The Koyorad radiator for Toyota Hiace KDH 3.0L manual keeps your work van on the road with a core size of 510 mm high and 650 mm wide that handles constant stop‑start runs. An inlet of 38 mm and outlet of 38 mm match factory hoses so you can swap it in and get out there again. The integrated transmission cooler supports manual driveline cooling on 2014-on rigs doing courier runs or site work.

The core sits at 27 mm thick with tightly stacked fins built to shed heat in slow traffic and on hot bitumen. A 10 mm breather port helps move trapped air out of the system so temperatures stay predictable when you tackle long gradients. The tanks and mounts are laid out to line up with standard Hiace brackets so the gear feels like factory kit. It is a smart buy for anyone wanting reliable cooling hardware.

Q: Does this radiator fit automatic Toyota Hiace models?

No, this unit suits manual transmission models only. The hose routing and cooler connections are matched to the manual KDH 3.0L layout. Automatic models often use different cooler arrangements. Always match your transmission type and engine code against this manual‑only specification.

Q: Do I need new hoses when installing this radiator?

Not necessarily, as the inlet and outlet are both 38 mm to suit standard hoses. However, any hose that feels hard, cracked, or swollen should be replaced at the same time. Fresh clamps and coolant are also good practice. This keeps the whole cooling circuit reliable.

Q: Is a transmission cooler included in this radiator?

Yes, an integrated transmission cooler is built into the radiator tank. The cooler uses dedicated ports so the gearbox fluid can transfer heat into the main core. This helps stabilise driveline temperatures on climbs and in traffic. Always reconnect lines carefully and check for leaks on first run.

Q: What coolant capacity does this radiator add to the system?

The exact coolant volume is not specified for this unit. The total system capacity will depend on engine, hoses, and heater core combined. Always fill with manufacturer‑approved coolant mix until the system bleeds clear of air. Recheck levels after the first heat cycle and top up to the mark.
