The Koyorad JR7170K radiator steps into the nose of Subaru Liberty Outback automatic models from 03/2014 plus Impreza from 2007 Forester from 2008 and Exiga from 2009. The core runs 340 millimetres high and 686 millimetres wide so it deals with slow climbs and long freeway runs without crowding the fans. A 16 millimetre thick core keeps coolant temps in check when you tow or sit in traffic on a 40 degree day. The gear includes a 375 millimetre long transmission cooler built into the tank so the auto fluid dumps heat at the same time as the engine coolant. Both inlet and outlet necks sit at 40 millimetres so your factory hoses line up and clamp straight on. Match these measurements to your old radiator and you are set with a smart buy for regular touring and city work.

Q: Does this radiator fit manual transmission models?

No, this radiator is listed for automatic transmission models only. The integrated 375 mm transmission cooler is designed for auto fluid, which manual cars do not use. Manual models often have different tank fittings and internal passages. Always match your original radiator part and transmission type before ordering this gear.

Q: Do I need to modify my existing radiator hoses to use this unit?

No, the radiator uses 40 mm inlet and outlet necks that match the standard hose diameter on the listed Subaru models. As long as your hoses are in good condition they will clamp straight on. Check for cracks or swelling and replace old hoses while the system is drained. Fresh clamps and coolant help the whole setup last longer.

Q: Is the transmission cooler inside this radiator enough for towing?

The built-in cooler measures around 375 mm and is sized for the factory towing specs of these Subaru models. Many owners run this style cooler for everyday towing within the vehicle limits. Heavy towing in hot regions may still benefit from an extra external cooler. Talk with your mechanic if you regularly haul at maximum tow weight.

Q: What checks should I do before installing this radiator?

First, measure your old core height, width and thickness and confirm they match 340 mm, 686 mm and 16 mm. Next, confirm the inlet and outlet necks are both 40 mm and in the same positions. Inspect fan shrouds and mounts so the new core sits correctly. A pressure test after installation helps confirm the system is sealed and ready for use.
