This Koyorad radiator runs a core size of 340 mm high and 686 mm wide so it fits Subaru Liberty, XV, Outback, Forester and Impreza bays without drama. The 16 mm thickness keeps the fins open so it still sheds heat when you are crawling in low range or sitting in summer traffic. The 40 mm inlet and 40 mm outlet line up with factory hoses so you can keep the rest of the cooling gear as is.

The tank layout covers both manual and auto transmissions and the built-in transmission cooler saves you adding extra hardware under the bonnet. The unit suits systems without a breather port so it matches specific factory tanks used in these models. The broad 340 x 686 mm face gives enough area to handle long climbs and towing loads. If your old radiator core is clogged or leaking this is a smart buy to get out there again.

Q: Does this radiator fit both manual and automatic Subaru models?

Yes, it suits compatible manual and automatic models. The radiator includes an internal transmission cooler so autos can hook transmission lines straight to the tank. Manual cars simply do not use those ports. Always cross-check your original core size and hose layout with the listed 340 x 686 x 16 mm dimensions before ordering.

Q: What measurements should I check before ordering this radiator?

Match core height, width and hose diameters. Measure your existing core between the tanks and compare to 340 mm high and 686 mm wide on this unit. Confirm the thickness around 16 mm so shrouds and fans sit correctly. Check the inlet and outlet hose diameters are 40 mm so your existing rubber hoses clamp up without adapters.

Q: Does this unit replace radiators with a breather port on the tank?

No, this model is for systems without a breather port. Some Subaru radiators run a small extra breather outlet on the plastic tank while this one does not. If your original unit has that extra fitting it is worth choosing a version that matches it. A like-for-like tank layout helps bleeding and keeps the cooling system working as designed.

Q: Is an external transmission cooler still required with this radiator?

This radiator includes an internal transmission cooler tank. Many factory automatic Subarus use this style and run fine in everyday driving. Some drivers still add an external cooler for heavy towing or sand work. In that case the built-in cooler can stay in series to help keep transmission temperatures stable.

Suitable for select Subaru Liberty, XV, Outback, Forester and Impreza models with manual (M/T) and automatic (A/T) transmissions that use a radiator without breather. Fitment requires matching the core size of 340 mm x 686 mm x 16 mm and 40 mm inlet and outlet diameters with the original unit. Professional installation is recommended to ensure correct hose routing and transmission cooler line connections.
