The key function of every car's cooling system is to take out excess heat from the engine, to allow the engine to work at the most efficient operating temperature and to allow the engine to reach its ideal operation temperature in the shortest time possible. Every component of the cooling system is vital in removing heat and in keeping the engine running efficiently no matter what the operating conditions are. Among the vital yet simple parts of the cooling system is the radiator hose. In essence, radiator hoses are rubber lines that carry the antifreeze to and from the radiator to keep the engine cool. It links the engine and the water pump to the radiator. Built from flexible rubbers, these hoses vary in sizes depending on the type of engine you have. The stock radiator hose equipped in your vehicle is outfitted with precision engineering and technology to ensure that it offers long service life. These hoses though also have their share of wear and tear. In most cases you will not know when the hose would fail and need replacement. This is something you should let your trusted mechanic do for you. If the hose is damaged or cracked, it would cause your car to overheat because of lack of coolant. If you think that the temperature gauge is running higher than normal, you better have your car inspected before any damage can take place. Though replacing a worn out radiator hose is easy and fast, in most cases the hoses are tucked away making the job much harder. If this is your car's case, better leave the replacement job to your mechanic. Remember not to put off replacement of your radiator hose as it can result to overheating and even cause the engine to require replacement. This may add up to your repair cost which could be quite difficult for your pocket. A good rule of thumb to follow is to replace your radiator hose every 3 months or 3,000 miles to avoid any further repair cost.
