Just driven my MY02 for about 20 miles - parked car in garage and fan was furiously churning away .... surely the engine's not overheated that quickly ??? anyone experienced this before ?

 

Don`t worry, nothing is wrong. My my00 is the same especially if you have the AC switched on. I have noticed that when the ignition is switched off then the fan stops,most car`s i have had the fan has continued .
