The full rundownProduct details
The genuine Subaru upper radiator hose — built to handle heat, boost, and the long haul.
This hose connects your Forester’s engine outlet to the top of the radiator, carrying hot coolant away from the block to keep temps in check.
Old hoses don’t last forever. Over time they harden, split, or leak near the clamps. Replacing yours is cheap insurance against overheating and blown gaskets.
