This Koyorad radiator suits Toyota Hilux GGN 4.0L V6 autos from 2005 up so you can keep the ute ready to tackle heat and hills. The core sits at 525 mm high and 655 mm wide so it lines up with the factory support and fan shroud. The 27 mm thickness manages coolant volume without choking airflow when you load the tray or tow on hot days. The inlet and outlet both run a 34 mm diameter so your existing hoses and clamps match straight up. The built in transmission cooler uses a 34 mm spec to service the auto box under tow weights common in Aussie touring. The mounting pattern follows the original layout so the gear suits standard front panels. This setup is a smart buy when your old radiator shows blocked fins or leaking end tanks.

Q: Does this radiator suit manual transmission Hilux models?

This radiator is specified for automatic transmission Hilux models. The listing references A/T and an integrated transmission cooler with a 34 mm spec. Manual models often use a different configuration without cooler lines. Check your VIN and existing radiator setup with your mechanic before ordering. Matching the core size and hose layout helps avoid fitment issues.

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

The inlet and outlet are specified at 34 mm to match factory hoses. If your existing hoses are still in good condition they can generally be reused on this unit. Many owners choose to replace old hoses while the system is drained. A fresh set of hoses and clamps can reduce the chance of leaks later. Always inspect for cracks or softness before refitting.

Q: Is this radiator suitable for towing and heavy loads?

The core size and integrated transmission cooler support towing use. The 525 mm by 655 mm core area provides good heat rejection for the 4.0L V6 under load. The built in transmission cooler helps manage gearbox temperatures when towing within the vehicle limits. Keeping the cooling system clean and using the correct coolant mix also matters. Regular checks before long trips are still important.

Q: Will this radiator fit all 2005-on Toyota Hilux models?

Fitment is targeted to GGN 4.0L V6 automatic variants. Other engines and transmissions can use different radiator layouts and mounting points. Always confirm engine code GGN and transmission type against your registration details. Comparing the listed core dimensions with your existing unit is a good final check. If unsure talk with your workshop or our team before purchase.
