Pay special attention to hoses that have been in operation for four or more years. Hose failures increase dramatically after that period .The best advice is to suggest replacement every four years for most vehicles. Vehicles operating under severe conditions may require more frequent replacements. And remember, to prevent the risk of hose failure We recommends that if you are replacing one hose, that you should change all major cooling system hose at the same time.
