Default Cooling fan stays on after car off?

I've never witnessed this on any other car so I had to ask. I was driving before with the AC on and it is very hot here now, in the 90s. When I turned the car off, there was a fan noise from the engine still running for several minutes, then it turned off. I assume it's a cooling fan of some kind. Is this normal? It was fairly loud, as if the car was still running (which it wasn't).

Yes this is quite normal with the advent of electrical fans. There is a sticker in the engine compartment that says fan may turn on at any moment and to keep hands clear

I've seen that label, on other cars too, but this is the first car where I ever actually saw this happen...especially so loudly.

The purpose of this fan is to dry out the ventilation system to prevent musty smell.

My last 3 cars did this, and I was always told it was to continue the engine's cooling. Despite the engine being off and no pumps running, the natural convection of hot and cold would still circulate coolant through the system allowing the engine to cool better.

Question Re: Cooling fan stays on after car off?

I know the Auras have the feature MJD112379 is referring too, as do some other Saturn models including the last generation S-series, but my question is when does this fan turn on? Does outside air temperature have to do with the fan turning on? The length of time the a/c is on? The reason why I ask is that it has been close to 100 degrees where I live recently and I have been using my a/c quite a bit . I have not noticed the fan kicking on after my drives. I am not worried about whether or not this feature is working, just curious.

Mine does this but it doesn't stay on. I get out the car in enough time to just hear it spin down.

You mean the blower fan inside the cabin is running?

No it isn't, they aren't even connected in any way. The fan is cooling the engine/radiator, it's not the interior fan we're talking about, it's the engine compartment fan and it's a normal feature. It'll happen if it's really hot out.

Default Re: Cooling fan stays on after car off?

In my 2004 L300.3,the engine cooling fan stayed on for a short time on particularly hot days to help cool the engine compartment.

In addition the car had a "Ventilation Fan Delay Module".This turned the HVAC fan on for 7 minutes at full blast approx 40 minutes after the engine was shut down if the AC had been on for 5 mins or more.

This module was not referred to in the Owner's Manual. I only found out about it when talking to dealer about musty odor. They said module was already there but had to be activated at customer request.!!!After module was activated,the musty odors virtually disappeared. However,it would have been nice if Saturn had told people about this feature in the Manual.
