Answer: Radiator hoses can last for several years; sometimes they can last for over ten years. However, it is important to check the condition of your radiator hoses periodically. Wait until your engine cools completely, and then feel your radiator hoses. They shouldn’t feel too hard and brittle or too soft and mushy. Inspect the hoses for any cracks as well. You should also check the clamps that hold the radiator hoses in place. If there appears to be any excessive wear or any cracks in your radiator hoses, have them replaced immediately.
