It's always a good idea to do periodic checks of the coolingsystem hoses, especially if they are a few years old. Inspect upperand lower radiator hoses along with the smaller heater hoses. Lookfor cracks, swelling, or any signs of deterioration. Cracks maybecome more noticeable if the hose is squeezed. If replacingradiator hoses, it is wise to replace the upper & lower hosesat the same time even if only one looks bad. Under normal operatingconditions, hoses will break down at approximately the samerate.
