This Koyorad radiator suits Subaru Liberty and Outback 3.0L auto models with a core that stands at 350 mm high and 690 mm wide. This kit steps straight into factory locations so you can get out there again without chasing custom brackets. This setup runs a 16 mm thick core so clearance around fans and pulleys stays workable when you tackle tight engine bays. This radiator uses aluminium core construction with composite tanks sized around that 16 mm core thickness to manage heat on long pulls. This gear includes an internal transmission cooler matched to the automatic layout on these Subarus so the cooling circuit stays tidy. This setup keeps the 28 mm twin inlet and 40 mm outlet sizing that Subaru used from the factory so your existing hoses usually line up. This radiator is a smart buy for touring rigs that cop real Australian temperatures.

Q: Does this radiator include a built-in transmission cooler for the automatic gearbox?

Yes, it includes an integrated transmission cooler. The cooler is built into the radiator tank, so the transmission fluid lines connect directly without a separate external cooler. This keeps the plumbing neat and within the original Subaru layout. It also means you are replacing both engine and transmission cooling in one job.

Q: How can I confirm this radiator will fit my Subaru Liberty or Outback?

Match your vehicle engine and build years and check measurements. This radiator suits 3.0L automatic Liberty models from 09/2003–09/2009 and Outback 3.0L autos from 2003–2009. You can also compare your old core size of roughly 350 mm high by 690 mm wide and check the 28 mm inlet and 40 mm outlet hose sizes.

Q: Do I need to replace hoses and coolant when fitting this radiator?

It is recommended to fit fresh coolant and inspect hoses. Old hoses can harden or crack when moved during removal, especially on vehicles over ten years old. Fresh coolant mixed to the correct ratio helps protect the new aluminium core from corrosion. Many workshops treat radiator replacement as a good time to renew clamps as well.

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

It is suitable as a factory-spec replacement for touring setups. The 350 mm by 690 mm core offers similar cooling capacity to the original, which many owners use for towing camper trailers and small vans. Keeping fins clean and coolant in good condition will help it cope with extended hill climbs. For heavy towing loads some owners may still add auxiliary transmission cooling for extra margin.

Suitable for Subaru Liberty 3.0L automatic models built from 09/2003 to 09/2009 and Subaru Outback 3.0L automatic models from 2003 to 2009. Radiator core dimensions are 350 mm high by 690 mm wide by 16 mm thick with 28 mm twin inlet connections and a 40 mm outlet. Unit includes an integrated transmission cooler for automatic gearboxes. Check your existing radiator dimensions and hose diameters before ordering. Professional installation is recommended.
