Detailed Product Description
The Gates 51410 radiator coolant hose is made from a combination of EPDM rubber, plastic, and steel, materials chosen for their resistance to heat, pressure, and coolant chemicals. The hose features a molded construction with one branch and two quick connect fittings—one male and one Henn style—allowing for secure and leak-free connections. The inside diameters at both ends measure 1.4 inches (36 mm), with an additional branch diameter of 0.7 inches. Multiple centerline lengths (18 mm, 28.5 mm, and 724 mm) accommodate the specific routing paths required in Mercedes-Benz C and E-Class models. This modular hose design supports efficient coolant flow and system reliability without the need for springs.
