What causes the Buick Excelle's fan to keep running continuously?
1 Answers
Buick Excelle's fan keeps running continuously for the following reasons: 1. Reason one: Whether the electronic temperature control coolant temperature meets the requirements. Most car radiator fans nowadays operate with electronic temperature control, so the fan will only start running normally when the coolant temperature in your car reaches the required level. If the temperature is too low, the radiator fan won't turn on. 2. Reason two: Faulty relay. If the coolant temperature meets the requirements but the car radiator fan still doesn't work, it could be an issue with the fan's relay. 3. Reason three: Insufficient antifreeze. This can cause the engine coolant temperature to rise. Check the coolant circulation to see if it's obstructed. Additionally, you can inspect components such as the coolant temperature sensor, water pump, thermostat, and cooling fan, as any of these could lead to increased coolant temperature.
