Detailed Product Description

The Gates Molded Coolant Hose 23278 is engineered to meet the specific cooling system requirements of Pontiac Sky and Saturn Solstice vehicles. Its molded construction eliminates the need for additional clamps or fittings, providing a secure and leak-resistant connection. The EPDM material offers excellent resistance to heat, ozone, and coolant chemicals, ensuring durability under demanding engine conditions. With a centerline length of 30.2 inches (767 mm) and matching inside diameters of 1.3 inches (33 mm) on both ends, this hose maintains consistent coolant flow and system pressure.

This hose does not contain any internal springs or quick connect fittings, simplifying installation and reducing potential failure points. The molded design also helps maintain the hose’s shape and prevents kinking, which can disrupt coolant circulation.
