Why does the Cruze's fan start spinning as soon as the engine is started?
1 Answers
The reasons why the Cruze's fan starts spinning as soon as the engine is started are as follows: 1. The air conditioning was not turned off: There is no issue with the car's cooling system; it's just that the air conditioning was not turned off when the engine was last shut down. When the engine is started again, the air conditioning will operate, causing the fan to spin to make the condenser work. 2. A problem with the coolant temperature sensor: This causes the engine control unit (ECU) to fail to recognize the coolant temperature signal, leading the engine to enter a fault mode. The so-called fault mode is an emergency mode of the engine itself. When an important sensor or component signal is missing, the ECU operates according to a preset mode to ensure the engine can continue running normally.
