The rubber hoses that connect the radiator to the engine and the engine to the heater core are one of the most common leak points. These often deteriorate over time through normal use. If your cooling hoses are swollen, cracked, especially on the ends, or have bulges in them it is probably time to replace them.
If you have a radiator hose leak, fixing it is usually pretty simple. ADRAD agents carry hoses specific to most vehicles, meaning they are constructed with the right length, shape and diameter to fit perfectly on your car.
