Mazda 6 temperature rises to 80% on hills with cooling fan constantly running on flat roads on Mazda 6

Some Mazda 6 owners report experiencing engine temperature issues, such as rising to 80% on hills while the cooling fan runs constantly on flat roads. This rising temperature may indicate coolant problems, including low levels or air trapped in the cooling system, which can hinder proper coolant circulation. Additionally, the persistent operation of the cooling fan might be attributed to a malfunctioning thermostat, a broken water pump, or even a blown head gasket. Other potential causes of engine overheating reported include a blocked radiator, cracked cooling system components, or a faulty water pump. Owners have noted that a rising temperature gauge could signal various issues with the vehicle's coolant system, fan, radiator, or thermostat. It is recommended that affected owners consult a qualified mechanic to diagnose and address these overheating concerns effectively.
