Detailed Product Description

This radiator coolant hose is made from EPDM, a synthetic rubber known for its resistance to heat, ozone, and automotive fluids. The molded construction ensures a precise fit with end diameters of 0.62 inches (16 mm) and 0.75 inches (19 mm), accommodating specific radiator and engine connections. With a centerline length of 5.8 inches (147 mm), the hose is designed to fit tightly without kinking or collapsing. The absence of an internal spring allows for unobstructed coolant flow, which is critical for maintaining engine temperature and preventing overheating.
