This Koyorad radiator steps straight into Toyota Kluger AXUH78R Hybrid 2.5L and GSU70R 3.5L V6 autos with a core size of 700 mm high by 587 mm wide. You get a 16 mm thick core that keeps coolant moving through plenty of fin area on long highway pulls or slow climbs with the family and gear loaded. The 38 mm inlet and outlet line up with factory hoses so the setup stays simple. The alloy core and plastic tanks keep weight down without giving up cooling area across the 700 mm by 587 mm face. An integrated transmission cooler suits the auto box so you can tackle towing and city traffic without extra hardware. The mounting points suit later Kluger bodies from 2021 on so the kit bolts up clean. This is smart buy gear for anyone keen to get out there without worrying about overheating dramas.

Q: Does this radiator fit both Hybrid and V6 Kluger models?

Yes, it suits AXUH78R 2.5L Hybrid from 2021 on and GSU70R 3.5L V6 from 2022 on with automatic transmissions. That means one part number covers both drivetrains in the current body shape. It helps when you are ordering for mixed fleets or planning future upgrades. Always confirm your build code and engine size against the vehicle compliance plate.

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

Yes, this radiator includes an integrated transmission cooler circuit for automatic models. The cooler sits inside the tank so you do not need a separate core for standard duty work. It keeps line routing tidy and close to factory. For heavy towing many drivers still add an external cooler in series for extra temperature control.

Q: What hose size does this radiator use?

Both inlet and outlet necks use a 38 mm outside diameter. That matches the factory Kluger upper and lower radiator hoses. You can usually reuse existing clamps if they are in good condition. Many owners still choose to fit new hoses and clamps while the cooling system is open for peace of mind.

Q: Can I use this radiator for towing and long-distance touring?

Yes, the 700 mm by 587 mm core is sized to manage heat under towing and highway use within the vehicle’s rated limits. The integrated transmission cooler helps manage automatic transmission temperatures during long pulls. For caravan or camper work an extra auxiliary cooler can further stabilise temps. Keeping coolant and ATF serviced on schedule is just as important as the hardware.
