How long to idle before shutting it down?

[cblackb]

Hey all, I'm reading that the EGT should be around 300 degrees before you shut off any turbo-diesel engine. Right now I don't have a Pyrometer, soon, but not yet. Any good rules of thumb as to how long to wait at idle before shutting the motor down? Dealer didn't tell me anything like this.

After a hard pull about 3-5 mins...................short runs bout 2 mins. would be good.

under normal driving conditions you dont even need to wait. im sure ill get guys arguing with me about this, and its not a bad idea to let it run, but during most conditions it is absolutely not nessicary, and even more so, it can actually cause problems on a 6.0......

after running it very hard, i would reccomend a couple minutes.......Marc

Back some time ago, coking of the turbo bearings was a real issue. Oil would settle on the hot bearing surfaces and form a coked coating that shortened the bearings' (and turbo's) life. Bearing redesign has eliminated much of the problem. Also, using a good quality synthetic oil will pretty much guarantee that coking will not occur.

Straight from the article..........

Today’s turbo-diesels are a different story. There is really no reason to “cool down” a turbo-diesel these days, but you won’t hurt anything by doing it either. You can still find people who swear you have to do it, but the myth is fading. Maybe they just like to sit and listen to the radio.

The only thing it hurts is the pennies you're idling away each time you let it idle before shutdown, they add up!

Cool thanks for the info, I won't worry too much about it then unless I've been towing or hauling.
