What Are the Causes of Low Coolant Temperature?
1 Answers
Coolant temperature low causes are: thermostat failure, shutters stuck in the fully open position, fan clutch sintering, electric fan running continuously, excessively low ambient temperature, or faulty coolant temperature gauge/sensor. The full name of coolant should be antifreeze coolant, meaning it has antifreeze functionality. Antifreeze prevents the coolant from freezing during cold seasons when the vehicle is parked, which could crack the radiator or damage the engine block. It's important to correct a misconception - antifreeze isn't just for winter use; it should be used year-round. In normal vehicle maintenance procedures, engine antifreeze should be replaced annually.
