Below you will find coolant hoses for the car which look really nice and give the engine compartment extra color. Radiator hoses are often made in a dull black color and with blue silicone hoses, you have the opportunity to get an engine compartment that looks nice and unique. Radiator hoses connect the engine's radiator ducts/outlets to the car's radiator which is often located in the front of the car for best cooling. The cooling takes place by air coming through the ribs on the radiator by the car moving or the radiator fan running. Coolant water is moved through the hoses. Our coolant hoses allow you to use the coolant you want. They are really good and flexible.
