Buick Lucerne overheating issue with repeated thermostat replacements and current water pump replacement needed on Buick Lucerne

Some Buick Lucerne owners report experiencing persistent overheating issues even after multiple thermostat replacements and the need for a water pump replacement. These problems may be attributed to factors such as coolant leaks, which can occur in components like the water pump, radiator, or hoses. Additionally, some owners find that a malfunctioning radiator fan can exacerbate overheating by failing to cool the engine effectively. Despite replacing the thermostat several times, there is a possibility that the new thermostats are also faulty, disrupting the engine's cooling system. Furthermore, an inefficient water pump can lead to inadequate coolant circulation, contributing to overheating. If these issues continue after addressing these components, it is advisable for owners to consult a professional mechanic for a thorough diagnosis and resolution.
