The reasons for the car's cooling fan running constantly when the water temperature is not high are: 1. Failure of the cooling fan assembly or its wiring; 2. Detachment of the engine water pump impeller or damage to the water pump; 3. Malfunction of the water temperature sensor. The solutions for this issue are: 1. Inspect the fan wiring; 2. Replace the water pump and water temperature sensor. The reasons for an increase in car water temperature include: 1. Leakage in the cooling system or insufficient coolant; 2. Malfunction of the water temperature gauge; 3. Excessive scale in the cooling system, leading to poor heat dissipation; 4. Loose or broken water pump or fan belt; 5. Engine operating under prolonged overload conditions.
