Ecoboost turbo question!!!

[MavisTheMaverick]

This is my first turbo vehicle and I like to keep my vehicles well maintained so I can keep it for a long time. My question is about turbo cool down. I've heard it's good to let the vehicle idle for like 30 seconds to 1 minute to allow the cooling system to properly cool off the turbo, but I've also heard it's not needed on newer turbos because the system basically does this for you but I've never heard it doing anything after I shut it off ao I'm just curious if this is true or not. Thank you!

Not necessary at all on these engines.

I do disable to engine start/stop each time I drive it. One of the reasons is for the turbo and keep a constant flow of oil to it when hot.

Unless you are really flogging it hard, or doing heavy towing in high heat, you're fine to shut it down like a NA engine. But I believe it's still sound practice to give it a minute or so if you've been pushing it hard for extended periods, even with the cooled bearings & synthetic oils.

Turbo or not, If I’m fresh off the interstate I’ll give my motor and turbo a minute of my time
and a few ounces of fuel to cool down with.
I could care less if it’s needed or not.

If my riding mower, pressure washer and snow blower manuals recommend a cooldown period, and they do, then giving a cool down to my turbo charged truck is a no brainer.

those engines run pretty much full throttle though and they're air cooled

I do not use any in my hybrid Maverick but do put about 2-2.5 oz of Lucas fuel treatment per tank of regular with alcohol into my riding mower and side by side as well as diesel tractor. Live in central Texas near Austin and start them about every six weeks year around (my winterization), while rotating noco g5 maintainer on several batteries. Currently mower-maverick#1-sidebyside-maverjck#2-tractor, pretty much weekly but if dome light doesn't come on that Maverick changes rotation schedule.

It's the lack of lubrication to the turbo after you shut down. It can be still spinning after shut down. I've had turbo timers in past turbo vehicles. Now I just give it 15 seconds of idle before shutting it off.

OP, recommend you do a Google search on "do modern turbocharged engines need a cool down". You'll find some pretty educational stuff out there (also some gibberish).

As always, consider the source and be appropriately judgmental of any information you find online.

Did controls for oil n gas biz, compressor controls. On few of bigger machines with turbo, 2,00-5,000 hp, they used prelube and postlube functions. Prelube to circulate oil to turbo before an engine start. Once engine starts, engine oil pump feeds lube oil. Postlube when engine shutdown, to cool turbo, prevent coking of oil deposit.

Were the turbos on these machines water cooled as the Ecoboost turbo is?

Don’t think so.

Water cooled turbo + full synthetic oil = no oil coking. No need to cling to a practice from 20 years ago.

If Ford is willing to cover the turbo for 10 years under their extended warranty without suggesting a cool down period is needed and they shoulld know, I'd say it's not needed.

But if were towing 4K at 70 mph and pulled into a rest area, I' d probably let it idle for a bit.
