At what temperature does the Volkswagen Tiguan's cooling fan activate?
1 Answers
Generally, the engine radiator cooling fan activates around 90°C. More relevant details are as follows: 1. After the car engine operates for a certain period: The radiator fan automatically turns on when the engine's coolant temperature rises to prevent overheating. Additionally, the fan also activates during hot weather when the air conditioning is in use. The cooling fan shuts off again when the coolant temperature drops to a certain level. Modern vehicle cooling fans are mostly electric. 2. When the coolant temperature reaches approximately 90 degrees: The fan operates at low speed. 3. When the coolant temperature reaches about 105 degrees: The fan starts running at high speed. Of course, different vehicle models may have varying temperature settings for fan operation. Therefore, it's best to use antifreeze coolant in your vehicle, as its boiling point exceeds 100 degrees before it boils.
