I can't find if this question has been discussed but is there a recommended idle time to cool down the turbochargers (3.5 eco-boost); especially after heavy towing?
There does not seem to be anything in the ops manual.

I recall this might have been recommended for diesels and was certainly a requirement for turbocharged aircraft engines. It seems to me that allowing them to cool down before shutting down the engine might be a good thing. Don't want to get into the debate about the autostart stop feature though.

Thanks for your insight.

 

I found elsewhere that that cooling down the turbos is not the big deal it used be since they are cooled differently from the oil cooled only versions. I'll probably use premium fuel and just idle mine down for a few minutes when pulling the trailer.

 

 

I read something about how they were plumbed to allow the oil to "thermosiphon" and cool even after the truck was shut off. A couple of minutes is probably fine.

 

It's not a big deal any longer. The turbos on the F-150 EcoBoost engines for the last several years have auxiliary cooling to prevent oil coking.

 

They are oil cooled and water cooled.

 

Agreed. I did a bit of research after my post on this thread. Apparently, even after a long hard pull...you can just shut down the motor.
Modern turbos don't need you to do anything extra.

They are designed for the masses, which that means lots of folks that are bad at maintenance and don't take care of stuff. I don't think there are even any turbo failure threads on this site....which tells us more than anything.

So, for the OP...the recommended idle time after driving or heavy pulls is 0 minutes and 0 seconds.

 

Thank you gentlemen. This tech has certainly come a long way. I really think that in general terms having (1) the level of performance, (2) reliability at a (sort of) (3) reachable price point is amazing. It used to be you could only have 2 out of the 3 points.

 

They are Oil Cooled and Engine Antifreeze Cooled, They do create allot of Heat but are Quenched Quickly.
