Product Description and Specifications

The Gates 21587 radiator coolant hose is made from EPDM, a synthetic rubber known for its resistance to heat, ozone, and coolant chemicals. The hose features a molded shape with a centerline length of 13.7 inches (348 mm), designed to fit specific cooling system layouts. The hose ends have different inside diameters—1.25 inches (32 mm) on one end and 1.5 inches (38 mm) on the other—to accommodate varying connection points within the cooling system. This hose does not include springs or quick connect fittings, which aligns with the original equipment design for the compatible vehicles.
