How often should radiator hoses be replaced?

Most hose manufacturers recommend replacing hoses every four years. V-belts should be replaced every three years or 36,000 miles. The incidence of failure rises sharply after the fourth year of service for hoses and third year for belts. The lifespan of a typical serpentine belt is about five years or 50,000 miles.
