What is the reason for the Touareg's water temperature staying at 99 degrees with the fan constantly running?
1 Answers
Water temperature staying at 99 degrees with the fan constantly running is because the turbo fan is cooling the turbo, which is a normal phenomenon. More information about the turbo fan is as follows: 1. Delayed fan shutdown: When the engine is running, the temperature distribution in the entire water channel is not uniform, and there are localized high-temperature spots. When the water pump stops running, these heat spots cannot be dissipated, so the fan delays shutdown for the purpose of cooling, which is a normal phenomenon. 2. Sensor: Although the car is turned off, the temperature has not yet dropped. The electric fan is controlled by the sensor. If the car is parked under the sun in summer, the electric fan may still rotate even when the car is not running, as long as the temperature reaches a certain degree. This situation is very normal.
