This Koyorad radiator slots into Toyota Hiace TRH petrol vans with a 2.7 litre engine and manual box running between 2005 and 2015. You get a core size of 510 by 652 by 36 millimetres so the van can tackle slow metro traffic or highway runs without the temp gauge creeping up. The 38 millimetre inlet and outlet line up with factory hoses so you can get out there again sooner after a changeover. The unit includes twin breather ports in 14 millimetre and 8 millimetre sizes to help clear air pockets when you refill the system. An integrated transmission cooler keeps drivetrain temperatures in check on long hauls or heavy load days. The TRH dash 05 pattern matches standard 4020 style mounting points across the front support so the gear sits right and works as intended in Aussie heat, dust and stop start delivery work.

Q: Does this radiator suit all Toyota Hiace models with a 2.7L petrol engine?

No, it suits specific TRH series Hiace vans with a 2.7L petrol engine and manual transmission from 2005 to 2015. Always match the TRH code and year range to your compliance plate before ordering. Check your existing radiator dimensions against the 510 x 652 x 36 mm core size. If you are unsure, our crew can help confirm compatibility.

Q: Is the transmission cooler built into this radiator usable straight away?

Yes, the radiator includes an integrated transmission cooler circuit that is ready to connect. The existing cooler lines from your Hiace can be transferred across, provided the threads and seats match. Inspect the old lines for damage or corrosion before refitting. New sealing washers or clips may be needed during installation.

Q: Do I need to replace the radiator cap and hoses at the same time?

It is not mandatory, but it is strongly recommended when fitting a new radiator. Old hoses can be soft or cracked, which risks leaks once the new core is installed. A fresh cap helps maintain the correct system pressure. Replacing these components together reduces the chance of repeat cooling issues.

Q: Can this radiator handle long-distance driving in hot Australian conditions?

Yes, the 510 mm high and 652 mm wide core provides substantial surface area for heat dissipation. The 36 mm thickness gives good coolant volume for highway cruising and loaded work. Correct coolant mix and a clean fan shroud are still essential. Routine checks of coolant level and external fin condition will help the setup go the distance.
