turning off engine after running all day?

after running all day , do you let the enging idle for a little bit before you shut it off?

 

Usually by the time you pull into the parking lot and get into a spot or maybe finish up a little paper work is long enough. You just don't want to shut off an engine immediately after a good long hard pull. A few minutes is all you need for the turbo to cool down.

 

The other thing is allowing the turbo to spin down at dead idle. High idle doesn't allow that. Give it a good 5 seconds at dead idle. You do not want that turbo spinning with no oil pressure.

 

the fuel saved is minor versus the peace of mind i get by giving it 5 minutes to cool down .

 

I usually pull in my yard and finish up my timecard for the day. That activity alone is anywhere between 1.5-5 minutes, depending on how confusing of a day it was.

 

Yes, and Acerts take at least 5 MIN not seconds to cool/slow down this time of year. In the heat and humidity I've seen mine take up to 15-20 min to cool below 300*.

 

Just to be clear I was talking about dead idle for a few seconds after letting everything cool down.

 

I hope you aint talking 300 on the water, lol

 

Flip your fan ON, it will help cool the Air Charge cooler on the front and help in cooling off the turbos. Also remember, you have the A/C condenser on there creating heat and that air is pulled back into the Air Charge cooler. As soon as I stop, I turn my fan on, it helps keep the truck cool and makes the A/C work better.

 

When you are pulling into the yard do not use you Jake's, coast, do your paperwork, and your walk around, then shut it off you do not need to let it Idle for 5 minutes or longer, most modern engine will shut off in 5 minutes or less, Coking of the turbo does not happen any more the oil is a lot better that the 1960's. and the turbo has a lot more oil the center section does not get as hot as it use to, if it did the paint would burn off.
Just a thought!
