Gates 05-06 Peterbilt 335 Caterpillar C7 Diesel Upper - Pipe To Rad. Molded Coolant Hose

This is the upper radiator hose for a 2005-2006 Peterbilt 335 equipped with a Caterpillar C7 diesel engine. It connects the engine's pipe to the radiator, carrying coolant to keep your engine from overheating. Gates is a well-known name in cooling systems, and this hose is built to handle the demands of a heavy-duty truck.

This molded hose is shaped specifically to fit the routing of the C7 engine in your Peterbilt, ensuring it doesn't kink or rub against other components. It's made from EPDM rubber, which is a strong material that resists heat and coolant degradation, helping it last longer in tough operating conditions. Proper coolant flow is critical for engine longevity, especially in a diesel that works hard.
