Gates 21413 Molded Coolant Hose

The Gates 21413 molded coolant hose is built for upper radiator hose applications that require an OEM-style formed shape and precise end sizing. Made from EPDM, it supports reliable coolant routing on select Chrysler, Dodge, and Plymouth vehicles from the mid-1980s through 1990.
