Gates 23064 Premium Molded Lower Radiator Coolant Hose

The Gates 23064 is a factory-molded lower radiator coolant hose engineered as a direct OE replacement for automatic transmission-equipped vehicles. Precision-molded to match original equipment specifications, this hose installs quickly and accurately without modification, restoring proper coolant flow and engine temperature management.

Gates molded coolant hoses are constructed with an EPDM tube and synthetic fiber knit reinforcement, topped with a heat-, ozone-, and chemical coolant-resistant EPDM cover. The compound is specifically engineered to resist electrochemical degradation (ECD)—the leading cause of premature hose failure—which occurs when coolant, hose material, and metal fittings interact to form micro-cracks that compromise hose integrity.
