Fan on after shut down, how long?
Just wondering how long do your fans run after shut down?
Should I sit in the car and let it idle a bit before shutting it off? |
It takes as long as it takes. Let the car decide.

+1. unless its staying on for hours at a time, let it do what it is meant to do
|
10 minutes.
|
it will shut off when the motor is cool enough just let it go i let mine go and just go in the apt...if you go out like 2 hours late and it's still on then i would go to a dealer but if it's like a couple minutes you're cool
|
haha, i remember, i was like WTF???? when this first happen, i love my 8
|
Well down here in the desert it can run for a long time. I park in the garage and it seems like an eternity before it shuts off. 10+ minutes on a regular basis.
|
^^ same here, its always FKN hot in texas....

Thats why I did like others did in the forum and went to an oversized aftermarket radiator, went as far as drilling relief holes in the tsat to get the needed water flow thats obviously killing engines time and time again from overheating. wirekit the fans to energize together helps, the hot climate here on the gulf coast sometimes gets brutal unforgiving, thats why I have a backup plan to releive the heat....CO2 cannistered shorts that deploy to cool my ass. heh it works........

Well, if you don't like the fan staying on when you shut off your car, go back, turn the ignition to ON (don't start the car) and back off, it'll stop the fan from running.

I have yet to have the fan stay on it has been so cold this year... Some cars do this a lot and other's don't. Our Honda did it like a maniac and our Subaru never does it.
|
lol, there should be a sticky about this. Every person new to the 8 freaks out when that fan comes on. Its louder than when the car is running lol.
|
I freaked out more when Jiffy Lube did my oil and the differential was dripping all over my driveway. They didn't clean up the mess they left behind, I ended up going to the dealer about it too...
|
It's not as unusual as you may think. Occasionally the fan on my Miata—and on my '02 VW GTI—would stay on for a long time, too.
|
Doesn't every car made in the last 20 years do this already?

Let the fans run they'll turn off. I wouldn't worry until the day they actually do drain your battery and you have to push start it. then I'd get a new battery. |

Not recommended. The fans come on for a reason. Just let them do their job.

with the mazsport fan mod, it turns on more often while driving so when i shut off it doesnt need to stay on for too long. usually less than 30 seconds even after hard driving.

the reason they stay on is because there is no water flow past the sensor when the engine is off - not an issue to turn the fans off that way if it annoys you .....

Sitting there idling is just defeating the purpose. As everyone else has said, jut let it do its job - it knows when to shut off.
And yes, most radiator fans have been working this way since the fan belt went the way of the Dodo. btw: my wife's iMac fan was running at high speed for a long time last night (cool indoor ambient despite our heat wave at the moment), but a simple SMC (ROM) reset did the trick. Horse of a different feather, but related. |
Yesterday was the first time I heard mine run. Then again, it did set a new record here yesterday (101, ugh!). Kinda funny because I had just read this thread on Friday. Yeah, it's loud, almost as loud as the engine! Doesn't bother me; just funny to hear.
