This Koyorad radiator slots into Toyota Hilux TGN16R models with the 2.7L four‑cylinder and manual gearbox, with a core that measures 500 mm high and 650 mm wide so you can tackle slow climbs and highway stints without the temp needle creeping up. The 16 mm thick core pairs with 34 mm inlet and outlet necks, so your factory hoses line up and the gear keeps coolant moving like it should.

The aluminium core stretches the full 650 mm width to dump heat fast in high ambient temps, while the compact 16 mm thickness keeps airflow clean through the grille. An integrated transmission cooler suits the listed manual and A/P setup, which means fewer extra parts and cleaner line routing. With a matching 500 mm core height and OE‑style 34 mm connections, this kit is a smart buy for Hilux owners who want cooling gear built tough for local conditions.

Q: Does this radiator suit all 2.7L Hilux models from 2005 on?

It suits Toyota Hilux TGN16R 2.7L 4‑cyl models from 2005 onwards with the specified drivetrain setup. Always match the TGN16R chassis code and 2.7L engine to avoid fitment issues. Check your build plate and compare core dimensions of 500 mm x 650 mm x 16 mm before ordering. If your vehicle differs, you may need a different Koyorad part number.

Q: What hose sizes does this radiator accept?

It accepts hoses with 34 mm internal diameter at both inlet and outlet. The radiator uses a 34 mm inlet neck and a 34 mm outlet neck to match the listed Hilux configuration. Reusing factory hoses in good condition usually works with these sizes. If hoses are worn or swollen, plan to replace them with 34 mm ID units.

Q: Is a separate transmission cooler required with this unit?

A separate cooler is not required for the compatible setup because the radiator includes an integrated transmission cooler. The built‑in cooler is configured to suit the specified drivetrain arrangement. You will still need to connect the transmission lines correctly and flush the system as part of installation. Some owners may still add an auxiliary cooler for heavy towing, but that is optional.

Q: Can this radiator be used to upgrade to a thicker core?

This unit maintains a 16 mm core thickness, so it is not a thicker‑core upgrade. The radiator is intended to match OE‑style dimensions of 500 mm height, 650 mm width and 16 mm thickness. If you are chasing a larger‑capacity upgrade, you would need to look for a different core size. Staying with this thickness helps keep fan and shroud clearances correct.

Suitable for Toyota Hilux TGN16R models with 2.7L 4‑cylinder petrol engines from 2005 onwards. Compatible with vehicles running a manual transmission (M/T) with air conditioning and power steering (A/P). Radiator includes an integrated transmission cooler to suit the specified drivetrain setup. Professional installation is recommended to match OE hose diameters of 34 mm inlet and 34 mm outlet and to ensure correct coolant and transmission line connections.
