Turbo coolant pump after shutdown

[VADER42]

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..............

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
