Neglect is the most frequent cause of radiator failure in classic vehicles. Many vintage car owners overlook cooling system maintenance—such as flushing the engine block and changing coolant—which should be done every two years.
In my experience, components like fan belts, hoses, clamps, and water pumps must also be inspected and replaced when necessary. Never use “STOP leak” additives, as they expand and fully clog the radiator, heater core, or engine.
Proper maintenance prevents major issues like clogged radiators, leaks, or blown head gaskets. These avoidable problems often result from deferred repairs and cost thousands to fix. Care and preventative action are always better than being stranded on the road.
