Why does the cooling fans on your 1999 Jaguar continue to ru n after motor is shut off?

The cooling fans on your 1999 Jaguar may continue to run after the engine is turned off to help dissipate heat from the engine and prevent overheating. This is a normal function designed to protect the engine components, especially if the engine was running hot or if the ambient temperature is high. The fans are controlled by a temperature sensor that activates them when needed, even after the ignition has been turned off. If the fans run excessively or for an unusually long time, it may indicate a malfunction in the cooling system or the temperature sensor.
