You will need to replace them eventually.

Check your owner’s manual for the recommended interval. In today's vehicles, hoses carry vital fluids under high pressure. Replacing them at the recommended interval can prevent a breakdown or serious engine damage. Quality-tested Mopar_® hoses offer precision fit, optimal service life, and original-equipment performance. When it’s time to replace your hoses, or if you see any damage or leaking, see your Chrysler, Dodge, FIAT^®, Jeep_® or Ram dealer. We’re sure to have the hose you need in our parts department.
