This Koyorad radiator drops into Toyota Prado KZJ120 auto diesel models from 2003 to 2006 so you can tackle long highway runs and dirt tracks without heat drama. The core stands at 650 mm high and 600 mm wide so it sheds heat well when the fan and airflow are working hard in low range or traffic. A 36 mm thick core keeps enough coolant volume moving for touring loads. Inlet and outlet necks measure 38 mm so they line up with standard hose sizes and keep flow predictable on remote trips. An integrated 250 mm transmission cooler section supports the auto when you tow or crawl. Part codes E97CAA and TLH-34001 give a clear match for ordering or workshop jobs. This is straightforward cooling gear built tough for Aussie conditions and a smart buy for an ageing Prado.

Q: Does this radiator include an integrated transmission cooler for the automatic Prado?

Yes, this radiator includes an integrated transmission cooler section measuring approximately 250 mm. That section allows the automatic transmission fluid to shed heat through the same core used by the engine coolant. It helps stabilise gearbox temperatures during towing or sand driving. It also keeps the plumbing neat compared to a separate external cooler.

Q: Which Toyota Prado models will this Koyorad radiator suit?

This radiator suits Toyota Prado KZJ120 automatic diesel models built between 2003 and 2006. The compatibility aligns with vehicles running the referenced part numbers E97CAA and TLH-34001. Always confirm your VIN and engine code against workshop data before ordering. If your Prado is petrol or manual you will need a different radiator.

Q: What hose size does this radiator accept at the inlet and outlet?

Both the inlet and outlet necks on this radiator are sized at 38 mm diameter. That matches the specified hose size for the compatible Prado KZJ120 automatic diesel models. Using the correct hose diameter helps maintain designed coolant flow. It also simplifies installation because standard replacement hoses can be used.

Q: How large is the main cooling core on this radiator?

The main cooling core is 650 mm high and 600 mm wide with a thickness of 36 mm. This size provides a substantial frontal area for airflow across the fins. It also preserves enough internal volume for coolant circulation under towing or loaded conditions. The dimensions align with factory-style fitment for the listed Prado models.
