitting. Replacing tired hoses at the same time avoids repeat coolant drains later.

Q: What should I check after installing this radiator?

Check coolant level, hose joints, and cooler line seals. Run the engine to full operating temperature and look for any seepage around the 55 mm connections and the transmission cooler fittings. Make sure the 8 mm breather area stays dry. Recheck the coolant level after the first proper drive once any air has purged.
