Gates 22510 Premium Molded Coolant Hose Upper Radiator Hose

The Gates 22510 is a precision-molded upper radiator coolant hose engineered as a direct OE replacement for select vehicle applications. Pre-shaped to exact factory specifications, this hose installs cleanly and seals reliably without modification or unnecessary strain on cooling system connections.

Constructed with an EPDM rubber tube and cover, the Gates 22510 resists heat, ozone, and chemical coolant degradation — the leading cause of hose failure. A synthetic fiber knit reinforcement layer prevents collapse under vacuum while maintaining flexibility during installation.
