Your Vehicle’s Hoses

hosesRubber hoses would last 10 years if all they did were sit on a shelf. In a car, they are regularly exposed to temperatures around the 212-degree boiling point. At high temps, the plasticizers that make rubber squishy leach out at a faster rate. Once a hose gets hard, it cracks and hot water spurts out. Look first at where both the input and output radiator hoses attach to the engine and to the radiator. The extra stress on the hose from the pipe collar and hose clamp means they typically crack and fail there first. Also check your heater hoses, which run from the engine (usually near the thermostat housing) into the firewall and back. Look for bulges or blisters, which indicate a weakness in the hose wall. If your hoses have cracks or blisters, replace them. As a precaution, buy a hose-patch kit at the local auto parts store.
