Gates 73-79 Chevrolet C & K Series Pickup 6-Cyl. 250 Lower Molded Coolant Hose

This is the lower radiator hose from Gates, part number 20841. It's specifically molded to fit the 6-cylinder, 250 cubic inch engine found in a wide range of Chevrolet and GMC vehicles from the mid-70s to early 80s. If you're working on a classic C/K series truck, a Blazer, or even some passenger cars from that era, this hose is designed to route coolant correctly from the radiator to the engine block.

Gates makes these hoses with durable rubber compounds that can handle the heat and pressure cycles of your cooling system. Because it's a molded hose, it has the specific bends and curves needed to clear other engine components and avoid kinking, which is crucial for maintaining proper coolant flow. A kinked or collapsed hose can quickly lead to overheating, so using the right shape is important for reliable operation.

This hose is a direct replacement for the original equipment part, meaning it should fit right without any modifications. It's a solid option for anyone restoring or repairing their cooling system on these popular GM vehicles.
