The full rundownProduct details
Keep your EJ’s cooling system fresh and flowing with genuine Subaru radiator hoses — a matched pair for the job done right the first time.
This kit replaces both the upper and lower radiator hoses, the two main coolant paths between your engine and radiator.
Old hoses harden, swell, or split over time, especially around clamps and bends. Don’t wait for one to pop — replace them together for full reliability.
