The Koyorad radiator for Hilux TGN121 and TGN110 slots straight into the 2.7 litre 2TR-FE bay and keeps temps in check when you load the ute. A core size of 550 by 651 millimetres gives enough face area for slow beach work and long bitumen stretches. The 34 millimetre inlet and outlet suit factory hoses so you can bolt it up and get out there again.

This radiator runs a 16 millimetre thick core so airflow from the stock fan stays on point without stressing the viscous hub. An integrated 375 millimetre transmission cooler handles heat from the automatic box on towing runs or sand driving. The dimensions track the Toyota 164000C280 spec so mounts and shrouds line up without drama. That makes it a smart buy for Hilux owners wanting factory-style cooling performance in Aussie conditions.

Q: Does this radiator suit manual transmission Hilux models?

No, this radiator is suited to automatic transmission models only. The integrated 375 mm transmission cooler is designed for the auto fluid circuit. Manual models do not use this cooler and often have different fitting layouts. Always match the transmission type before ordering replacement cooling gear.

Q: What engine code does this radiator match in the Hilux?

This radiator suits the Toyota 2TR-FE 2.7 litre petrol engine. That engine is used in TGN121 and TGN110 Hilux models from 05/2015 onward with an automatic gearbox. Matching the 2TR-FE code helps confirm hose positions and core sizing. Check your build plate or handbook to confirm the engine code before purchase.

Q: How can I confirm this is the right size for my ute?

Measure your existing radiator core height, width and thickness and compare them to 550 mm, 651 mm and 16 mm respectively. Also confirm the inlet and outlet necks are 34 mm in diameter. Matching these numbers plus the vehicle details gives a strong check. When in doubt, speak with your mechanic for a visual comparison.

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

Yes, it is built to match the factory specification used on towing rated Hilux models. The 375 mm integrated transmission cooler assists with managing auto fluid temperatures when hauling or driving in soft sand. Keeping the core clean and coolant fresh is still critical. Regular maintenance will help the setup handle sustained loads.

Suitable for Toyota Hilux TGN121 and TGN110 models with 2.7L 2TR-FE petrol engine and automatic transmission from 05/2015 onwards. Supplied radiator matches OE reference 164000C280. Professional installation is recommended to ensure correct coolant flow and transmission cooler connection. Always confirm core dimensions and hose diameters against the original radiator before fitment.
