This Jayrad JR2078J radiator slots into Toyota HiAce RZH vans with 2.4 litre petrol engines built from 1999 to 2005 and restores factory style cooling performance. The core stands 575 millimetres high and 638 millimetres wide so it keeps coolant temps steady in city traffic and on hot job sites. The 25 millimetre core thickness gives enough surface to shed heat without choking airflow at low speed. The tanks tie into 34 millimetre inlet and outlet necks which match the original HiAce hose sizes so you keep the setup simple. The integrated transmission cooler helps automatic gearboxes cope when you tackle hills fully loaded or sit on the highway for hours. The whole unit suits tradies and tourers who want built tough cooling gear that fits first time and keeps the van ready to get out there again tomorrow.

Q: Does this radiator fit all 1999–2005 Toyota HiAce models?

This radiator suits Toyota HiAce RZH models with 2.4L petrol engines from 1999–2005. It is not intended for diesel or different engine codes. Always match the 575 mm core height and 638 mm width to your existing unit. If your original dimensions differ, this is not the right radiator.

Q: Is there a built-in transmission cooler in this radiator?

Yes, this radiator includes a transmission cooler provision. That suits HiAce models with automatic transmissions that use an in-radiator cooler. You will need to connect the existing transmission cooler lines to the new unit. Check for any leaks after installation and top up transmission fluid to the correct level.

Q: Can I reuse my original radiator hoses with this unit?

The inlet and outlet use 34 mm necks, which match standard HiAce RZH 2.4L petrol hose sizing. Most owners will reuse existing hoses if they are still in good condition. Many mechanics prefer to fit new hoses while the system is apart. Fresh clamps and coolant are also commonly replaced at the same time.

Q: What should I check before ordering this radiator?

You should confirm your HiAce is a 2.4L petrol RZH built between 1999 and 2005. Measure the existing radiator core height and width to match 575 mm by 638 mm. Check that your vehicle uses an in-radiator transmission cooler if it is an automatic. Matching these details reduces downtime and avoids returns.
