Turbo coolant pump after shutdown

[VADER45]

Most of you have probably noticed that the coolant pump for the turbos will run for a while after turning the car off. I live in the Deep South and it’s brutally hot right now. The pump would run in my car for several minutes after I got home. Over the weekend I tried an experiment.

Opening the hood after shutdown reduced the runtime of the pump to about a minute vs the five or so it would run before. Will I do this all the time? Probably not. Is it nerdy? Yeah. Just found it interesting.

Thanks for the info as I was wondering about this my self . Yep I live in the south and yep its been really hot here also. Later RJD

Yeah noticed it as well, I'm hoping we can get a better heat extraction hood option in the future. Was looking at turbo blankets / aux rad, I am in a cold state 7 months out of the year so no real urgency for me tbh.

You know, I can’t really tell if the Sixpack extractor is functional or not. On my Challenger Scat Pack I could see the heat escaping from the hood vents.

there seems to be a thermal blanket attached to the hood, the sixpack vent does have vents, but I think it would benefit from more heat extraction.

Granted I'm not an engineer, for all I know this was a good idea for the power this thing puts out but unfortunately I am always modding, can't break the habit. If it was possible to get a 5% increase to heat extraction I'd jump on it (eventually).

Maybe a luvered hood.like one on 2017 vett it disapase heat well

You're right, I won't care since it's under warranty..............

 

[aceinspp70]

There should have been an additional way to dissipate the heat. I heard the sound and thought it was the engine fan running after shutting off. Like some cars do. Later RJD

Interesting. Did you drive it a similar distance with a similar driving style? Similar ambient temps? I feel like stomping on the throttle could get them a lot warmer and have the pumps run longer.

Still, a ~4 min difference is pretty significant assuming the car was properly warm both times. I want to get the Mopar hood, or a similar hood with a scoop next summer and this is helping to convince me lol

It was about a 22-mile drive. It's hot as hell outside all last week. Try it yourself, I bet you'll notice how quick they shut off once the hood gets opened.

I believe you, I was just curious about the details

Well drove my 25 mile round trip and temp was 83 and it never came on after my stop at dealer. Later RJD

Interesting. Mine is on after every drive.

What is the temp when driving. Later RJD

What is the temp when driving. Later RJD

Outside? 80's in the morning and high 90's, low 100's in the afternoon. The engine temp stays below half the bar. I haven't bothered to look at the gauge.

 

[aceinspp70]

Only time I heard mine is when the temp got to mid 90s. I did not bother to look at gauge. I think you can go into set up on the steering wheel and actually bring up engine temp. Later RJD

You know, I did just that today after work. I remote started it and walked maybe 60 yards to the car. Weird thing is it read 170 degrees right when I got in. Never seen a car get that hot that fast. But, this is my first turbo car.

 

[aceinspp70]

Yes they warm up fast and you can tell also by the sound of the exhaust. Later RJD

Mine was running coolant in the dead of winter after driving so ambient probably doesn't matter much. I'm betting it has more to do with how warm the turbos get. If you're babying the throttle it probably won't warm them enough to need to run the coolant.

Yeah it gets toasty fast. Tiny engine, big turbos seems to get hot quick. Even my mother's 4 cylinder jeep with the turbo warmed surprisingly fast and that wasn't a performance engine.
