Do I need new radiator hoses? Radiator hoses last much longer than they did in the past for many reasons! Consistent vehicle operating temperatures and improved antifreeze compounds as well as improved hose materials have made huge improvements. The best way to make your radiator hoses last is to service the fluid in the cooling system. By servicing the cooling system you will keep the fluid from becoming acidic and deteriorating the hoses. The cooling system should be serviced every four years and the hoses will then last for eight years!
