Most hoses require replacement – regardless of where they are at on a vehicle – once every four years. However, we recommend following the OE specifications on replacement intervals.
It’s often difficult to look at a hose and know whether it’s faulty. Some physical signs a hose is bad is when it’s collapsed, broken, if it’s brittle or stiff. Most hoses are pliable and soft so anything other than that should indicate the need for further inspection. Other signs that suggest a hose is bad is if you see signs of leaks or bulging around the connection to the clamp.
