[DeGiselle]

The solutions for the dashboard showing low water temperature are: 1. The water temperature sensor is damaged; 2. The coolant in the car is insufficient. The reasons for high water temperature in a car are: 1. Scale deposits in the radiator and engine water jacket, leading to poor heat dissipation and rising water temperature; 2. The thermostat is damaged, preventing coolant from entering the radiator circulation; 3. The water pump is damaged or the drive belt is slipping, causing poor water pump performance; 4. Insufficient antifreeze leads to poor engine heat dissipation; 5. The cooling fan is faulty or running at low speed. The solutions for high water temperature in a car: 1. Clean the scale deposits in the engine; 2. Inspect or replace the thermostat; 3. Inspect or replace the water pump; 4. Add antifreeze to the engine; 5. Check the cause of the fan malfunction or low speed.
