This Koyorad radiator steps straight into a Toyota Kluger A/T with the 3.5L V6 and keeps coolant moving through a 475 x 767 x 27 mm core, so you can get out there without watching the temp needle. The built-in transmission cooler runs to 375 mm length, which helps when you tackle long climbs or tow at highway speeds. Factory-style 34 mm hose connections keep the setup simple on GSU45R and GSU40R models.

The core thickness of 27 mm is a smart buy for Aussie heat, giving solid capacity without choking airflow to the condenser and fans. The frontal area of about 0.36 m² lines up with standard Kluger grille openings, so the gear works with stock front bars. Matching 34 mm inlet and outlet diameters keep coolant flow close to factory spec and help the kit go the distance on touring trips.

Q: Does this radiator include an integrated transmission cooler?

Yes, this radiator includes an integrated transmission cooler section measuring approximately 375 mm in length. This cooler is built into the tank and is intended for automatic transmission models. You will need to reconnect the existing transmission cooler lines to the new unit. Always check for leaks after refilling and running the engine to operating temperature.

Q: Will this fit all Toyota Kluger 3.5L V6 models from 2007 on?

It suits GSU45R, GSU40R and 45R Kluger automatic models with the 3.5L V6 where the factory core size is 475 x 767 x 27 mm. You should confirm your vehicle’s build code and original radiator dimensions before ordering. Checking the inlet and outlet neck diameters are 34 mm also helps confirm compatibility. When unsure, compare measurements against the existing radiator on the vehicle.

Q: Do I need new hoses or clamps when installing this radiator?

The inlet and outlet necks are 34 mm, which matches the listed factory hose diameter, so existing hoses may physically fit if they are in good condition. Many installers still recommend new hoses and clamps when changing a radiator. Fresh rubber reduces the chance of future leaks at the connections. A quick visual check for cracks, swelling or hardness helps decide if replacement is worthwhile.

Q: Is this radiator suitable for towing and long-distance touring use?

The core size of 475 x 767 x 27 mm and the 375 mm transmission cooler make it suitable for vehicles that see towing and highway touring. Adequate coolant and transmission oil temperature control are important under sustained load. You should always ensure the rest of the cooling system, such as fans and thermostats, is also in good condition. Using the correct coolant mix and keeping fins clean will help the setup cope with Aussie conditions.

Suits Toyota Kluger automatic transmission models with chassis codes GSU45R GSU40R and 45R running the 3.5L V6 engine from 2007-onward. Fitment is intended as a replacement radiator for vehicles originally equipped with an automatic transmission cooler in the radiator tank. Confirm core size of 475 x 767 x 27 mm and inlet and outlet diameters of 34 mm match the existing unit before installation. Professional installation is recommended to ensure correct coolant bleeding and transmission cooler line reconnection.
