The Koyorad radiator in this size keeps a Subaru 2.5 litre turbo happy when you load the wagon with gear and point it at a long hill. The core sits at 342 millimetres high and 686 millimetres wide so it lines up with factory mounts and shrouds without drama. The 25 millimetre thickness and 375 millimetre transmission cooler give steady temps when you tow or crawl in low range.

This setup runs 39 millimetre inlet and outlet necks so your original hoses bolt straight back on. The 13 millimetre breather port helps shift trapped air out of the system which means more of that coolant actually touches the tubes and fins. The dimensions suit Forester XT models from 08 2008 to 12 2012 and Impreza WRX from 2010 on with autos which makes it a smart buy if you want known sizing.

Q: Does this radiator come with new hoses or clamps?

No, this radiator does not include hoses or clamps. You re-use your existing hoses and clamps if they are in good condition. Many owners choose to fit new hoses at the same time because the system is already drained. Fresh clamps can also help maintain consistent pressure on older plastic necks.

Q: Is the transmission cooler built into this radiator?

Yes, this radiator includes an integrated transmission cooler that measures 375 mm. The auto transmission fluid passes through this internal cooler to shed heat into the coolant and then into airflow. You connect the existing transmission cooler lines to the fittings on the bottom tank. Always check fluid level after refitting.

Q: Will this radiator fit manual transmission models?

This model is specified for automatic transmission variants. Manual cars do not use the same transmission cooler circuit and may have different part numbers and plumbing. Always match your vehicle build date engine size and transmission type against the listed applications. If in doubt our crew can help you confirm the correct gear.

Q: Do I need to modify the fan shroud or mounts?

No modifications are expected when this radiator is matched to the correct Subaru applications. The core height of 342 mm and width of 686 mm are set up to line up with factory brackets. The mounting points and tanks are made to accept the original fan shroud hardware. Always test-fit before filling with coolant to confirm clearances.

Suitable for Subaru Forester XT 2.5L Turbo models built from August 2008 to December 2012 with automatic transmission. Also suits Subaru Impreza WRX 2.5L models from 2010 onwards with automatic transmission. Fitment requires removal of the original radiator and re-use of existing hoses, clamps, fans and shrouds if serviceable. Professional installation is recommended so coolant bleeding and transmission cooler line reconnection are carried out correctly.
