About the Gates Molded Coolant Hose Product Line

The Molded Coolant Hose line by Gates focuses on delivering pre-formed, modular hoses that simplify installation and improve coolant flow efficiency. This product line incorporates molded shapes and quick connect fittings to reduce installation time and ensure leak-free connections. The 23962 part benefits from this design approach, offering a ready-to-install solution tailored for specific heavy-duty truck applications.

Detailed Product Description

The Gates 23962 radiator coolant hose is constructed from EPDM rubber combined with plastic and steel reinforcements, providing resistance to heat, pressure, and coolant chemicals. Its molded shape includes two branches and three quick female connectors, allowing for secure and efficient coolant routing within the engine bay. The hose’s centerline length of 53.87 inches (1368 mm) and consistent 2.37-inch (60 mm) inside diameters at both ends ensure compatibility with the cooling systems of Chevrolet Sierra and Silverado 2500 and 3500 HD models. The absence of internal springs reduces potential failure points, while the modular design supports straightforward replacement and maintenance.
