Chevrolet Aveo persistent overheating issue despite thermostat and heating sensor replacement on Chevrolet Aveo

Some Chevrolet Aveo owners report experiencing persistent overheating issues even after replacing the thermostat and heating sensor. These problems may stem from insufficient coolant levels or leaks in the system that lead to coolant loss. Additionally, owners have noted that radiator blockages can hinder heat dissipation, contributing to overheating. Some have found that a malfunctioning radiator fan fails to provide adequate engine cooling, while others have identified issues with the water pump not circulating coolant effectively. A clogged radiator can further obstruct the cooling process, and some owners have discovered that a leaking head gasket can also be a contributing factor. Understanding the overall cooling system, including components like the coolant pump and temperature sensor, is crucial for diagnosing these issues. In some instances, multiple problems, such as simultaneous coolant leaks and overheating, may need to be addressed individually for effective resolution.
