This Koyorad radiator slots straight into Toyota Hiace KDH 3.0L diesel manuals from 2010 on so you can tackle daily work runs without watching the temp gauge. The core size of 510 by 652 millimetres keeps coolant temps in check on long climbs and stop start delivery work. The 36 millimetre thickness gives solid cooling capacity for loaded vans and constant idling around town. This gear runs 38 millimetre inlet and outlet necks so your factory hoses sit right without drama. The 8 millimetre breather fitting hooks up to the overflow line and keeps expansion where it should be. The unit includes provision for a transmission cooler so drivetrain temps stay stable on heavy days. Koyorad backs their radiators as a smart buy for Aussie conditions from city traffic to country highways.

Q: Does this radiator fit all Toyota Hiace KDH 3.0L diesels?

It fits Toyota Hiace KDH 3.0L diesel manual models from 10/2010 onward. Earlier shapes and automatic variants use different radiator patterns. Always confirm your build date and transmission type before ordering. Matching the core dimensions and hose diameters to your existing unit is a good final check.

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

No, the radiator uses 38 mm inlet and outlet necks to suit standard Hiace KDH hose sizes. Old hoses can harden or crack, so many mechanics still recommend new hoses with a new radiator. Fresh clamps and coolant help the system seal properly. That way your cooling setup is sorted for the long term.

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

Yes, this Koyorad radiator includes provision for a transmission cooler circuit. The cooler helps stabilise transmission fluid temperatures on long highway drives and under load. Always reconnect the cooler lines with fresh seals during installation. After fitting, check for leaks and recheck fluid levels once the van has reached operating temperature.

Q: Can this radiator handle regular highway towing loads?

The 36 mm thick core and 510 x 652 mm face area give solid heat rejection for typical towing within the Hiace rating. Good cooling also depends on clean fins, correct coolant mix, and a healthy fan setup. If the van works hard in hot regions, keeping the grille clear and servicing the cooling system on schedule is important. Regular checks help the radiator keep temps under control.
