Gates 00-07 Peterbilt 379 Caterpillar C15 Diesel Upper Eng. To Pipe Straight Coolant Hose (2-Ply)

This 2-ply coolant hose from Gates is built to connect the upper engine to the pipe on your 2000-2007 Peterbilt 379 equipped with a Caterpillar C15 diesel engine. It's a straight hose, designed to handle the specific routing and temperature demands of that heavy-duty cooling system. The 2-ply construction means it's well-built to resist the constant pressure and heat cycles found in diesel applications, helping to prevent leaks and maintain consistent coolant flow.

Gates uses EPDM rubber for these hoses, which is a material known for its good resistance to heat and coolant degradation. This helps ensure the hose lasts a long time under the hood, even with the high operating temperatures of a C15 engine. It's a straightforward replacement part, intended to fit right into the existing system without needing modifications, keeping your truck's cooling system running smoothly.
