Detailed Product Description

The Gates Molded Coolant Hose 23185 is engineered to meet the specific cooling system requirements of the Pontiac GTO. Its EPDM construction offers excellent resistance to heat, ozone, and coolant chemicals, which helps maintain hose integrity over time. The molded design ensures a precise fit with end diameters of 1.38 inches (35 mm) and 1.54 inches (39 mm), matching the radiator and engine connections for optimal sealing and minimal leakage risk.
