What is the primary function of this upper coolant hose?

This hose carries hot coolant from the engine's thermostat housing to the top of the radiator. It's a critical part of your diesel engine's cooling system, helping to prevent overheating.

Does this hose come with clamps?

This part is for the molded coolant hose only. Clamps are typically sold separately, so be sure to check if your existing clamps are in good condition or if you need new ones for installation.

How do I know if I need to replace my upper coolant hose?

Look for visible signs of wear such as cracks, swelling, or hardening of the rubber. Leaks around the hose connections or a persistent sweet smell of coolant can also indicate a problem.

Product Details

This is the Gates upper molded coolant hose specifically for your 2009-2010 Chevrolet Silverado 2500 HD or 3500 HD, or its GMC Sierra counterparts, equipped with the V-8 6.6L Diesel engine. It's designed to replace the original hose that carries coolant from the engine to the radiator, playing a key role in keeping your engine from overheating.

Gates makes these hoses using a strong, heat-resistant rubber compound that can handle the high temperatures and pressures found in a diesel cooling system.

This helps ensure a leak-free connection and proper coolant flow, which is crucial for the longevity of your diesel engine.
