At what temperature does the Volkswagen Tiguan's cooling fan activate?
2 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.
After driving a Volkswagen Tiguan for several years, I've noticed that the fan usually kicks in when the coolant temperature is between 95°C and 100°C. I've experienced situations in summer traffic jams where the temperature soared, and the fan buzzed to help cool things down. If the fan doesn't turn on when the temperature is too high, it might be due to sensor or wiring issues, which could lead to engine overheating damage. I make it a habit to glance at the temperature gauge weekly—normal range should hover around 90°C. Maintaining the cooling system in good condition is crucial, such as timely coolant replacement to avoid contamination and cleaning the radiator fins to reduce dust buildup. Neglecting these small details might lead to bigger troubles, so it's important to develop a routine of checking your car's condition.
