Yes, I have another stupid question. I notices that when I turn off my E38 there is a fan that keeps running. It ran for about 15 minutes eariler today. Is that normal. I am assuming it is cooling the engine and radiator. I wanted to make sure this was normal for it to run for several minutes after it is shut off.

Thanks to all.

I have noticed that not only does my car do it, but my Acura used to do it as well. I believe that it is a mechanism to make sure the car cools off.

as long as your battery is ok, u should have no problems... hell even my bike did it... i think its just to keep cooling since once you turn off the engine no oil is circulating through, so the fan helps the engine not over heat

just my .02

Very normal. A lot of cars do it to ensure that things cool down nicely and whatnot. It is a little trippy especially if you come back from doing something and the fan is still cooling down the motor.

Thank you for the info. I thought it should do that, but just wanted to make sure. The battery is only 2 months old so I should be fine.
