Radiator hoses are an inexpensive but critical part of your car’s cooling system. While they don’t cost a lot of money, they can run up some big bills if they aren’t cared for properly. Every time you drive your car, those hoses have to carry hot coolant at a high pressure; over time, all that heat and pressure will lead them to break down or wear out. While radiator hose repair is pretty straightforward, unless you know what you’re looking for and how to fix the problem, you might not catch it before it becomes a serious issue.
