Gates 15-18 Chevrolet Silverado V-8 6.0L Reservoir To Rad. Molded Coolant Hose

This is a Gates molded coolant hose, part number 23808, designed to connect the coolant reservoir to the radiator on a range of trucks and vans. It's specifically made for vehicles like the Chevrolet Silverado 2500 HD, GMC Sierra 2500 HD, and Chevrolet Express 2500, among others from the 2011 to 2016 model years. A molded hose like this is important because it has the specific bends and shape needed to route coolant cleanly and without kinking, ensuring proper flow.

Gates uses a strong, reinforced rubber compound for these hoses, built to handle the heat and pressure found in your cooling system. This means it can resist cracking and premature failure, which is common with older or damaged hoses. Having the correct shape is key; a universal hose might not fit without stretching or forcing, which can lead to leaks or a short lifespan. This hose is shaped to fit right, making installation straightforward for a mechanic or a DIYer.

When you're replacing a coolant hose, it's always a good idea to inspect the rest of your cooling system. Check your radiator, water pump, and other hoses for any signs of wear or leaks. Replacing this hose is a practical step to keep your engine running at the right temperature.
