What is the solution for the Chevrolet Cruze's electric fan running continuously?
2 Answers
Chevrolet Cruze's electric fan running continuously can be resolved by: 1. Adding antifreeze; 2. Replacing the rubber hose; 3. Replacing the thermostat. Reasons for the electric fan running continuously: 1. Engine overheating due to insufficient coolant; 2. Engine overheating caused by radiator leakage, with loose or damaged rubber hoses leading to water leakage; 3. Thermostat failure, where water cannot be sent to the radiator or the amount sent is too little even when the temperature reaches the baseline. The Cruze is a compact car launched by Chevrolet, with body dimensions of 4666mm in length, 1807mm in width, and 1460mm in height, and a wheelbase of 2700mm.
I also drive a Cruze, and the constant running of the electric fan is really annoying. Last time I encountered this issue, the fan kept buzzing even after parking, which not only drained the battery but also raised concerns about it dying. The problem usually lies in the cooling system's sensor—either the small component is faulty or clogged with dirt, causing the fan to misjudge the engine temperature as high and stay on. Also, check if the relay or control module is malfunctioning, as the Cruze's circuit design is prone to short circuits and aging. For a quick fix, I first inspect the fuse box and try replacing a fuse. If that doesn’t help, a professional shop with a diagnostic tool is needed to read the trouble codes. The key is not to delay—prolonged fan operation can strain engine performance and even cause premature wear. Regularly cleaning the engine bay to prevent debris buildup around sensors can help avoid recurrence. If the AC is on, the fan may also engage more frequently, so checking the AC system is also a good idea.
