Fans Running After Turned Off

[Maddog2873]

Curious question. I took a few friends out for a spin and we did probably a dozen or so launches from a stop. When I got back home with the car, I turned it off and noticed the fan was still running. It stayed like that for about 5 minutes after getting back home. I could feel cold air around the front of the grill and hot air coming out from under the sides of the car.

This would be normal to me if the car was on, but I have never experienced this on a car after it has been turned off. Is this normal for the Stinger?

If you did what you said, this would be normal as everything would have been really hot & the sensors would keep thermo fans on until it cooled to an acceptable temperature, also give your coolant level a quick visual check to ensure it’s not low.

 

[Maddog2873]

Gothca, will check it out. It was also around 10pm and 52 degrees out so I imagined the cooling from the crisp night air would have helped it cool down a bit faster.

Yes, it's normal for most modern vehicles with thermostatically controlled electric fans. If as you say you can feel hot air exiting underneath, it's doing its job.

I have heard the fans run multiple times on this car and other newer vehicles, just never while the car is completely off.

It's not unusual in a lot of vehicles these days for the fan to remain on for a short period after engine is off.
I've driven the car on numerous very hot days over summer but haven't had the fan stay on sofar.

Normal, you can always pop the hood for a bit if its doing that to aid in the cooling process.

I think beating on it then parking it is really bad for components like the turbos, which rely on oil circulation to keep bearings cool.

I've been wrong before..

Trust no cars were beaten in the making of this thread. Car got to casually drive for about 5 minutes after the last 0-60 run before it got parked and turned off. And it was a very cool night.

Hmmmm, I've run my car hard for testing, but it always cooled down enough before shutdown to not warrant the fans running after shutoff. Did you recently top off or drain/fill coolant? All I can imagine is you have a hot pocket (lol) of air that tripped the sensors into thinking the car was overheating and the car ran the fans even after shutoff for this reason...

I haven't made any changes to the coolant. The car isn't even 2 months old yet so I haven't had a need. I am going to check the levels when I get home to see if they are low.

Normal.

My last twin turbo 6 vehicle (15 exploder) did the same thing.

When parking the Stinger in the garage in the summer (ambient temps mid-20s C) the fan often stays running for a bit after shutting the car off - and that's without doing any spirited driving. My other car does the same thing.

Clearly not enough cooling down running time. A dozen launches! That seems a bit excessive. But the car kept letting you do them. So it must have been borderline demand. I've read that LC won't even engage if the trans fluid is too hot.

The manual states: (page 5 | 19)

A warning screen message will pop up on the screen if the transmission fluid temperature is above a certain level while using Launch Control. Also, Launch Control will be automatically deactivated.[*]

To address the issue as above, a driver should cool down the transmission fluid temperature by driving the vehicle. (Driving at a constant speed over 60 KPH is highly recommended)

[*The message on the screen will say: "Launch control not available due to high transmission temperature"]

 

[Maddog2873]

A dozen launches! That seems a bit excessive.

Apologies, I didn't mean using launch control, I just meant launching from lights or stop signs by flooring it. And they weren't back-to-back. For example, launch onto a highway, cruise at highway speeds for a few minutes before exiting and taking another on ramp. Most of the driving was on the highway and after each launch (flooring it, not LC ) there would be a few minutes of cruising at highway speeds before having more fun.

I see. "Civilized" launches. The kind I do. That makes the behavior of your fans very weird. Your trans fluid should not be overheated simply from rapid acceleration.

I know this thread is old but I just experienced the same thing on a 55 degree day. I did a few take offs on some back roads when having to make turns but otherwise was just cruising at normal speeds, nothing too crazy. I've def driven it harder for longer before and with it hotter outside and it never kept the fans on. I popped the hood and the fans were blowing cold air but there was def some hot air coming out from both sides of the car from underneath. I figured it was normal and it did shut off by itself after a while.

My Stinger GT2 engine overheated and I had to drive to a parking lot and let the engine cool (fan running). Engine temperature gauge was almost the red zone.....? Coolant level was low so I added some coolant. Next day ......temperature gauge was indicating that my engine was getting park so i parked in the garage. I schedule a service appointment at the Kia dealership (engine has 19,500 miles of normal driving). At this point, I seriously thinking about trading my Kia Stinger GT2 for a Lexus SUV.....I am very disappointed....

You've had a trouble-free experience so far, is that right? All cars have issues at some point. I bet that your overheating issue is something simple. It's under warranty, regardless. And you're taking care of your car by being cautious, just like the owner's manual advises.

I had this happen on my S4, the thermostat was failing and failed about 2 weeks after I noticed the fans running after shut off. Might be the same problem?
