Product Details

Dayco’s Curved Radiator Hose line focuses on formed coolant hoses that match the routing and connection points used in vehicle cooling systems. This hose uses EPDM construction for coolant service and a curved profile that supports the lower radiator hose path on the Honda CR-V. The 1 3/16-inch inside diameter at both ends and 1 19/32-inch outside diameter at both ends help maintain a consistent fit at the connection points. Part number 73051 is the correct reference when searching for a lower radiator coolant hose for 2015-2016 Honda CR-V applications.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
